12General1.4 Mounting instructions1.4.1 ClassificationThe elevator drive is classified as an "Open Type" inverter with an IP20rating and is intended for "use in a pollution degree 2 environment."The unit must be mounted inside of a control cabinet offering properenvironmental protection.1.4.2 Physical MountingInstall the inverter in a stationary location offering a fi rm mounting pointwith low vibration.Installation of the inverter on a moving system may require specialearth ground connections to the inverter.For best high frequency grounding, install the inverter on a bare metalsub-panel, i.e. zinc plated steel or galvanized steel.Take into consideration the minimum clearance distances whenpositioning the inverter (see drawing below). The F5 series invertersare designed for vertical installation and can be aligned next to eachother. Maintain a distance of at least 2 inches in front of the unit. Makesure cooling is sufficient. 1.4.3 Harsh EnvironmentsFor extended life, prevent dust from getting into the inverter.When installing the unit inside a sealed enclosure, make sure theenclosure is sized correctly for proper heat dissipation or that a coolingsystem has been installed in the panel.Protect the inverter against conductive and corrosive gases andliquids. Water or mist should not be allowed into the inverter.The F5 elevator drive inverter must be installed in an explosion-proofenclosure when operating in an explosion-proof environment.
