Section D Section E
1. Section A: Inverter communication
ports
a) First, connect the enable ground
wire to Terminal 2.
b) Connect the enable 12V positive
line to Terminal 1.
c) Select the method that matches the
inverter communication method
in the part marked. If the inverter
uses RS485, connect the RS485
(A+, B-) lines to Terminals 3 and 4.
If inverter uses the CAN method,
connect the CAN (high, low) lines
to Terminals 5 and 6.
2. Section B: DIP switch for setting
communication termination resistor
of primary/secondary packs
Lower the DIP switch (Communication
Termination resistor) all downwards for
single pack.
※ When you install two packs, refer
to the appendix about setting for
communication termination resistor.
3. Section C: DIP switch for setting
primary/secondary packs
Raise all DIP switch upward when
you want to use as a primary pack.
And also, when you want to use as a
secondary pack, lower the switch on
the right side only when viewed from
the front

※ Peel cable sheaths (15 mm for the power terminal cable and 10 mm for the communication
terminal cable).
NOTE
Check all cable are firmly in place. Loose power cables can cause arcing and may damage
the battery and/or inverter.
4. Section E: Battery power port
a) Connect the ground wire to
Terminal 2.
b) Connect the negative line of the
power cable to Terminal 3.
c) Connect the positive line of the
power cable to Terminal 1.
※ Refer to 3.3.3 Spring Terminal
Blocks when choosing the battery
power cable and cable sheath for
peeling.
