Installation
Pre-Operation Checks
Check of Electrical Items
After completing all the installation steps and before applying line
power to the system, carefully check the following items:
1. Verify AC line voltage at source matches control rating.
2. Inspect all power terminations for workmanship and
tightness.
3. Verify control and motor are grounded to each other and the
control is connected to earth ground.
4. Check incoming signal wiring for accuracy.
Be certain all brake coils, contactors, and relay coils have
noise suppression. This should be an R-C filter for AC coils
and reverse polarity diodes for DC coils. MOV type
transient suppression is not adequate.
