DANGER!
Life-threatening electrical hazard!
Contact with live components presents an immediate life-
threatening hazard from electrocution. Damaged insulation or
individual components can be life- threatening.
- During all work on the electrical connection and on electrical
cables, switch off the unit and ensure that no voltage is present.
- Allow only electrical technicians/electricians to work on
electrical equipment.
- Connect the unit only to a receptacle with a VDE protective
contact.
- In the event of damage to the power cable, immediately
disconnect power by pulling the power plug out of the
receptacle and initiate repairs.
- Use only tested, undamaged power cables.
- Always grasp the power plug when pulling, never the power
cable.
- Keep the cable length in mind; consider use of a strain relief.
- Keep moisture away from live components.
Exposure to moisture could result in short-circuits.
- Never operate the unit in a moist environment and/or place it in
water or other liquids.
- Never operate the unit outdoors or under similar conditions
without a 30-mA residual-current-operated device at the power
source.
- Never bypass fuses or disable them. When replacing fuses,
always use the correct amperage rating.
- Pull the power plug when performing all maintenance work.
- If the insulation is damaged, immediately disconnect the power
source and initiate repairs.
