1.3.1 Electric shock hazards
Electric current
DANGER!
Danger of death due to electric current!
Danger of electric shock! Do not touch any live com-
ponents! Damaged insulation or damaged parts are
a life threatening hazard.
–
Have work on the electrical system carried out
only by skilled qualified electricians.
–
If the insulation is damaged, disconnect the
power supply immediately and have the insula-
tion repaired.
–
Before you start working on electric systems and
equipment, switch off the supply voltage and
secure it against being switched on accidentally.
Comply with the following safety rules:
–
Switch off the power supply.
–
Secure it against being switched on acciden-
tally.
–
Ensure that no voltage is present.
–
Connect to the earth; short circuit connection.
–
Do not bypass or disable any circuit breakers. Be
sure to maintain the correct current rating when
you replace a circuit breaker.
