WARNING
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.
WARNING
Safety regulations- connecting cable
Use only AC or DC connecting cables which comply with the local safety regulations.
Otherwise, there is a risk of fire and electric shock. This can result in personal injury or
property damage.
• Ensure that the AC or DC connecting cables comply with the safety regulations of the
country in which the device is installed and bear the marks required in each case.
•
Connect the protective conductor in accordance with the operating instructions.
WARNING
Risk of electric shock
The on/off button and on/off switch do not fully disconnect the device from the mains.
There is also a risk of fire if the device or connecting lines are damaged.
•
Always fully disconnect the device from the line voltage before performing work on the
device or when the device will not be used over an extended period of time.
• For control cabinet mounting: Use a central AC circuit breaker as near as possible to the
device and connect the device to a protective conductor.
•
When you install the device, make sure that the power supply connector is easily
accessible.
Note
The varying voltage power supply module is designed for operation on 120/230/240 V AC
networks. The setting of the voltage range takes place automatically.
