Danger to life as a result of hazardous voltages when connecting an unsuitable power
supply
Death or serious injury can result when live parts are touched in the event of a fault.
• For all connections and terminals of the electronic boards, only use power supplies that
In order to install the inverter in compliance with UL, you may only connect the DO 0 and
DO 2 relay outputs of the Control Unit using copper wires approved for 75 °C.
Danger to life as a result of a hazardous voltage at the Control Unit
If the insulation is damaged on the lines that are connected to the terminals DO 0 and DO
2, parts of the Control Unit may still be connected to the power supply. When connecting
higher voltages at terminals DO 0 and DO 2, there is a risk of electric shock when touching
the Control Unit.
• Only connect dangerous voltages using cables with double insulation at relay outputs
NOTICE
Damage to the inverter when using long signal cables
Using long cables at the inverter's digital inputs and 24 V power supply can lead to
overvoltage during switching operations. Overvoltages can damage the inverter.
• If you use cables of more than 30 m at the digital inputs and 24 V power supply, connect
