Step 3 - Check terminations, secure cables and test insulation

Secure the cables with cable ties to ensure there will be no strain on the
terminals.
3
Test the insulation resistance of the cables.
Procedure complete
Task 6 - Install the Batteries
•
Always check that the battery cables have been terminated to the correct system polarity
BEFORE connecting the batteries or closing the battery disconnect device.
•
Connecting batteries to the system with incorrect system polarity will void all warranty
claims.
Installation procedure
Step 1 - Install the batteries
Follow the battery supplier's/manufacturer's installation instructions.
Step 2 - Connect Mid-point Monitoring sense wires (SC200 only)
The Mid-point Monitoring sense wires must have short-circuit protection fitted close to
the battery terminals. Use the Battery Mid-point Monitoring kits from Eaton (see Spare
Parts on page
) or equivalent.
1
Connect a Mid-point Monitoring sense wire to the middle interconnecting link on
each string of batteries (see following diagram).
Connect the wire from XH12A pin 1 to string 1, and so on.
If there are an odd number of 2V cells per string, then connect the sense wires to
the interconnecting link on the side of the central cell closer to the Common battery
terminal.
2
Tighten the terminals according to the battery supplier's/manufacturer's
installation instructions.
3
Insulate any un-connected sense wires.
4
Secure all sense wires to avoid any strain on the terminations.
