Operation description Required tool Approximate timing
Primary circuits contact resistance check
ISM shall be closed before the test,
there should not be any external circuits
connected to ISM main terminals that
provide parallel circuit with the ISM
main circuits otherwise tests will be
invalid. Visual check, no tool is required 1 minute
Test equipment shall be connected to
ISM main circuits terminals according to
Figure 81 in order exclude any
additional contact resistance and to
decrease measurement error. Main
contact resistance shall be measured by
appropriate equipment at test current
not less than 50 A. Resistance mesurement test equipment
with test current not less than 50 A
10 minutes
Measured values must not exceed limits
specified in Table 1. Visual check, no tool is required -
