8 ATTACHMENT
The recommended tightening torques for the medium voltage
(MV) and low voltage (LV) connections, are as follows.
(*) The medium voltage terminals include three nuts, but only the two upper ones should be handled, of fixed ones on the terminal, since the
task of the lower one is to apply pressure to the insulator joint and if loosened, it could cause loss of dielectric fluid.
