1. Operate the toggle of the BATTERY CIRCUIT breaker to the OFF position, then

Section 8: Options
The Blackhawk Series power supplies support several optional features appearing in
the following list. The options and accessories listed enhance the usefulness of your
power supply as aids to installation and servicing and are available through Multilink
Broadband as extra-cost items.
Cabinet Indicators:
Power supplies documented in this manual support external alarm lamps mounted in
the power supply enclosure which act as a simple form of status monitoring. A red lamp
located on the external enclosure will illuminate to indicate operation from battery
reserve during a commercial AC power failure, or a failure condition in the batteries or
power supply that requires corrective action. Normal operation without any alarm
conditions is indicated by illuminating a green lamp only.
Battery Cable Kits:
Designed for 3, 4, 6, or 8-battery powering applications.
Remote Indicator Harness (30 inch):
Designed for use with custom remote indicator systems.
Output Cable:
28-inch unterminated cable adapts the UPS for use in a wide variety of existing
enclosures.
Status Monitoring:
The optional HMS Status Monitor may be installed in any Blackhawk Series power
supply. This method of status monitoring supports communication between the power
supply and an external transponder device via an RS-485 serial port as described in
ANSI/SCTE 25-3 2002 (HMS-022) Standard.
An optional HMS-to-Legacy converter may be installed which enables the conversion
of serial digital data into analog format. The analog output enables power supply
monitoring through the use of older types of status monitor equipment.
