DANGER
Risk of fatal injury from electrical current!
In case of contact with live parts, there is immediate danger to life by
electrocution.
Damage to the insulation or individual components can be dangerous
to life.
• Work on the electrical system may only be performed by trained
electricians.
• In case of damage to the insulation, switch off voltage supply
immediately and promptly initiate repairs.
• Before starting work on live parts of electrical systems and operating
materials, it must be ensured that the equipment is de-energised for
the duration of the work. Observe the 5 safety rules:
– Disconnect.
– Secure against reconnection.
– Ensure that there is no voltage.
– Earth and short circuit.
– Neighbouring parts that are live must be covered up or fenced off.
• Never bypass or disable fuses. The correct amperage must be used
when replacing fuses.
• Keep moisture away from live parts. It may cause short circuits.
