Information about the power supply
Injury to persons or damage to property when operated on an incorrect power supply
system
If you connect the device to an unsuitable power supply, the device receives voltages and
currents that are too high or too low.
Injuries to persons, malfunctions or a damage to the device can result.
• The permissible rated voltage of the device must match the local supply voltage.
• Operate the device only in grounded power supply networks (TN networks in accordance
with VDE 0100, Part 100 or IEC 60364-1).
• Operation in non-grounded or impedance-grounded networks is not permitted.
Risk of electric shock
The on/off button and on/off switch do not fully disconnect the device from the line voltage.
There is also a risk of fire if the device or connecting lines are damaged.
• Always fully disconnect the device from the mains voltage before performing work on
the device or when the device will not be used over an extended period of time.
• For control cabinet installation: Use a central, easily accessible AC circuit breaker close to
the device, if possible.
