4.8 E3h/E4h Mechanical Installation

The E3h and E4h enclosure sizes are intended to be
mounted on a wall or on a mounting panel within an
enclosure. A plastic gland plate is installed on the
enclosure. It is designed to prevent unintentional access to
the terminals in an IP20/protected chasis unit.
NOTICE
Regeneration/Load share Option
Due to the exposed terminals at the top of the
enclosure, units with the regeneration/load share option
have an IP00 protection rating.
4.8.1 Attaching the E3h/E4h to a Mounting
Plate or Wall
1. Drill the mounting holes according to the
enclosure size. Refer to chapter 9.8 Enclosure
Dimensions.
2. Secure the top of the drive enclosure to the
mounting plate or wall.
3. Secure the base of the drive enclosure to the
mounting plate or wall.
4.8.2 Creating Cable Openings
The gland plate covers the bottom part of the drive
enclosure and must be installed to maintain the IP20/
Chassis protection rating. The gland plate consists of
plastic squares that can be cut out to provide cable access
to the terminals. See Illustration 4.7.
1. Remove the bottom panel and terminal cover.
See Illustration 4.8.
1a Detach the bottom panel by removing 4
T25 screws.
1b Remove 5 T20 screws that secure the
bottom of the drive to the top of the
terminal cover, and then pull the
terminal cover straight out.
2. Determine the size and position of the motor,
mains, and ground cables. Note their position and
measurements.
