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.

Task 7 - Mount the Battery Temperature Sensor
The APS is supplied with a battery temperature sensor and standard 2m (6.5 feet) long cable,
already connected to the IOBGP input/output (I/O) board to measure the ambient air
temperature around the batteries. This is required for the temperature compensation control
process.
Step 1 - Connect and route cable
1
Connect the temperature sensor cable supplied to socket XH7 on the I/O board.
If required extend the cable using an RJ45 patch cable and in-line joiner.
Recommended maximum cable length is 20m (65 feet) because of noise
considerations.
2
Route the temperature sensor cable to the middle battery shelf or the middle of
the external battery stand.
Do not run the sensor cable along ac supply cables. Interference may cause false
readings.
