Wiring Considerations
•
Recommended Practice for Powering and Grounding
Sensitive Electronic Equipment (IEEE Emerald Book)
,
ANSI/IEEE 1100.
•
Recommended Practice for Grounding of Industrial
and Commercial Power Systems (IEEE Green Book)
,
ANSI/IEEE 142.
Do not attempt to install any system or related equipment
before consulting and understanding these documents as well
as any other applicable international standards.
The auxiliary terminal uses color coded wire. Table 3-1 lists
the wire colors and their respective signals.
AC Power Wiring
The AC power input connects to a terminal block on the PEP.
The auxiliary terminal operates from 120/240 VAC, 50/60
hertz. The PEP provides line filtering, transient suppression
and a 20-amp circuit breaker.
In addition to AC input terminals, the PEP has alarm relay out-
puts located on a terminal block and cable connectors for
peripheral devices. Note that the alarm relay outputs are for
alarm annunciation only.
Setting up the auxiliary terminal for 240-VAC requires that the
voltage selector switch on the CPU be in the proper position.
Refer to Procedure
