Note:
Graphic labels (shown above) are used for CE
application only.
Important:
•
Before servicing, disconnect all power sources and
allow at least 10 minutes for capacitors to discharge.
•
All electrical enclosures—unit or remote—are IP2X.
Motor Checks
1. Check the motor for proper horsepower and voltage
ratings. Verify that the motor full load amps do not
exceed the nameplate rating of the controller.
2. Check that the motor terminals are correctly connected
to the controller’s power terminals for the proper
voltage and motor rotation.
3. Use an ohmmeter to check for any short circuits
between the motor frame and the motor power leads.
If a short circuit exists, it must be corrected before
proceeding.
Controller Checks
4. Check that local, state and national electric codes have
been observed for the installation and wiring of this
equipment.
5. Check that all external power wiring has been properly
routed through the cabinet.
6. Check all input power and output power connections
for tightness.
7. Check the chassis ground and other connections for
tightness.
8. Check all external control connections (this includes
the operator station connections) for tightness.
9. Check to assure incoming power to the drive is phased
A, B, C.

WARNING
Capacitors Must Be Allowed To
Discharge!
Failure to disconnect power and discharge capacitors
before servicing could result in death or serious injury.
Each time power is removed, allow at least 10 minutes
for DC units to discharge after power is disconnected
before servicing. Use extreme caution when applying
power. Equipment terminals and other internal parts of
the controller are at line voltage when AC power is
connected to the controller. All ungrounded conductors
of the AC power line must be disconnected from the
controller before it is safe to touch any internal parts of
this equipment.
NOTICE
Disconnect Motor Leads!
Failure to disconnect all motor leads prior to megging
the motor could cause equipment damage.

NOTICE
Perform Visual Inspection!
Before powering up this drive for the first time conduct
a visual inspection for the following:
•
Shipping damage.
•
Signs of moisture.
•
Signs of debris or dust from storage.
•
Signs of corrosion on components and/or enclosure.
These conditions could cause equipment damage. Do
not power up equipment if you have concerns
regarding equipment condition. Upon initial power up,
remain in the area for the first two hours of operation
and observe the chiller and drive for any abnormalities.
Contact CenTraVac™ Technical Support for assistance if
needed.
