5.2 Connecting the Power Cables

See Sections 1.6 and 1.7 Specifications for details about the BM85 operating power and connector requirements.

Caution:You can connect power cables to the BM85 but ensure that the power is OFF before connecting the network or serial cables to the unit

AC/DC Models

AC/DC models are supplied with a power cable of 6 ft (2 m) length for operation from 110-120 Vac or 220-240 Vac single-phase power. The cable connects to a socket on the rear panel. Grounding is through the cable. The ac line switch is located on the rear panel. The BM85 contains an ac line fuse that is accessible on the rear panel.

All of these models except the BM85-000 can also operate from an external 24 Vdc source. Power connects to a socket on the rear panel. Grounding is through the cable. The dc source must be switched and fused externally to the BM85.

DC/DC Models

DC/DC models operate from a 125 Vdc or 24 Vdc source. Power connects to a terminal strip on the rear panel. A grounding terminal is provided. The dc source must be switched and fused externally to the BM85.

5.2.1Connecting AC Power

Set the BM85 power switch to the `0' (power OFF) position. Connect the BM85 to the power source. Set the power switch to `919' (power ON). The unit's POWER indicator should illuminate.

Before connecting the network cables, set the power switch to the `0' (power OFF) position. The unit's POWER indicator should not be lit.

5.2.2Connecting DC Power

Set the external dc power source to OFF. Connect the BM85 to the source. Set the dc power source to ON. The BM85 unit's POWER indicator should illuminate.

Before proceeding with the connection of the network cables, set the dc power source to OFF. The unit's POWER indicator should not be lit.
