7 Operation26 100_0402_op_0003.fm7.5 GroundFor generator sets that are to supply a facility in a TT network, or if residualcurrent protection is required in the TT network, or if this equipment must be usedfor additional protection due to conditions or regulations, only 30 mA residualcurrent protective switches may be used as protective devices. The 30 mAresidual current protective switch must be installed ON the generator set itself,but at least on the nearest possible position in relation to the generator set. Onlywith this type of installation is it allowed and necessary to establish the groundconnection of the generator framework via the point provided on the frame (seeground symbol 5019).7.6 Heavy duty operationDo not operate this generator for longer than 20-30 minutes under maximumelectrical load rating. For continuous operation, do not exceed the continuous(prime) power output of the generator. See technical data of the generator in thisoperator's manual.CAUTIONThe mid-point (neutral) conductor of this equipment is not grounded. Do notdrive the PE rod into the ground under normal operating conditions.Refer to the local regulations if the equipment is intended to power abuilding or similar system.wc_gr001286
