■ A main switch or other means of disconnection, having a contact separation in all poles, must be incorporated in the fi xed wiring in
accordance with relevant local laws and regulations.
■ Switch off the power supply before making any connections.
■ Never squeeze bundled cables and make sure they do not come in contact with the piping and sharp edges. Make sure no
