NOTE
Internally bypassed models IS4x0350B to IS4x1000B have input and output busbars at both the top and bottom of the
unit. The IS3x0255B is different, with input only busbars at the top of the unit. It can be mounted 'Top in, Bottom out' or
'Bottom in, Bottom out'. These busbars do not need to be adjusted.
4.1.2 Ground terminals
Ground terminals are located at the back of the soft starter.
 IS1x0023B to IS1x0105B have one terminal on the input side (top).
 IS2x0145B to IS4x1000B and IS3x0255N to IS561600N have two terminals, one on the input side (top) and one on the
output side (bottom).
The ground terminal may also be used for a ground shield connection if necessary.
