— C. Install Intrabay & Interbay Cabling

The input -48 and RTN plates contain mounting holes for bus extensions to other panels in the same bay. Telect has busing and cabling kits for all types of input extensions.

— D. Install Alarm Cabling

External indicators (monitors) can be connected to the BDFB / BDCBB alarm board. The external indicators can be wired to accept either a normally open or closed circuit when the VDC PWR or FUSE ALM LEDs or other optional alarms are activated.

To connect power- and fuse-alarm circuits to the BDFB / BDCBB, proceed as follows:

1.Refer to the following illustration and then remove four Phillips screws (screws with cross-recessed heads) securing alarm panel.

2.Carefully pull off and turn alarm panel cover around.

3.Strip off ¼ in. of insulation on end of a pair of 18-24 AWG alarm wires for each external alarm circuit desired.

4.Select a common (C) contact and either a normally closed (NC) or normally open (NO) contact for each alarm desired:

•For a C and NC pair, expect continuity (0 Ω) during normal operation and an open circuit (∞ Ω) for an alarm condition such as an open breaker or a power failure.

•For C and NO pair, expect an open circuit (∞ Ω) during normal operation and continuity (0 Ω) for an alarm condition such as an open breaker or a power failure.
