6.1 Maintenance Warnings
·
Service and repair should only be done by trained authorized personnel. During any service work to the
UPS, it should be turned off or manually bypassed. Note that potentially lethal voltages exist within this
unit as long as the battery supply is connected.
·
Your UPS power module and battery module(s) do not require routine maintenance. Do not open them
for any reason. There are no user-serviceable parts inside.
·
Even after the unit is disconnected form the mains, components inside the UPS system are still connected
to the battery packs which are potentially dangerous.
·
Before carrying out any kind of service and/or maintenance, disconnect the batteries and verify that no
current is present and no hazardous voltage exists on the terminals of high capacity capacitors such as
BUS-capacitors.
·
Fuses should be replaced only by factory authorized personnel. Blown fuses should be replaced only
with fuses of the same number and type.
·
Verify that no voltage between the battery terminals and the ground terminal is present before
maintenance or repair. In this product, the battery circuit is not isolated from the input voltage.
Hazardous voltages may occur between the battery terminals and the ground terminal.
6.2 Test, Replacement and Disposal of Batteries
The UPS does not require maintenance by the user, however, battery maintenance is recommended in
accordance with IEEE Recommended Practice for Maintenance, Testing and Replacement of
Valve-Regulated Lead-Acid (VRLA) Batteries for Stationary Applications (IEEE Std 1188-1996). When
the batteries expire, trained battery service personnel must replace them. A certified disposal/recycling
company should carry out disposal / recycling of the UPS and / or batteries. Exhausted rechargeable
batteries are classified as “harmful toxic waste” and as such the law demands that they be disposed of /
recycled by an authorized recycling center.
The manufacturer’s service center is fully equipped to deal with such batteries, in accordance with the law
and with the greatest respect for the environment. Contact Technical Support to arrange for maintenance
and/or battery replacement.
The typical battery life cycle is 3 to 5 years, at an ambient temperature of 77°F (25°C), however battery
life is also dependent on the frequency and duration of mains failures or battery discharge cycles.
The battery test should be carried out periodically (6 to 12 months) in order to ascertain the general
condition of the batteries.
6-2-1. Battery Replacement
WARNING:
Prior to starting the battery replacement, please read the entire instructions for important
safety procedures.
NOTE:
To obtain new battery(ies), contact POWERVAR Technical Services at 847-596-7000, toll free at
800-369-7179.
NOTE:
The UPS cannot protect against power outages while the batteries are disconnected.
