installation
When unpacking the inverter, carefully inspect the product and make sure it has not been damaged during
transportation. Inverter with cracks, dents or other visual damage shall not be installed.
The inverter must not be installed such 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, and a
minimum of 20 mm vertical gap must be kept between inverters, to ensure sufficient air flow.
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 the cover is closed and
secured with its screws to avoid contact with dangerous voltages.
3.1 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.
The cover is opened by unscrewing the two captive screws in the plastic cover and fold up the cover until it snaps
tight. There are two possible positions for the cover. Close the cover by pulling it out and fold down. Be careful not
to break the snaps in the cover when folding down. Tighten the screws in the plastic cover.
The plastic cover can be removed by unscrewing the two upper screws after the cover is opened. The cable from
the cover to the control board must be carefully removed from the control board. Replace in reverse order.
