DC INPUT

The DC input accepts input voltages from 36 to 60 VDC. An indicating fuse is included which exposes a marker if the fuse is

blown. If the fuse requires replacement, ensure the voltage and current rating is correct. The fuse type is a 10 Amp, 125VDC

indicating telecom-style fuse. Suggested part numbers are Bussman GMT-10 or Littlefuse 0481010. The fuse mounts with the

indicator to the right. The DC power switch may be used for turning the power on and off to the entire chassis.

ALARM

This connector is used for an external alarm monitor. It is an 8-pin miniature circular connector. The indicated pins are

connected to a dry-contact relay that is active when an alarm is present in the chassis. See Table 4.1A and Diagram 4.1B for

the connector pin descriptions.
