DANGER
Risk of death from electrocution!
❒
Only allow licensed electricians to carry out electrical work to the electrical
system.
❒ If the isolation gets damaged, switch off the power supply immediately and
have it repaired.
❒ Prior to commencing work to active parts, shut off electrical systems and
equipment so that they are no longer live and secure so that they remain off
for the duration of the work. Follow the five safety rules:
- Disconnect.
- Secure against switching back on.
- Check the system is no longer live.
- Earth and short circuit.
- Cover or shield any adjacent live parts.
❒ Never bypass or disable fuses. When replacing fuses, use the correct
amperage.
❒ Always lay lines and cables far away from hot surfaces.
❒ Use shielded cables when using frequency converters.
❒ Ensure that the system is properly earthed with a protective earth system.
Have all component assemblies checked at regular intervals to ensure the
correct earthing.
❒ Keep moisture away from live parts. This can cause short circuits.
➥ Touching live parts can cause immediate death by electrocution. Damage
to the isolation or individual components can be perilous.
