installation
When unpacking the inverter, carefully inspect the product and make sure it has not been damaged during
transportation. An inverter with cracks, dents or other visual damage shall not be installed.
The inverter must not be installed so that outlet air from another inverter or other equipment blows directly
into the inverter air intake. A minimum of 80 mm clearance must be kept above and below the inverter.
All terminals are accessed by opening the plastic cover. To be able to use the snap-and-hold-open
functionality of the cover, a free space of 200 mm is required above the inverter.
During installation it is important that no foreign objects, such as cable strands or screws, fall into the
inverter as a short circuit may occur. Drilling in chassis or cover is not allowed.
After installation, make sure all grommets at the cable entries are mounted and that the cover is closed and
secured with its screws to avoid access to dangerous voltages.
1.1 Mounting
Unscrew the two lower captive screws and loosen the inverter from the backplate.
Fasten backplate to a vertical surface using four screws. Make sure that the top mounting screws are
sufficiently strong to hold the entire weight of the inverter.
Place the inverter on the backplate by mating the chassis cut-out to the backplate hooks. Tighten the lower
captive screws on both sides.
