for the appropriate fasteners, (plastic anchors, molly
bolts, screws, etc.)
5. Remove the necessary knockouts for the wire or
conduit entry before mounting the panel.
6. Place the enclosure back onto the surface and secure it
with the appropriate screws.
7. Follow Step 5 in the previous section to replace the
microprocessor within the enclosure.

WARNING
Proper Field Wiring and Grounding
Required!
Failure to follow code could result in death or serious
injury.
All field wiring MUST be performed by qualified
personnel. Improperly installed and grounded field
wiring poses FIRE and ELECTROCUTION hazards. To
avoid these hazards, you MUST follow requirements
for field wiring installation and grounding as
described in NEC and your local/state/national
electrical codes.
WARNING
Hazardous Voltage w/Capacitors!
Failure to follow instructions below could result in
death or serious injury.
Disconnect all electric power, including remote
disconnects and wait for DC capacitors to discharge
before servicing. Refer to the manufacturer’s
recommendations for proper discharge time as DC
bus capacitors retain hazardous voltages after input
power has been disconnected. Follow proper lockout/
tagout procedures to ensure the power cannot be
inadvertently energized. Verify with a CAT III or IV
voltmeter rated per NFPA 70E that all capacitors have
discharged before touching any internal components.
The remote human interface requires 24 VAC + 4 volts
power source and a shielded twisted pair communication
link between the remote panel and the interprocessor
communication bridge (ICPB) module at the self-contained
unit.
Field wiring for both the low voltage power and the shielded
twisted pair must meet the following requirements:
Important: To prevent control malfunctions, do not run low
voltage wiring (30 volts or less) in conduit with
higher voltage circuits.
• All wiring must be in accordance with NEC and local
