(4)  Measurement of insulation resistance.

A 

WARNING 

ELECTRIC  SHOCK  can  kill

*  Measurement  should be made  after the machine  stops.

-   Using a 500V megger,  make  a check  once  a month to  ensure that the insulation 

resistance is more  than  1M  £3.

Measurement:

Disconnect the  load side  cable from  the  output terminal  as  shown at below.  Turn  ON 

the  circuit breaker and measure  the insulation resistance  between the output terminal 

bolt and the bonnet.

—  If the  measured resistance  is  less than  1M  Q ,  it may cause electric leakage or fire 

accident.  Wipe  off dirt and oil on the  output terminals,  circuit breakers  and generator 

leads  (cables)  and  dry them  thoroughly.

If the  insulation resistance is not recovered after cleaning,  contact distributor or our 

office.
