Safety and Precautions
Safety precautions and switch on
After installing the CCU and all cabling, ensure that the following points are checked before switching the
mains power on:
•The mains socket outlet shall be installed near the equipment and shall be easily accessible.
•There is a reliable earth at the mains supply socket earth pin.
•The cabled extensions have a telephone or Featurephone connected.
•The CCU PCB cover has been replaced, if it was previously removed.
•Switch on the mains power and allow at least eight seconds for the CCU to go through its power up
routine.
Electrostatic precaution (ESP)
The BT Inspiration contains electrostatic components. To ensure long term reliability of the system,
electrostatic precautions should be taken when handling any of the system module PCB’s.
A connector is provided on the MDF for connection of ESP straps.
If a functional earth is connected to the system it can be used for electrostatic precautions (ESP).
CAUTION
The mains protective earth should not be used for electrostatic precautions (ESP)

Installing the CCU
Location for Central Control Unit (CCU)
The CCU is intended for installation in a residential or office-type environment. It needs to be mounted at a
convenient working height on a dry flat wall. The normal height is 1 metre from the floor to the bottom of
the CCU case.
Allow at least 100 mm of free space all around the CCU for ventilation and 310 mm to the right or
underneath the CCU for the addition of the Battery Back Up unit.
The CCU needs to be within approximately two meters, of a dedicated mains power supply outlet. The CCU
must not share the same mains supply socket with any other electrical appliance.
Mounting the CCU
When a suitable location has been found, mark the screw locations on the mounting surface using the
mounting bracket provided.
If the CCU is being mounted on masonry or plasterboard, suitable wall plugs must be used. Drill and plug
four holes in the wall at the marked locations. The holes should be deep enough to accept a 2.5cm screw.
CCU Mounting bracket
The main unit is mounted on a wall using the bracket supplied and should have top and side clearance as
shown.
CAUTION
Do not site the CCU where it will be subjected to excessive levels of heat, dust damp or high humidity.
Locating the equipment near sources of electromagnetic radiation such as heavy electrical switch-gear, lift
machinery or electric arc welders should be specifically avoided.

Securing the CCU to the wall
Locate and mark the position of the Fixing screws at the top and bottom of the MDF area. Remove the unit.
Drill and plug the screw holes, deep enough to accept a 2.5cm (one inch) No. 8 round-head screw. Relocate
the unit on the bracket and screw home the fixing screws. Ensure that there is sufficient space around the
CCU to allow adequate ventilation.

Caution
At no time should any system module be removed or inserted when power is applied to the system.
Always isolate the mains supply when installing and/or upgrading system module hardware
Note: When fitting a Battery Backup Unit (BBU), there are two similar screw holes to those on the main
CCU, located on the left hand side of the BBU base. These screw holes are used to secure the BBU to the
wall when it has been positioned correctly on the wall-mounting bracket. Please refer to the Battery Backup
Unit section of this guide.
