Communications option

Connection of the communications option

None of the control-unit protection functions require an auxiliary source. However, the 24 V DC external power-supply (AD module) isrequired for certain operating configurations as indicated in the table below.

Communications option no no noM2C, M6C programmable contacts option yes yes yesProtection function no no noDisplay function no (1) no (2) yesTime-stamping function no no yes (3)

(1) except for Micrologic A control units (if current < 20% In).(2) except for Micrologic A control units.(3) time setting is manual and can be carried out automatically by the supervisor via the communications bus.

The communications bus requires its own 24 V DC power source (E1, E2). This sourceis not the same as the 24 V DC external power-supply module (F1-, F2+).The BAT battery module, mounted in series upstream of the AD module, ensures anuninterrupted supply of power if the AD module power supply fails.The voltage measurement inputs are standard equipment on the downstreamconnectors of the circuit breaker.External connections are possible using the PTE external voltage measurement inputoption. With this option, the internal voltage measurement inputs are disconnected andterminals VN, V1 and V2 are connected only to the control unit (Micrologic P and H only).The PTE option is required for voltages less than 100 V and greater than 690 V (in whichcase a voltage transformer is required). For three-pole devices, the system is suppliedwith terminal VN connected only to the control unit (Micrologic P and H).When the PTE option is implemented, the voltage measurement input must be protectedagainst short-circuits. Installed as close as possible to the busbars, this protectionfunction is ensured by a P25M circuit breaker (1 A rating) with an auxiliary contact (cat.no. 21104 and 21117). This voltage measurement input is reserved exclusively for thecontrol unit and must not ever be used to supply other circuits outside the switchboard.

Earth-leakage protection

A pilot wire interconnects a number of circuit breakers equipped with Micrologic A/P/Hcontrol units, as illustrated in the diagram above.The control unit detecting a fault sends a signal upstream and checks for a signalarriving from downstream. If there is a signal from downstream, the circuit breakerremains closed for the full duration of its tripping delay. If there is no signal fromdownstream, the circuit breaker opens immediately, whatever the tripping-delay setting.Fault 1.Only circuit breaker A detects the fault. Because it receives no signal from downstream,it immediately opens in spite of its tripping delay set to 0.3.Fault 2.Circuit breakers A and B detect the fault. Circuit breaker A receives a signal from B andremains closed for the full duration of its tripping delay set to 0.3. Circuit breaker B doesnot receive a signal from downstream and opens immediately, in spite of its trippingdelay set to 0.2.

Mounting position

Power supplyMasterpact devices can be supplied either from the top or from the bottom withoutreduction in performance.

Installation in switchboard

Mounting the circuit-breakerIt is important to distribute the weight of the device uniformily over a rigid mountingsurface such as rails or a base plate.This mounting plane should be perfectly flat (tolerance on support flatness: 2 mm).This eliminates any risk of deformation which could interfere with correct operationof the circuit breaker.Masterpact devices can also be mounted on a vertical plane by the use of brackets(optional extra).

Mounting with vertical brackets.

Mounting on rails.

Busbars connectionsThe busbars should be suitably adjusted to ensurethat the connection points are positioned on theterminals before the bolts are inserted (B)The connections are held by the support which issolidly fixed to the framework of the switchboard, suchthat the circuit breaker terminals do not have tosupport its weight (C).

Cables connectionsWhen cable connections are required it is important toensure that no excessive mechanical forces areapplied to the rear terminals.

It is recommended that connections are made asfollows:c Extend the circuit breaker terminals using short

bars designed and installed according to therecommendations for bar-type power connections:

v For a single cable, use solution B opposite.v For multiple cables, use solution C opposite.

c In all cases, follow the general rules forconnections to busbars:

v Position the cable lugs before inserting the boltsv The cables should be firmly secured to the

framework of the switchboard.
