TR200 Option Panel Operating Instructions
Solution
Correct voltage mismatch.
This could potentially dam-
age panel caution on apply-
ing power recommended.
Correct any wrong connec-
tions. This could potentially
case damage to panel.
Eliminate any ground faults
detected.
Eliminate any shorts detec-
ted.
Perform startup and verify
motor current is within spec-
ifications. If motor current is
exceeding nameplate FLA re-
duce the load on the motor.
Perform startup and verify
drive current is within speci-
fications. If not reduce the
load on the motor.
Tighten loose connections.
