20 PACMotion VFD AC Variable Speed Drive User Guide GFK-3111A
Guidelines for Mounting (IP55 Units)
• Before mounting the drive, ensure that the chosen location meets the environmental condition
requirements for the drive shown in section Environmental on page 84.
• The drive must be mounted vertically, on a suitable at surface.
• The minimum mounting clearances as shown in the table below must be observed.
• The mounting site and chosen mountings should be sufcient to support the weight of the drives.
• IP55 units do not require mounting inside an electrical control cabinet; however they may be if desired.
• Using the drive as a template, or the dimensions shown above, mark the locations required for drilling.
• Suitable cable glands to maintain the IP protection of the drive are required. Gland sizes should be
selected based on the number and size of the required connection cables. Drives are supplied with a
plain, undrilled gland plate to allow the correct hole sizes to be cut as required. Remove the gland plate
from the drive prior to drilling.
