3.7. Guidelines for Mounting (IP66 Units)
Before mounting the drive, ensure that the chosen
location meets the environmental condition
requirements for the drive shown in section
11.1. Environmental on page 65
.
The drive must be mounted vertically, on a suitable
flat surface.
The minimum mounting clearances as shown in the
table below must be observed.
The mounting site and chosen mountings should be
sufficient to support the weight of the drives.
Using the drive as a template, or the dimensions
shown above, mark the locations required for drilling.
Suitable cable glands to maintain the ingress protection
of the drive are required. Gland holes for power and
motor cables are pre-moulded into the drive enclosure,
recommended gland sizes are shown below. Gland
holes for control cables may be cut as required.
The mounting location should be free from vibration.
Do not mount the drive in any area with excessive humidity, corrosive airborne chemicals or potentially dangerous dust particles.
Avoid mounting close to high heat sources.
The drive must not be mounted in direct sunlight. If necessary, install a suitable shade cover.
The mounting location must be free from frost.
Do not restrict the flow of air through the drive heatsink. The drive generates heat which must be naturally allowed to dissipate.
Correct air clearance around the drive must be observed.
If the location is subject to wide ambient temperature and air pressure variation, install a suitable pressure compensation valve in
the drive gland plate.
NOTE
If the drive has been in storage for a period longer than 2 years, the DC link capacitors must be reformed.

NOTE
Above are guidelines only and the operating ambient temperature of the drive MUST be
maintained within the limits shown in section
at all times.
3.8. Gland Plate
The use of a suitable gland system is required to maintain the appropriate IP / NEMA rating. The gland plate has pre moulded cable
entry holes for power and motor connections suitable for use with glands as shown in the following table. Where additional holes are
required, these can be drilled to suitable size. Please take care when drilling to avoid leaving any particles within the product.

UL rated ingress protection ("Type" ) is only met when cables are installed
using a UL recognized bushing or fitting for a flexible-conduit system
which meets the required level of protection ("Type").
For conduit installations the conduit entry holes require standard opening
to the required sizes specified per the NEC.
Not intended for installation using rigid conduit system.
