Preventive measures
... against electric shock When carrying out repairs:
• Disconnect appliance from power
supply.
When running tests with power supply
on:
• Use a residual-current-operated cir-
cuit-breaker.
• Select protective conductor connec-
tion less than standard value.
... to prevent cut injuries • wear protective gloves.
