2. Mechanical Installation

2.1 Heat Loading 2.1.1 General Considerations

The Powerterm CP system uses state of the art switch mode power supply design to provide a compact efficient and long life system. Care should nevertheless be taken when mounting the components of the system to ensure adequate cooling. If a sealed enclosure is to be used ensure that the thermal dissipation of the enclosure is sufficient to keep the internal temperature below the maximum rating when ambient temperature is highest. If the enclosure is to be located outdoors, direct sunlight could add to the heat load in the enclosure, and so it is always preferable to mount the enclosure out of direct sunlight if possible.

2.1.2 Internal Power Dissipation Calculation To calculate the worst case heat dissipated in the enclosure for a system similar to Figure 1-1 you can use the following quick formula:

32)18()( +×= NwattsW

Where N is the number of Powerterm L120P/R T/R’s in the enclosure.

2.2 Panel Layout 2.2.1 Spacing of T/R’s

The PTL120P/R’s produce the most heat within the enclosure. PLT120P/R T/R’s placed side by side MUST be separated by at least 20mm and must have 50mm above and below to allow air convection to flow through the units. The number of Powerterm L120P/R T/R’s that can be mounted in a row are as follows:

Mounting width No. of T/R’s 280mm 3 380mm 4 480mm 5 580mm 6

2.2.2 Placement inside the enclosure The Powerterm L120P/R T/R’s should be placed above the other equipment in the enclosure so that the rising hot air produced by these units does not heat other electronics.

2.3 Mechanical Dimensions This section provides drawings of the physical dimensions of each component covered by this manual.

2.4 Installing the PowerView Operator Interface Terminals 2.4.1 General

The PowerView CP Operator Interface Terminals are designed for use in rugged environments, with an operating temperature range of 0 to 45 deg C. The front bezels are IP65 rated, providing a waterproof front panel when correctly installed. It not recommended that the PowerView CP OIT’s be exposed to the weather or direct sunlight. These products have been tested to conform to European CE requirements for electrical immunity and interference. Care should be taken with correct wire routing and grounding to ensure proper operation.

2.4.2 Mounting the PowerView CP OIT’s Care should be taken when locating equipment behind the unit in the panel to ensure that AC power, wiring, TR Units, contactors, and/or relays and any other source of electrical interference are located away from the rear of the unit.

2.4.3 Panel Mounting 2.4.3.1. Panel thickness

A panel thickness of 1.6mm minimum in steel is recommended for the panel to prevent bowing of the panel when installed.

2.4.3.2. Panel depth The unit can be mounted into panels with an internal depth as little as 60mm. It is recommended that the unit be mounted on the front panel of a steel enclosure, through an appropriate cut out. Allow a clearance of 25mm between the sides of the unit and other panel mounted hardware. Allow clearance for cable connections to the back of the unit. The required depth may vary according to the type of cable used.

2.4.3.3. Installation To install the unit, insert through the panel cut out from the front. Slide the clamps into the 4 holes provided around the case. Tighten the clamping screws in an even pattern until the unit is secured in the panel. Caution : Do not over tighten mounting clamps.

2.4.3.4. IP65 Sealing To seal to IP65 specifications, all supplied mounting clamps must be used and panel should not flex more than 0.5mm over the width of the cut out when tightened. The pane surface must be free of bumps and scratches that might affect the IP65 seal. The seal can be enhanced by the use of a silicon sealant if required.

2.4.4 Environmental Considerations Ensure that the PowerView CP OIT is installed correctly and the operating limits are followed (See Specifications). Do not operate the unit in areas subject to explosion hazards due to flammable gases, vapour or dust.



3. Electrical Installation

3.1 Connecting the PowerView Operator Interface Terminal 3.1.1 Power Requirements

Power The PowerView CP OIT.s can be powered by DC power only.

The specified voltage range varies from model to model, but is typically 24Vdc. See detailed specifications for exact details on the model you have purchased. The power conditioning circuitry inside the unit is accomplished by a switching power supply. The peak starting current can be as high as 700mA.

