Mounting Configurations - Danfoss VLT HVAC Drive FC 102 Design Manual

Mechanical Installation Con...
Motors with class e protection
When combined with an ATEX approved PTC monitoring
device like the VLT
lation does not need an individual approval from an
approbated organization.
Motors with class d/e protection
The motor itself has an e ignition protection class, while
the motor cabling and connection environment is in
compliance with the d classification. To attenuate the high
peak voltage, use a sine-wave filter at the drive output.
When using a drive in a potentially explosive
atmosphere, use the following:
•
Motors with ignition protection class d or e.
•
PTC temperature sensor to monitor the motor
temperature.
•
Short motor cables.
•
Sine-wave output filters when shielded motor
cables are not used.

Drives with the VLT

option are PTB-certified for potentially explosive
atmospheres.

9.4 Mounting Configurations

Table 9.1 lists the available mounting configurations for
each enclosure. For specific panel/wall mounting or

Mounting considerations:
•
Locate the unit as near to the motor as possible.
See chapter 7.6 Cable Specifications for the
maximum motor cable length.
•
Ensure unit stability by mounting the unit to a
solid surface.
•
Ensure that the strength of the mounting location
supports the unit weight.
•
Ensure that there is enough space around the
unit for proper cooling. Refer to
chapter 9.5 Cooling.
•
Ensure enough access to open the door.
•
Ensure cable entry from the bottom.
