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.
WARNING
Hazardous Voltage!
Failure to ensure that all enclosure doors are closed and
properly secured with fasteners when operating
equipment could result in death or serious injury.

2. Be sure the input disconnect is in the correct position,
either "on" or "off" depending on the work to be
performed.
3. Check the status of the drive shutdown interlocks, if
used. These interlocks can be limit switches, guards or
safety switches installed around the driven machine or
the system interface controller.
WARNING
Bypassed Electrical Interlocks!
Failure to return all interlocks to operation when the
startup is completed could result in death, serious
injury or equipment damage. The electrical interlocks
provide machine and personal protection. If deactivated
or bypassed for servicing, use extreme caution when
performing the startup.
4. Check to see that the AFDG/AFDU is properly ground to
earth. See
"Grounding the Cabinet," p. 20
Power and Control Wiring," p.
WARNING
Proper Field Wiring and Grounding
Required!
Failure to follow code could result in death or serious
injury. All field wiring MUST be performed by qualified
personnel. Improperly installed and grounded field
wiring poses FIRE and ELECTROCUTION hazards. To
avoid these hazards, you MUST follow requirements for
field wiring installation and grounding as described in
NEC and your local/state electrical codes.
