figure 3-12 Mains connector
 Note: For the AC power supply connection, a minimum cross section of 1.5 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 unit.
 Note: Do not connect or disconnect the power cord at the mains connector while
power is on. Turn off mains power * before connecting the power cord at
the unit, then, engage mains again.
* Mains power must be interruptible 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 13 to 16 Amps for
240-Volt service. Always make sure that your local requirements are kept.
