Wiring

Each unit is supplied with a control box to which the power supply will be connected through an automatic switch or a fused main switch.

Wiring should be carried out in accordance with the corre- sponding wiring diagram of the unit, taking into account gen- eral characteristics and limits of use (see corresponding ta- ble).

Wiring should always be carried out in accordance with ap- plicable national regulations.

Loose cables can cause overheating of terminals or incorrect opera- tion of the unit. Fire hazards may also exist. Therefore, make sure all cables are connected firmly.

Do not connect power supply to the unit, nor turn it on, until all tubing and wiring is connected. Check correct power supply connection to the units in accordance with the wiring diagrams.
