Power Wiring

The InterOP8500 module is designed to

accept power directly from either the

PWRSUP8500 or the existing Johnson power

supply (LPS-105 and RPA-105). In order to

retain the UL listing of your system, a field

inspection is required if using a Johnson

power supply or the RPA-105 and the LPS-105

must be replaced by the PWRSUP8500 or.

Refer to "Using the ALC Power Supply" on

page 6 for wiring with the PWRSUP8500, or to

"Using the Johnson Power Supply" on page 7

for wiring with an existing Johnson power

supply.

Revised 7/10/01 • InterOP8500

Whenever possible, make sure the module's

1's

power and communications connections are

working properly before connecting any

inputs and outputs. Care should be taken to

isolate power wiring from all other wiring

inside the enclosure. The high and low

voltage wiring must be kept as far apart from

each other as is possible to avoid noise

interference.

NOTE To protect analog signals from stray

NOTE

noise and to minimize EMI, use shielded

cable on all signal wires and low voltage

power wires.

When entering, exiting, or interconnecting

with the enclosure, it is better to use several

small openings than one large one. The 12V

binary outputs are powered by a separate

source supplied through the field termination

board.

CAUTION The InterOP8500 module is a

CAUTION

Class 2 device (less than 30VAC.) Take

appropriate isolation measures when

mounting an InterOp8500 module where

non-Class 2 devices or wiring are present.
