VERIFY FIELD WIRING
The integrity of the field wiring shall be tested before installing field devices or landing the field wiring to the
system controller. With the end of each circuit open, the following tests shall be conducted:
1. Verify absence of ground-fault on any field wiring prior to connecting the circuits. Refer to
specifications for acceptable readings.
2. Verify no stray voltages exist on any field wiring prior to device installation.
3. Verify each conductor is free from shorts between all other conductors and chassis.
4. Measure wire resistance with a short across the circuit at a point furthest from circuit start. This is
typically across EOL for Class B and at the panel for Class A.
I
Caution
Field devices must not be connected if using a meggar or any
means that applies voltages in excess of device ratings to
prevent damage to the devices.
I
Caution
Do not proceed with the installation of electronic components
until the enclosure is completely free of dust and debris.

INSTALL THE AC POWER TRANSFORMER
System power supply transformers (Primary and Secondary) are installed within the control panel enclosure.
Threaded press studs are provided in the back of the enclosure for securing the transformers with the
supplied mounting hardware.
I
Caution
Before installing the transformer, make sure all
power (both AC and DC) has been removed.
The following general steps shall be used to install the transformer:
1. Locate the four threaded transformer mounting studs in the back of the enclosure as shown in
Exhibits 4-4 and 4-5.
2. Position the transformer over the mounting studs and secure in place with the four 6-32 hex nuts and
washers supplied. The transformer’s H1 and H2 (AC input) terminals shall be orientated to the left
side of the enclosure.
