saturation point. The relay module inside the panel is designed to operate in a maximum 85 percent relative humidity continuous, non-condensing, moisture environ-ment.
VibrationDo not install the panel where it could be subjected to vibra-
tion in excess of 0.5G continuous maximum vibration.
GeneralOverall panel size: 24in. high x 24 in. wide x 8 in. deep
(excluding door and door mounted components)Panel weight: approx. 75 poundsMounting holes are 0.44 in. typical diameter, 18 in. on center.
ApprovalsComponents are individually approved by the nationally rec-
ognized agencies. Please see component literature for details. The panel has UL 508A approval. Panel is assem-bled and wired to the UL Standards.
INSTALLATION
When Installing This Product…1. Read these instructions and the appropriate product lit-
erature carefully. Failure to follow them could damage the product or cause a hazardous condition.
2. Refer to the installation manuals and wiring diagrams provided with this panel for the embedded products.
3. Read these instructions and the appropriate product lit-erature carefully. Failure to follow them could damage the product or cause a hazardous condition.
4. Refer to the installation manuals and wiring diagrams provided with this panel for the embedded products.
5. Check the ratings given in the instructions and on the product to make sure that the product is suitable for your application.
6. Installer must be a trained, experienced combustion ser-vice technician.
7. Disconnect the power supply before beginning installa-tion to prevent electrical shock and equipment dam-age. More than one disconnect may be involved.
8. All wiring must comply with the National Electric Code (NEC) and any applicable local electrical codes, ordi-nances and regulations.
9. After installation is complete, check out product opera-tion as provided in the appropriate product installation instructions.
WARNINGFire or Explosion Hazard. Can cause severe injury, death or property damage.To prevent possible hazardous burner operation, verify safety requirements each time a controller is installed on a burner.
WIRING
WARNINGElectrical Shock Hazard. Can cause serious injury, death or equipment damage.Disconnect the power supply before beginning wiring to prevent electrical shock, equipment and control damage. More than one disconnect may be involved.
Ground ConnectionEarth ground is required for proper operation of the panel and components. The earth ground must be capable of conducting enough current to blow the fuse or breaker in the event of an internal short. Ensure the panel is bonded to a substantial earth ground. Make sure that mechanically tightened joints along the ground path are free of nonconductive coatings and protected against corrosion on mating surfaces.
Electrical Connections1. Refer to the appropriate product data sheet for details.2. Wire size and length will vary, depending on the compo-
nent. Refer to the component literature for specific wire lengths, sizes and type recommendations.
3. Wire according to specifications, following all local ordi-nances and requirements.
4. Field knockouts are required for the wiring. When drill-ing holes, take care to protect the electronics from metal pieces and debris.
IMPORTANTRun line voltage and low voltage wiring in separate conduit to avoid signal interference.
Carefully check field wiring and terminal designa-tions in this document and the associated wiring dia-gram. They are different from those of the individual components.
Panel InspectionAfter mounting and wiring, but before powering the panel, inspect all internal panel wire connections. Wires may loosen during transit. Verify that all internal wire connections are secure from the wiring subbases to the components mounted on the door and the S7999D touchscreen interface.
Final Wiring Check and Static CheckoutAll wiring shall be in accordance with the National Electric Codes (NEC) and local electrical codes.
1. Check the power supply circuit. The voltage and fre-quency must match the specification listed.
2. Check wiring terminations and routing to ensure proper connections.
3. Follow any system checkout recommendations for indi-vidual components as found in the component literature.
4. Restore power to the panel.

CAUTIONTest each limit and interlock to ensure system operates correctly as defined in the 7800 Series “Checkout and Test” document (Form #65-0229).
WARNINGExplosion and Electrical Shock Hazard. Can cause serious injury, death or equipment damage.
1. Close all manual fuel shutoff valves before starting these tests.
2. Use extreme care while testing the system. Line voltage is present on most terminal connections when power is on.
3. Replace all limits and interlocks that are not operating properly. Do not bypass limit and interlocks.
TROUBLESHOOTING
System DiagnosticsThe S7999D touchscreen interface indicates the current fault and keeps a fault history log. The RM7800L control also has LED fault blink codes. The DC controls have various tests and status messages. Refer to the appropriate product instruction sheet for further troubleshooting information and diagnostic codes.

FIELD WIRING
1 Carefully check field wiring and terminal designations in this document and the associated wiring diagram. They are different from those of the individual components.
2 The circuit protection incorporated into this control panel is designed to serve as supplemental protection only. It is the respon-sibility of the end user to provide appropriate protection on the service to this control panel. Refer to the National Electric Code and UL standard 1077 for more information on this subject.

3 Jumper all unused limits, interlocks and valve proof of closure switches.4 Refer to the appropriate flame detector product sheet for wiring size and length information. Run flame detector F and G leads
in their own conduit, independent of other power carrying leadwires. Flame detector power and shutter wires (if applicable) must be run in their own conduit as well, avoiding other electrical noise carrying wiring. The scanner wires should remain sep-arated a minimum of 2 inches from other line voltage wires in the control panel to the flame safeguard device.
5 Refer to the appropriate ignition transformer product sheet for wiring size and length information. Separate the high voltage ignition cable from other wires to avoid interference. Ignition cable to the spark electrode must be run in separate conduit (if applicable).
6 If VPS (Valve Proving System) usage is required with the RM7800 burner control, contact factory for advice regarding wiring.7 For high temperature limit, wire Type K thermocouple + input (yellow) to + terminal and - input (red) to - terminal. For pressure
limit, supply appropriate transmitter and program DC2500 controller for pressure operation. Thermocouple or transmitter wires must be run in separate conduit with other low voltage wires to avoid signal interference. DC2500 controls from the factory are set-up for temperature, but can be modified in the field for pressure operation.
8 Firing rate control output is 4-20mA. A 4-20mA firing rate/modulating actuator should be used with this panel. Run actuator low voltage field wire in separate conduit with other low voltage wires to avoid signal interference. Motor may be powered from panel T4 (L1) and T2 (L2) or separately.
9 COM 2 on the S7999D is wired in a daisy-chain fashion to the S7810M Modbus module on the RM7800L burner control and the UDC2500 controls in the panel for display on the S7999D. Customer may wire other Modbus-enabled UDC2500/3200/3500 controls in a daisy-chain fashion to the customer terminals provided for display on the S7999D. Refer to the S7999D and UDC control product manuals for further information on wiring and S7999D display set-up
10Installation, operation and maintenance shall conform with National Fire Protection Association standards, national and local codes and authorities having jurisdiction.
11For detailed device wiring information, refer to the RM7800, Q7999, S7999D1048 and DC2500 product sheets.12Spare/unused terminals are provided for customer field use.
