Attaching the Mounting Bracket

Safety

Selecting dowels
IMPORTANT! Depending on the surface, different mounting materials may be required for
and screws
installing the mounting bracket. These mounting materials are not part of the scope of de-
livery for the inverter. The installer is responsible for selecting the proper mounting mate-
rials.
Screw recom-
For the installation of the inverter we recommend steel or aluminum screws with a diameter
mendation
of 0.2–0.3 in. (6–8 mm).

WARNING! An electric shock can be fatal. Danger of residual voltage from ca-
pacitors. Wait until the capacitors have discharged. Discharge takes 5 minutes.
CAUTION! The inverter can be damaged by soiling or water on the terminals and
contacts of the connection area.
-
When drilling, make sure that terminals and contacts in the connection area
do not become soiled or wet.
-
The mounting bracket without integrated inverter does not correspond to the
degree of protection according to the data sheet. For this reason do not leave
the mounting bracket exposed to environmental influences without the insert-
ed inverter.
-
Protect the mounting bracket from soiling and moisture during installation.
NOTE! Protection class NEMA4X is only ensured when the inverter is mounted
and firmly screwed into the mounting bracket.
The mounting bracket without inverter has no NEMA protection.
WARNING! An inadequate ground conductor connection can cause serious inju-
ry and damage to property. The housing screws provide an adequate ground con-
ductor connection for grounding the housing and should not be replaced under
any circumstances by other screws that do not provide a reliable ground conduc-
tor connection.
