9.11 IEC-fans: Replacing fan motor
WARNING:
Each fan is equipped with a fan guard and a lockable service switch. The wire
spacing in the fan guard and the safety distance of the blade correspond to the
European safety standard. The safety guards are protections from contact only.
Do not remove the safety guard before the fan is shut down. The rotating impeller
may catch in your clothes, cut you or pull you in.
WARNING:
Before starting the service operation, ensure that the electrical supply is reliably
isolated; use the lockout/tag-out system. Always check with a voltmeter that the unit
is electrically isolated and shut off.
WARNING:
Only an authorized electrician may perform the electric connections.
WARNING:
Sharp edges. Use protection glasses, safety gloves, shoes and clothes.
