Connection to these instruments is made via a stud and bolt and great care must
be taken when connecting heavy duty ring terminals to the appropriately sized
stud or alternatively, to an “L” bracket on the HF500 shunt.
It is essential that 2 correctly sized spanners are used at all times (see table
below) so that adequate torque can be applied to the bolt without transferring
excessive turning force to the stud
Any damage caused to the fixing stud will be irreparable
