2. External Battery Connection
When using an external battery, provide the following connections.
Notes
:
1. One battery pack is required for each 4-PIM stack, to ensure that sufficient recharge current is
available.
2. The capacity of each external battery is determined by the customers’ back-up requirements.
3.
CAUTION: For both sealed and vented batteries, set the “mode” switch on the PZ-PW86/PZ-
PW86(A) unit(s) to the correct Float Voltage. The “Equalize” option applies ONLY to external
vented batteries for periodic equalize (BOOST) charging, which can be done on-line. When the
BATTM is used, the battery capacity is in multiples of 26 A-H, up to a maximum of three sets in
parallel for each PIM stack.
