Pre-Operation Checklist

3-32 Installation
Check of electrical items.
CAUTION: After completing the installation but before you apply power, be
sure to check the following items.
1. Measure the AC line voltage and verify it matches the control rating.
2. Inspect all power connections for accuracy, workmanship and tightness and
compliance to codes.
3. Verify control and motor are grounded to each other and the control is
connected to earth ground.
4. Check all signal wiring for accuracy.
5. Be certain all brake coils, contactors and relay coils have noise suppression.
This should be an R-C filter for AC coils and reverse biased diodes for DC coils.
MOV type transient suppression is not adequate.
WARNING: Make sure that unexpected operation of the motor shaft during start
up will not cause injury to personnel or damage to equipment.
Check of Motors and Couplings
1. Verify freedom of motion for all motor shafts.
2. Verify that all motor couplings are tight without backlash.
3. Verify the holding brakes if any, are properly adjusted to fully release.
