Step 3: Connect all wired devices
Connect all wired devices except the battery, as shown in Figure 14. If you are using a
plug-on module, fit and connect the device a
s described in the module’s installation
instructions.
Step 4: Connect the battery
Note:
Connecting the battery does not start the system.
Fit a 7Ah lead-acid battery in the bottom-left corner of the control unit.
Connect the battery leads to the battery (red to positive and black to negative), and
connect the other end to the PCB (Figure 14). Also connect the transformer lead to the
PCB (Figure 14).
Step 5: Connect the mains cable
WARNING:
ENSURE THAT THE MAINS SUPPLY IS DISCONNECTED AND ISOLATED.
Connect the mains cable to the terminal block (Figure 16) and fit a strain-relief tie. Do not
apply power until after the lid is re-fitted.
