1.4 Mounting instructions

1.4.1 Classification

The COMBIVERT F5 is classified as an "Open Type" inverter with an IP20 rating
and must be mounted inside of a control cabinet.

1.4.2 Physical Mounting

Install the inverter in a stationary location offering a firm mounting point with low
vibration.
Installation of the inverter on moving system may require special earth ground
connections to the inverter. Please consult KEBCO.
For best high frequency grounding, install the inverter on a bare metal sub-panel, i.e.
zinc plated steel or galvanized steel.
Take into consideration the minimum clearance distances when positioning the inverter
(see drawing below). The F5 series inverters are designed for vertical installation and
can be aligned next to each other. Maintain a distance of at least 2 inches in front of the
unit. Make sure cooling is sufficient.

1.4.3 Harsh Environments

For extended life, prevent dust from getting into the inverter. Select units with conformal
coating when the inside of the control cabinet may be occasionally subject dust,
moisture, or other substances which could build up over time.
When installing the unit inside a sealed enclosure, make sure the enclosure is sized
correctly for proper heat dissipation or that a cooling system has been installed in the
panel.
Protect the inverter against conductive and corrosive gases and
liquids. Water or mist should not be allowed into the inverter.
The COMBIVERT F5 inverter must be installed in an explosion-proof enclosure
when operating in an explosion-proof environment.
