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 remote 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
16 Amps for 240-Volt service.
