Step 6 - Connect external communications cables (if required)
See System Controller on page
and External Communications on page
SC100:
Connect RS232 communications cable to the front connector.
Ensure the cable is secured so that no force is applied to the RS232 connector as
this may damage the connector.
SC200:
Connect Ethernet and/or RS232 communications cables to the rear connectors:
1
Undo the retaining screw and partly withdraw the SC200.
2
Route the communications cable(s) from the SC200 position, through the APS to
the I/O panel cable access hole at the rear.
3
Connect the communications cable(s) to the connector(s) on the rear of the SC200.
RS232 connection access is restricted. If necessary, use a DB9 ribbon cable
extension (Farnell part number 869-6411 or similar).
4
Replace the SC200 and tighten the retaining screw.
For details on setup refer to Communications in the SC200 or SC100 Operation
Handbook. See Related Information on page

Task 5 - Connect the DC Load and Battery Cables
Step 1 - Connect battery cables
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.

2
Select battery cable to suit the battery circuit breaker (refer to following table).
3
Route the battery cables to the APS.
4
Terminate the battery live and common cable(s) with suitable crimp lugs (refer to
the following table).
5
Connect the battery common cable(s) on the common bar at the battery
termination points.
6
Terminate the battery live cable(s) at the battery circuit breaker terminal(s) and
tighten:
all 1/4" terminations to 3.9 - 4.5Nm (35 - 39 inch-pounds).
all 3/8" terminations to 18.7 - 21.9Nm (166 - 194 inch-pounds).
