Power supply module
Installing the power supply module
The mains power connection may be connected to the power supply module only by an authorized electrician. A readily accessible disconnect device shall be incorporated in the fixed wiring (IEC 950).
Remove the plastic plug in the transmitter housing and replace it with the cable gland. Fasten the power supply module to the bottom of the housing with four screws; select the correct mains voltage with voltage selector switch (230/115).
Attach the grounding wire screw and washer to the grounding terminal on the right-hand side of the module. Attach the wires from the power supply module to the power terminal on the main board of the transmitter.
NOTE The jumper in connector X3 has to be in position ON; otherwise no power is supplied to the transmitter.
When the power supply module is on, the power on LED is lit.
