VFD68 Variable Frequency Drives (230 or 460 VAC)
6
Observe the following location guidelines:
•
Ensure that the mounting surface can support the drive, mounting hardware, and any user-supplied panel
or enclosure.
•
Mount drives on flat, even surfaces.
•
Allow sufficient space for wires and connections.
•
Do not mount the modules on surfaces that are prone to vibration or in locations where radio frequency or
electromagnetic emissions may cause interference.
•
Do not install the modules in airtight enclosures.
•
Do not install heat-generating devices that may cause the temperature to exceed the ambient operating
limit in the same enclosure as the modules.
The VFD68 drive has been approved for use in an enclosure. Approval tests were conducted under the
conditions in Table 2.
When mounting the VFD68 drive in an enclosure, ensure that the specified space around the drive is
maintained, and that the ambient conditions are within the specified limits.
IMPORTANT:
The VFD68 drive is intended to be mounted in an enclosure that only allows access
by trained and authorized personnel, and that prevents the ingress of contamination. It is designed for
use in an environment classified as pollution degree 2 in accordance with IEC 60664-1. This means that
only dry, non-conducting contamination is acceptable.

Surrounding air temperature is a temperature measured at a measurement position in an enclosure. Ambient air
temperature is a temperature outside an enclosure.

90% RH or less (noncondensing)
Storage Temperature
-40 to 65°C (-40 to 149°F)

Altitude limit given is for standard operation of the VFD. For operation at higher altitudes, derate by 3% for each 500 m
(1,640.4 ft), up to a maximum of 2,500 m (8,202 ft) (91% derating).
Vibration Limit: 5.9 m/s
