II Connecting the Power Cable
1 Examine the voltage selector switch on the back of the device in order to assure that the selected voltage
coincides with available mains power. If this is not the case, observe the note printed on the device’s mains
inlet plug, and make sure that the correct fuse is utilized.
2 The on/off switch in the device’s front panel must be switched off before the power supply is connected to
the mains.
3 Connect the 3-wire conductor cable with plug to the mains outlet. The device must be connected via the
mains cable to the protective earth conductor.
4 Press the switch on the front panel in order to turn the device on. The device is now ready for operation.
III Fuse
1 The fuse is located in proximity to the mains power inlet plug on the back of the device. Observe the
following points if input voltage is changed and/or the fuse is replaced:
2 The on/off switch must be turned off and the power supply must be disconnected from all other devices
before changing input voltage and/or replacing the fuse.
3 Press the fuse holder with a screwdriver and the fuse pops out.
4 Pull the fuse out and replace it with a new fuse which complies with the specifications on the label next to
the mains power inlet plug.
Warning: Use approved fuse types only in order to prevent damage to the device.
5 If input voltage needs to be changed, replace the fuse as described above and then set the voltage selector
switch to the desired position (230 V AC or 110 V AC). The selected input voltage appears at the selector
switch.
IV Power Supply Output Terminals
1 For reasons of safety, make sure that there are no short-circuits between the positive and negative
terminals. The device is equipped with short-circuit protection, but a short-circuit may result in injury to the
user.
2 The output cable must be insulated all the way up to the connected power consumer.
3 The power supply should be switched on 30 minutes before the power consumer is used.
