1.3 Mounting instructions

1.3.1 Classification

The elevator drive is classified as an "Open Type" inverter with an
IP20 rating and is intended for use in a "pollution degree 2 environ-
ment." The unit must be mounted inside of a control cabinet offering
proper environmental protection.

1.3.2 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.
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 position-
ing 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.

1.3.3 Harsh Environments

For extended life, prevent dust from getting into the inverter.
When installing the unit inside a sealed enclosure, make sure the enclo-
sure 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.
