Inverter Mounting	and Installation

This section will guide you through the following basic steps of installation:

1.Study the warnings associated with mounting the inverter.

2.Select a suitable mounting location.

3.Place covers over the inverter’s ventilation openings to prevent debris from entering.

4.Check the inverter mounting dimensions for footprint and mounting hole locations.

5.Study the caution and warning messages associated with wiring the inverter.

6.Connect wiring for the inverter power input.

7.Connect wiring to the motor.

8.Remove any covers applied in Step 3 from the inverter’s ventilation openings.

9.Perform a powerup test.

10.Make observations and check your installation.

Choosing a Mounting Location

Step 1: Study the following caution messages associated with mounting the inverter.

1 This is the time when mistakes are most likely to occur that will result in expensive rework, equipment damage, or personal injury.

CAUTION: Be sure to install the unit on flame-resistant material such as a steel plate. Otherwise, there is the danger of fire.

CAUTION: Be sure not to place any flammable materials near the inverter. Otherwise, there is the danger of fire.

CAUTION: Be sure not to let the foreign matter enter vent openings in the inverter housing, such as wire clippings, spatter from welding, metal shavings, dust, etc. Other- wise, there is the danger of fire.

CAUTION: Be sure to install the inverter in a place which can bear the weight accord- ing to the specifications in the text (Chapter 1, Specifications Tables). Otherwise, it may fall and cause injury to personnel.

CAUTION: Be sure to install the unit on a perpendicular wall which is not subject to vibration. Otherwise, it may fall and cause injury to personnel.

CAUTION: Be sure not to install or operate an inverter which is damaged or has missing parts. Otherwise, it may cause injury to personnel.

CAUTION: Be sure to install the inverter in a well-ventilated room which does not have direct exposure to sunlight, a tendency for high temperature, high humidity or dew condensation, high levels of dust, corrosive gas, explosive gas, inflammable gas, grinding-fluid mist, salt damage, etc. Otherwise, there is the danger of fire.
