Installation and Maintenance Manual

Safety Precautions during installation and system upgrades

Always unplug or isolate the mains supply when installing or upgrading the system.

After installing the central control unit (CCU) and all required modules, ensure that the following points are checked before switching the mains power on:

•The cabled extensions have a DTMF telephone or a (V8/V16) Featurephone connected.

•The CCU cover is in place and locked.

After switching on the Mains allow approximately 30 seconds for the CCU to go through its power up routine.

Electrostatic precaution (ESP)

The BT Versatility contains electrostatic components. To ensure long-term reliability of the system, electrostatic precautions should be taken when handling any of the system PCBs that are not enclosed in plastic. An ESP pillar is located on the CCU MDF.

Lightning and surge voltage protection

Extension cabling should not be exposed to high voltage surges, (for example, surges induced by lightning or neighbouring high current-carrying cables). If this is a possibility, external protection of the Main Equipment and Extensions using ‘earthed line surge protectors’ is essential.
