4.7.3 Creating Cable Openings
The gland plate is a sheet of metal with studs along the
outer edge. The gland plate provides cable entry and cable
termination points, and must be installed to maintain the
IP21/IP54 (Type 1/Type 12) protection rating. The plate is
placed between the drive enclosure and the pedestal.
Depending on stud orientation, the plate can be installed
from inside the enclosure or the pedestal. For gland plate
dimensions, see
chapter 9.8.1 E1h Exterior Dimensions
Refer to
for the following steps.
1.
Create cable entry holes in the gland plate using
a sheet metal punch.
2.
Insert the gland plate using 1 of the following
methods:
2a
To insert the gland plate through the
pedestal, slide the gland plate through
the slot (4) in the front of the pedestal.
2b
To insert the gland plate through the
enclosure, angle the gland plate until it
can be slid under the slotted brackets.
3.
Align the studs on the gland plate to the holes in
the pedestal and secure with 10 M5 nuts (2).
4.
Torque each nut to 2.3 Nm (20 in-lb).

Illustration 4.6 Installing the Gland Plate
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
.
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
.
1.
Remove the bottom panel and terminal cover.
See
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.
3.
Based on the measurement and positions of the
cables, create openings in the plastic gland plate
by cutting out the necessary squares.
4.
Slide the plastic gland plate (7) onto the bottom
rails of the terminal cover.
5.
Tilt the front of the terminal cover downward
until the fastener points (8) rest on the slotted
drive brackets (6).
