Insert the power cable plug into a power outlet with a
protective ground contact. Do not use an extension cord
without a protective conductor.
Before turning on the unit, connect all grounding terminals and
extension cords to a protective ground via a ground socket. Any
interruption of the protective grounding is a potential shock
hazard and may cause personal injury. Whenever the ground
protection is impaired, do not use the unit and secure it against
any accidental operation.
Do not tamper with the protective ground terminal.
