4.2 Mounting instructions

Figure 3: Housing dimensions

Dimensions in milimeters.

All connections, module attachments and assembling must be done

while module is not connected to the main power supply.

Mounting instructions:

1. Switch OFF main power supply.

2. Mount LPC-2.VV1 module to the provided place inside an electrical panel (DIN EN50022-35

rail mounting).

3. Mount other LPC-2 modules (if required). Mount each module to the DIN rail first, then

attach modules together through K1 and K2 connectors.

4. Connect delta pressure pipes and actuator wires according to the connection scheme in

Figure 2.

5. Switch ON main power supply.

6. Green LED should turn on according to the able 5.

Dismount in reverse order. For mounting/dismounting modules to/from DIN rail a free space of at

least one module must be left on the DIN rail.

NO E: LPC-2 main module should be powered separately from other electrical appliance connected

to LPC-2 system. Signal wires must be installed separately from power and high voltage wires in

accordance with general industry electrical installation standard.
