2-1 General

Inspect the controller for any shipping damage.

!

High voltage developed in the controller can cause
severe injury or death. Before servicing the unit,
disconnect the input power cable.

NOTE

The PCB installed into the customer system must be
positioned so that cold air (forced or natural convec-
tion) can flow through the PCB components

2-2 Line voltage selection

The controller can operates with two ranges of input
voltage:

– 120 Vac ±20%
– 220 Vac ±20%

The line voltage selection is done on the three pin male
connector on the primary wires of the transformer:

−

for 120 Vac connect the line wires as follows:

– 120 Vac to pin 2 (white)

– 0 V to pin 3 (bleu)

−

for 220 Vac connect the line wires as follows:

– 220 Vac to pin 1 (brown)

– 0 V to pin 3 (bleu)

NOTE

The mating connector and the female pins are provided

2-3 Power interconnections

The power supply from the external transformer must
be connected to J8 connector

See Fig. 2-1 for interconnections detail.
