7.4 Replacing or adding Battery Packs
You can expect to receive 3 to 6 years of service life from the Battery Packs when
installed in a cool, dry location. The Battery Pack's life is shortened when operated in
an environment where the ambient temperature is normally above 30°C (86°F).
The Electronics Unit will display this message when any
one of the connected Battery Packs requires replacement.
Battery Packs that can no longer sustain a charge are
identified by an illuminated Replace Battery indicator.
Battery Packs can be added or replaced at any time, regardless of mode of operation.
See the procedures listed below to replace a worn Battery Pack.
Caution: If the first Batter y Pack in the string (connected directly the Electronics Unit)
is replaced, the UPS will not be able to support the load in the event of a mains failure
during the time that the battery string is uncoupled from the EU. Always place the UPS
in bypass when this Battery Pack is replaced.
7.4.1 Disconnect both INPUT and OUTPUT battery communications cables con-
nected at the worn Battery Pack.
7.4.2 Remove the clamps securing the in-line coupler and panel coupler (if neces-
sary) at the worn Battery Pack.
7.4.3 Unmate the couplers at the worn Battery Pack and return it to the factory for
recycling.
7.4.4 If necessary, remove the panel coupler clamp. Set the new Battery Pack in
place.
7.4.5 Mate the in-line and panel couplers on the new Battery Pack.
7.4.6 Secure the couplers with the coupler clamps.
7.4.7 Plug-in the battery communications cables at the new Battery Pack. See the
illustration in Section 4.10.6.
Note: Always check the number of Battery Packs reported
by the UPS (UPS Status menu) after adding or replacing
Battery Packs.
Note: If this fault message is encountered, check the
communications cables to, and from each Battery Pack
see Section 4.10.6.
