Connecting the Mains Supply
Work carefully through the following steps (refer to the
figures on pages 12, 14, 18 and 19).
1. Locate the backup batteries in the housing 20.
2. Using the Jumper (supplied), connect the batteries
in series.
3. Observing the battery polarity, connect the battery
terminals to the wires 60.

If you are connecting 17 Ah batteries, you must re
-
place the wire 60 and jumper connectors.

ries; or similar with case flame class UL94-V2 (or
higher).
4. Connect the Earth wire to the [Q] terminal on the
terminal board 53.
5. Connect the Neutral wire to terminal [N], and the
Line wire to terminal [L] on the terminal board 53.

The Control panel will reset on power up.
!
DO NOT allow the power cable to cross over ot-
her wiring (see Figure 22a). The power cable
must be routed as per Figure 22c and held
firmly in place by a cable tie (see Figure 22b).

Thermal Probe
This Control panel supports the KST thermal probe.
The probe will optimize the battery charging process by
regulating the charge voltage in accordance with the
battery temperature.
Work carefully through the following instructions (refer
to the figure on pages 12, 14, 18 and 19):
1. Connect the probe 24 to the connector 38 on the
Main board of the Control panel.
2. Attach the probe to one of the batteries, in such a
way as to obtain optimum heat transfer.
3. Measure the Probe temperature.
4. Using the graph in Figure 23 and/or Table 3, find
the value (in accordance with the battery tempera
-
ture) that the output voltage of the Switching Power
Supply will be based on.
5. Using the trimmer 51, adjust the voltage on the ter
-
minal board 52 to the required value.
+
NOTE: to verify the battery efficiency, the PCB will
measure the internal resistance. In order for this
measure is not distorted, you should use only the
cables supplied; cables that are longer and have
an insufficient section may erroneously simulate
the condition of inefficient battery.
