8. Electrical installation
The provision of power supply, (protective) ground wire connection and line protection must be
made in accordance with the local regulations (responsible power company) and the applicable
National standards. The required electrical information can be found on the product label at the
side of the MX130/MX230, the terminal plan (labelling) and chapter 7.2 Controller.
All electrical connections should be carried out by a qualified and
authorised electrician in accordance with the latest issue of the IET
regulations. The equipment must be earthed. It is strongly
recommended that a high sensitivity differential switch (30mA)
(residual current device RCD) is fitted on the incoming electrical
supply.
Do not remove covers without first ensuring that the electrical
supply is suitably
isolated and cannot be switched on.
Do not attempt to supply electricity to the equipment unless the
protective covers
are correctly fitted and held securely in place.
Cables connected to the controller volt free contacts may be
supplied from another source and may remain live after the unit is
isolated. These must be isolated elsewhere. The user or the
installer is responsible for the installation of the
correct earthing and protection according to valid national and local
standards. All
operations must be carried out by a qualified electrician.

equipment must be connected to a mains isolator switch with a contact gap of at
least 3m. It is recommended the switch should be installed within 2m of the equipment.
