Set the current at 80% or less of the
rating of the Shunt when energizing it.
Tighten the connecting bolt(s) of
electric cables to reduce contact
resistance.
For models with a rating of 250A or
more, the nuts and bolts for current
terminals shown below will be
provided with the device. For models
with a rating of 200A or less, refer to
the outer dimensional drawings on
the following page.
