• The grounding connector shall be sized in accordance with the NEC or Ca-
nadian Electrical Code. The connection shall be made by a UL listed or CSA
certified closed-loop terminal connector sized for the wire gauge involved.
The connector is to be fixed using the crimp tool specified by the connector
manufacturer.
• Do not perform a megger test between the Drive terminals or on the control
circuit terminals.
• Because the ambient temperature greatly affects Drive life and reliability, do
not install the Drive in any location that exceeds the allowable temperature.
Leave the ventilation cover attached for temperatures of 104° F (40° C) or
below.
• Be sure to remove the desicant dryer packet(s) when unpacking the Drive.
(If not removed these packets may become lodged in the fan or air passages
and cause the Drive to overheat).
• The Drive must be mounted on a wall that is constructed of heat resistant
material. While the Drive is operating, the temperature of the Drive's cooling
fins can rise to a temperature of 194° F (90°C).
• Do not touch or damage any components when handling the device. Chang-
ing of isolation gaps or removing the isolation covers is not permissible.
• Protect the device from disallowed environmental conditions (temperature,
humidity, shock etc.)
• The electrical commissioning should only be carried out by qualified person-
nel, who are also responsible for the provision of a suitable ground connec-
tion and a protected power supply feeder in accordance with the local and
national regulations. The motor must be protected against overloads.
• No dielectric tests should be carried out on parts of the frequency inverter. A
suitable measuring instrument (internal resistance of at least 10 kΩ/V) should
be used for measuring the signal voltages.
• No voltage should be connected to the output of the drive (terminals C, D).
Note!
The terms "Converters", "Controller" and "Drive" are sometimes used interchangably throughout the
industry. We will use the term "Drive" in this document
