Introduction
This guide illustrates installation of the Sensor

minutes during power outages, thereby facilitating an instantaneous recovery after power has
been restored. Each Battery Backup Unit may be fitted with one or two batteries; each battery
feeds one Sensor3 rack.
Required tools:
• Slotted screwdriver
• Precision slotted screwdriver
• No. 2 Phillips screwdriver
• Small extension (dental) mirror
• Wire strippers for 14-18 AWG (1.5-2.0mm
2
) wire
• Wire cutters
Required materials (not provided):
• Appropriate mounting hardware for attaching unit to wall
• 14-18 AWG (1.5 - 2.0mm
2
) twisted pair of adequate length for wire run
• 3/4” or smaller conduit of adequate length for wire run
• Conduit sleeves (2)
Procedure
This procedure is broken down into the following subsections:
Install Conduit from Unit to Sensor3 Rack on page 2
Connect the Battery Leads on page 2
Run Wire from Unit to Rack on page 3
Install Battery Pack(s) on page 4
Preparation
Step 1:
Turn off power to the rack. Before removing dimmer or control modules for
service, de-energize main feed to dimmer rack and follow appropriate Lockout/
Tagout procedures as described in NFPA Standard 70E. It is important to note
that electrical equipment such as dimmer racks can present an arc flash safety
hazard if improperly serviced. This is due to available large short circuit
currents on the feeders of the equipment. Any work on energized equipment
must comply with OSHA Electrical Safe Working Practices.
W A R N I N G :
RISK OF ELECTRIC SHOCK! Failure to disconnect all power to the rack
before working in the rack could result in serious injury or death.
