4.7 E1h/E2h Mechanical Installation

The E1h and E2h enclosure size is intended only for floor
installation, and is shipped with a pedestal and a gland
plate. The pedestal and gland plate must be installed for
proper installation.
The pedestal is 200 mm (7.9 in) and has an opening in the
front to allow airflow necessary to cool the power
components of the drive.
The gland plate is necessary to provide cooling air to the
control components of the drive via the door fan, and to
maintain the IP21/Type 1 or IP54/Type 12 protection rating.
4.7.1 Securing the Pedestal to the Floor
The pedestal must be secured to the floor using 6 bolts
before installing the enclosure.
1. Determine proper placement of the unit,
concerning operating conditions and cable
access.
2. Access the mounting holes by removing the front
panel of the pedestal.
3. Set the pedestal on the floor and secure using 6
bolts through the mounting holes. Refer to the
circled areas in Illustration 4.3.
