IMPORTANT: Reversing DC Bus Power polarity will permanently
damage your ClearPath motor.
Important Notes
x If using Teknic manufactured cables, you can safely skip this
test.
x Do not force or jam DMM probes into the connector.
Use smaller probe tips or find a safe alternative way to verify
that polarity is correct.
1. Start with the 5-position power connector disconnected from your
ClearPath-EC motor and the AC unplugged.
2. Power up your DC Bus Motor Power Supply.
3. Measure DC Bus Motor Power Supply voltage and
polarity. With a multimeter, measure the DC voltage from Bus
Motor Power+ (positive) to Bus Motor Power- (negative).
4. Power-up your logic power supply, if applicable.
5. Measure Logic Supply voltage and polarity. With a DMM,
carefully measure the Logic Supply voltage between Logic Power+
and Logic Power.
