3. Battery Cabinet Installation

3.6 Battery Cabinet Placement

Place the battery cabinet in a cool location with free airflow and away from direct heat sources. The lifespan and performance
of a battery may be dramatically affected by elevated temperature, decreasing 50% for each 8.25° C above 25° C.
1. Prepare the surface where the cabinet will be placed. The surface must be clean, flat and able to support the battery
cabinet and other equipment installed nearby. See section 7. Specifications for floor loads.
2. Allow adequate clearance around the front and rear of the battery cabinet for ventilation and maintenance. The front door
must be accessible to allow easy access to internal batteries, internal fuses and other overcurrent protection devices. See
section 5.1 Unpacking and Inspection for dimensions and battery cabinet measurements.
3. If the cabinet will be anchored to the floor, install appropriate anchor bolts in the mounting hole located at the bottom of
the cabinet. Use washers to create a level surface between the mounting areas around the anchor bolts.
4. Using extreme caution, remove the bolts securing the battery cabinet to the shipping pallet.
5. Forklift forks should be at maximum width within the cabinet clearance opening and fully inserted to prevent tipping. Lift
cabinet from bottom only. Be careful not to damage the sheet metal floor of the cabinet with the forks.
6. If the battery cabinet will be secured to the floor, carefully align and lower the battery cabinet down on the floor anchor
bolts and secure it in place.
7. If the cabinet will not be secured to the floor, lower it into the designated space and then level it using shims. Leveling does
not affect performance, but does align the battery cabinet with other equipment in the facility.

3.7 Electrical Connection

DANGER! LETHAL HIGH-VOLTAGE HAZARD!
All wiring should be performed by a qualified electrician in accordance with the warnings in this manual and
all applicable electrical and safety codes. Incorrect wiring may cause serious personal injury and property
damage.
• The battery cabinet is connected to the load through a DC circuit breaker. This allows the battery to disconnect from the load
and charger for maintenance and/or repair.
• The DC molded case circuit breakers are CE-approved for branch circuit protection. If replacement is required, CE-approved
components with the same voltage and current rating must be used.
• The size of the load connection cables must consider maximum allowable voltage drop, as well as the cables' continuous
ampere capacity and anticipated ampere discharge rate of the individual battery cabinet. A maximum voltage drop of 1.5V
DC in the load connection cables is recommended. Refer to the UPS unit's Owner's Manual for recommended wire sizes.
• Refer to all applicable local, state and national codes for appropriate cable size and ratings.
• External circuit protection devices (fuses or circuit breakers) must consider the discharge rate of the battery, the wiring to be
protected and the DC short circuit current of the battery.
After performing the installation procedures in section 5. Installation, perform the following:
1. Open the front door of the battery cabinet to access internal components. Use a digital voltmeter when voltage
measurements are required.
2. Determine if the battery has been inadvertently grounded by resetting the circuit breaker to the "On" position and
measuring the voltage between the battery cabinet grounding lug and the positive load connection point within the cabinet.
This voltage should measure 0 (zero) VDC. If the measured voltage is not zero, determine the cause and correct before
proceeding.
3. Return the internal circuit breaker to an open "Off" position as a safety precaution while connecting the output cables.
Doing so prevents damage in the event the cables are accidentally shorted.
