Danfoss VLT AHF 005 Design Guide

Motors with class e protection
When combined with an ATEX approved PTC monitoring
device like the VLT
®
PTC Thermistor Card MCB 112, instal-
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 classication. To attenuate the high
peak voltage, use a sine-wave lter 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 lters when shielded motor
cables are not used.

atmospheres.
9.4 Mounting Congurations
Table 9.1 lists the available mounting congurations for
each enclosure. For specic panel/wall mounting or
pedestal mounting installation instructions, see the
operating guide. See also chapter 8 Exterior and Terminal
Dimensions.
NOTICE
Improper mounting can result in overheating and
reduced performance.

Table 9.1 Mounting Congurations
Mounting considerations:
1)
•
Locate the unit as near to the motor as possible.
See chapter 7.6 Cable Specications 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.
