Connecting to AC mains

Electrical specications

AC mains specications

Verify the electrical conformity and compatibility of the mains supply.

Only connect the product to an AC power outlet rated 100-240 V, 50-60 Hz, with the following current values:
100-120 V: 20 A
200-240 V: 10 A
WARNING: The product is of Class 1 construction and shall be connected to a mains socket outlet with a

protective connection to earth.

Three-phase circuit

When the product is used in a three-phase circuit, verify the electrical conformity and

compatibility of the three-phase circuit.

Verify that the three phases work, and balance the loads between the three phases.
Verify that the neutral and earth work.
Never try to emulate a 230 V circuit connecting an apparatus to two live wires of a 120 V three-phase circuit.