Cable Routing Always route the dc power cable and communications cable away from AC power cables, rapidly switching control signals and field cabling.

Fusing Requirements If the display does not come on within 2 seconds of power up, remove power. An internal fuse will prevent damage if the polarity of the DC power is incorrect. Check wiring to ensure proper connections and try to power up again.

Caution High Voltage

An internal fuse will prevent damage for over voltage condition however it isn’t guaranteed. DC voltage sources should provide proper isolation from the main AC power and similar hazards.

3.1.2 CE Requirements

To ensure the PowerView CP OIT complies with EMC directives and to reduce susceptibility to electrical interference, a separate 1mm2 ground wire should be taken into the Chassis Ground terminal of the power connector. This ground connection should be run directly to the central star earth connection point (as recommended in most Installation Instructions).

3.1.3 Grounding Requirements DC ground is not directly coupled to earth ground internally. It is preferable not to ground DC negative return to chassis ground as poor site earths can introduce noise into a system but if necessary an earth connection should be made from the power supply return point to the central star earth point. Ground conductors should be as short and as large in size as possible. The conductors must always be large enough to carry the maximum short circuit current of the path being considered. Ground conductors should be connected to a tree from a central star earth ground point. This ensures that no ground conductor carries current from any other branch.



3.2 Connecting the PowerView CP OIT Communications link. 3.2.1 Connecting the PT505A OIT Communications Link

The PowerView PT505A Operator Interface Terminal should be connected to the TR’s via the C6175A Powerterm Communications patch board, using a M1833A communications cable as shown in the connection diagram below.

3.5.4 Current and Voltage Monitoring on the L120P/R Extra Load terminals are provided on the L120P/>120R for monitoring purposes. Terminal voltage can be measured directly across the output load terminals. To monitor the load current, an internal shunt is provided across terminals 7(+) and 6(-). Output current can be monitored by monitoring the voltage across the shunt. This shunt is 25mOhms, and therefore the output current can be derived from the voltage measured across terminals 7 and 6 using the following formula:

3.6 Connecting the Powerterm C6333A MUX Boards Up to six C6333A MUX boards can be connected to a Powerterm LR90M Master CP Controller, providing the ability to monitor up to 90 reference half cells in the system. Each C6333A MUX board is connected to the LR90M via a M1837A patch cable. These cables are available in different lengths to suit the application. Locate the C6333A MUX boards close to the point of entry of the reference half cell field wiring to minimise the panel wiring. See Figure 1-1 Typical Powerterm CP System Configuration for typical connection diagram.

3.7 Connecting the Teleterm M2G If remote monitoring and control is required in the system, a Teleterm M2G must be installed. The Teleterm M2G is wired into the system as shown below:

3.7.1 Connecting the Serial Link The communications link from the Teleterm M2G to the CP system uses a Model C1833A RS232/485 Serial Communications Cable. Connect as shown below:

3.7.2 Mounting the Antenna The Teleterm M2G Remote Terminal Unit communicates remotely using a GSM wireless network. In most applications the GSM network reception at the site of the system should be adequate for reliable communications using the internal stub antenna supplied with the M2G. In remote locations with poor GSM reception it may be necessary to deploy an external higher gain antenna to ensure a reliable connection. A survey of the site is recommended to check reception. In most cases this would be limited to checking that a mobile phone enabled on the same network as that chosen for the Teleterm M2G and located in the position of the CP system panel shows reasonable reception. (The supplied M2G antenna is more efficient than the antenna of a typical mobile phone.)



4. Address Configuration

To enable the Powerterm LR90M CP Master Controller to communicate with each of the L120R T/R’s, each module must be given a unique address by setting the DIP switches on the side of each unit.

Figure 4-1 LR90M and L120x Address DIP Switch and Comms LED’s

The following table gives the DIP switch settings required for each device in the system:
