CONNECTING THE CONTROL UNIT TO AN AC OUTLET

POWER TO THE SYSTEM

A properly grounded outlet protects the system against damage from power surges and other disturbances. Refer to “System Grounding Requirements” on page 2-5. The outlet should be 117-volt, 60-Hz, third wire grounded. To ensure proper operation of the system, the ac outlet should be connected to earth ground.

NOTE: Do not connect the control unit to a switch controlled outlet. Accidental disconnection and loss of data may occur.

Perform the following steps to connect the control unit to an ac outlet:

1Make sure the power switch on the Power Supply Module is in the OFF position. If there is an expansion power supply, turn it off also. If the system has any Auxiliary Power Supplies, make sure that they are unplugged from the ac outlet.

2Plug one end of the power cord into the connector just below the power switch on the front of the Power Supply Module labeled “AC INPUT.” Do this for each carrier.

3If the system has one or more Auxiliary Power Units, see “Installing the Auxiliary Power Unit” on page 2- 72.

4Plug the other end of the power cord into the ac outlet, allowing for at least 1 foot of slack.

CAUTION: Do not attach the power cord(s) to the building surfaces.

When the system is completely installed and ready to be powered-up, follow the sequences described below to apply or remove power.
