Step 1
Place the Battery Pack close enough to the Inverter/Charger so that the Battery
Pack's cables can reach.
Step 2
Place the Inverter/Charger's operating mode switch in the "OFF" position. Make
sure the Inverter/Charger is unplugged from and/or not receiving power from any
AC source. Make sure the Inverter/Charger is disconnected from any DC power
source.
Step 3
Remove the half-inch of insulation on each
of the wire ends of the red battery connector
that is included separately with the
BP12V81 Battery Pack. Connect the red
battery connector's wire ends to the
Inverter/Charger's DC terminals. Connect
the RED wire to the Inverter/Charger's
POSITIVE (+) DC terminal. Connect the
BLACK wire to the Inverter/Charger's
NEGATIVE (-) DC terminal.
WARNING!
Failure to observe proper polarity dur-
ing connection could damage and void
the warranties of both the BP12V81
Battery Pack and the Inverter/Charger.
Securely tighten the Inverter/Charger's DC terminals to prevent the red battery
connector's wires from coming loose due to accidental stress or tension.
Step 4
Take the Inverter/Charger's red battery
connector (A) and connect it to the red
battery connector located at the end of
the longer of the two cables on the
BP12V81 Battery Pack (B).* The two
connectors can only be joined with one
orientation and should snap into posi-
tion when pressure is applied.
* Note: There are two cables located on the Battery
Pack: a long cable and a short cable. The long cable
is for connecting to the Inverter/Charger (or to an
additional Battery Pack in an optional daisy-chain
connection, see below). The short cable is only used
in an optional daisy-chain connection (see below);
otherwise, the short cable will remain unconnected.
Optional Daisy-Chain Connection (for longer runtime)
For longer runtime, daisy-chain two or more BP12V81 Battery Packs together. Take
the daisy-chain cable, the shorter cable (A), of the Battery Pack closest to the
Inverter/Charger and connect it to the external battery connector cable, the longer
cable (B), of the Battery Pack you want to add. Repeat the procedure for each
additional Battery Pack you connect.
Step 5
Restore AC power to the Inverter/Charger. The BP12V81 Battery Pack(s) and
Inverter/Charger are now connected and ready to be used for battery backup
applications.
Step 6
Set the Inverter/Charger's Configuration DIP Switches to the following positions.
Note: the diagram represents the RV750UL and similar Inverter/Chargers. Select
Inverter/Charger models do not include the B4, B3, B2 and B1 DIP Switches; in
these cases, simply make the A4, A3, A2 and A1 settings recommended below.
Switch Position Configuration
B4 UP Low Charge Amps
B3 UP Equalize Battery - Leave in up position
(Refer to Owner's Manual)
B2 DOWN B1 in up position and B2 in down position—Limit charging
of the battery pack to 66% of the full load rating of the unit
B1 UP
A4 UP A3 and A4 both in up position—Unit will switch to battery
backup when AC input voltage drops below 105VAC
A3 UP
A2 DOWN Battery Charger Enabled
A1 UP Gel Cell (Sealed) Battery
