For the AC power supply connection, a minimum cross section of 1.5 mm
2
is required and for the DC power supply connection, a minimum cross
section of 2.5 mm
2
is required. Each wire must observe the applicable
national regulations regarding loop impedance, voltage drop, and
methods of installation. Make sure to connect the correct voltage to the

Note: Do not connect or disconnect the power cord at the mains connector
while power is on. Turn off mains* power before connecting the

Mains power must be interrupted with an external mains breaker. For the mains breaker, observe
the following recommendation:
120 Volt / 20 Amp max. or 240 Volt / 16 Amp, single-phase, 50 / 60 Hz AC service is needed, i.e.
the external AC breaker should be 20 Amps max. for 120-Volt service or 16 Amps for 240-Volt
service.
For the DC power supply, observe the local regulations of the DC service provider.
