When Adding Additional Power Supplies

When a new power supply needs to be added:

Typically, a new power supply is needed after every sixth OP or when a run goes to a

different floor. The correct wiring method is described below in diagram form.

Example: Power Zone 1: OPs 1-6 (one power supply)

Power Zone 2: OPs 7-12 (two power supplies)

Power Zone 3: OPs 13-18 (three power supplies)

Etc.

Wiring Between Power Zones:

1. Wire the sixth OP to the seventh OP using only the ground (negative or

conductor) wire. DO NOT CONNECT THE POSITIVE WIRE.

2. Use this method to tie all grounds between power zones.

3. Add additional power supply and install 16/2 from power supply low voltage side

into OP in +/- maintain polarity!

NOTE: Be sure grounds are run between power zones.
