Grounding of mounting structures

Make sure all cross-members or shelves on which drive system components are
mounted are properly grounded and the connecting surfaces left unpainted.
Notes:
Ensure that the components are properly grounded through their fastening points to
the installation base. It is recommended that the mains filter (if present) and the drive
be mounted on the same mounting plate.


Cabinet heaters

Use a cabinet heater if there is a risk of condensation in the cabinet. Although the
primary function of the heater is to keep the air dry, it may also be required for heating
at low temperatures. When placing the heater, follow the instructions provided by its
manufacturer.

Installation procedure



Requirements for the installation site

The drive must be installed in an upright position with the mounting plate against a
wall. MicroFlex e190 drives can be installed tightly side by side. Make sure that the
installation site complies with these requirements:
• The installation site has sufficient ventilation to prevent overheating of the drive.
• The operation conditions of the drive agree with the specifications in
conditions (page 157).
• The wall is vertical, not flammable and strong enough to hold the weight of the
drive. See Dimensions and weights
• The material below the installation is not flammable.
• There is enough free space above and below the drive for cooling air flow, service
and maintenance. There is enough free space in front of the drive for operation,
service and maintenance.


Required tools

• Slot screwdrivers for the screw type connectors.
• A drill and screws or bolts for mounting the MicroFlex e190.
• Wire stripper.
• For UL installations, use UL listed closed loop connectors that are of appropriate
size for the wire gauge being used.
Connectors are to be installed using only the crimp tool specified by the manufacturer
of the connector.
