Preparation
Remove the front door plate containing the circuit board by unscrewing the door hinge. This has a connection to the base PCB,
which needs to be removed. Exercise static precautions to prevent damage to the electronics. Store the front panel assembly
safely until the master handset is mounted and cables have been attached.
Before mounting the unit on the wall it is advisable to remove the cable knockouts. Decide how the wiring will be brought into the
panel and remove the required knockouts for cable entry. If a knockout is removed, fill the hole with a good quality cable gland.
On the bottom face a single knockout is for the incoming mains. Mains SHOULD NOT enter the box by any other hole. If additional
holes are required, then the can be drilled as shown below, taking care not to obscure the battery or PCB locations.
Unused knockouts must be left unopened to comply with the LVD. Accidentally knocked out holes should be blanked off. This work
must be carried out prior to the re-installation of circuit boards.
