Battery Maintenance Guidelines
The battery maintenance instructions listed below are for reference only. Battery manufacturer’s instructions for
transportation, installation, storage or maintenance take precedence over these instructions.
• To prevent damage, inspect batteries every three months for:
Signs of battery cracking, leaking or swelling.
The battery should be replaced immediately by authorized
personnel using a battery of the identical type and rating.
Signs of battery cable damage.
Battery cable should be replaced immediately by authorized personnel
using replacement parts specified by vendor.
Loose battery connection hardware.
Refer to battery manufacturer’s documentation for the correct torque
and connection hardware for the application.
• Apply battery manufacturer’s specified antioxidant compound on all exposed connections.
• Verify battery terminals or exposed connection hardware is not within close proximity of a conductive surface.
Reposition batteries as necessary to maintain adequate clearance.
• Clean up any electrolyte (battery emission) in accordance with all federal, provincial (or state), and local
regulations or codes.
• Proper venting of the enclosure is recommended. Follow the battery manufacturer’s approved transportation
and storage instructions.
• Always replace batteries with those of an identical type and rating. Never install old or untested batteries.
• Do not charge batteries in a sealed container. Each individual battery should have at least 12.7mm (0.5”) of
space between it and all surrounding surfaces to allow for convection cooling.
• All battery compartments must have adequate ventilation to prevent an accumulation of potentially dangerous
Recycling and Disposal Instructions
Spent or damaged batteries are considered environmentally unsafe. Always recycle used batteries or dispose of
the batteries in accordance with all federal, provincial (or state) and local regulations.
• Lethal voltages are present within the power system. Never assume that an electrical connection or conductor
is not energized. Check the circuit with a voltmeter with respect to the grounded portion of the enclosure (both
AC and DC) prior to any installation or removal procedure.
• Always use the buddy system when working under hazardous conditions.
• A licensed electrician is required to install permanently wired equipment.
• Ensure no liquids or wet clothes contact internal components.
• Hazardous electrically live parts inside this unit are energized from batteries even when the AC input power is
• For cord connected model, the plug is the disconnect device. A socket outlet shall be installed near the
equipment. For hardwired model, a breaker shall be used for a disconnect device. For IEC line cord option,
the inlet on the cord is the disconnect device for such systems.
DOUBLE POLE/NEUTRAL FUSING:
For continued protection against risk of fire, replace only with the same type and rating of fuse.
