Attaching the Mounting Bracket

Safety

Danger of residual voltage from capacitors.
An electric shock can be fatal.
▶
Danger due to insufficient ground conductor connection.
This can result in severe personal injury and damage to property.
▶
Danger due to soiling or water on the terminals and contacts in the connection
area.
The inverter may be damaged.

NOTE!
Protection class NEMA4X is only ensured when the inverter is mounted and
firmly screwed into the wall bracket.
The mounting bracket without inverter has no NEMA protection.
Selecting Dowels Important! Depending on the surface, different mounting materials may be re-
and Screws quired for installing the mounting bracket. These mounting materials are not part
of the scope of delivery for the inverter. The installer is responsible for selecting
the proper mounting materials.
Screw recom- For the installation of the inverter we recommend steel or aluminum screws with
mendation a diameter of 0.2–0.3 in. (6–8 mm).
WARNING!
Wait until the capacitors have discharged. Discharge takes 3 minutes.
WARNING!
The housing screws provide an adequate ground conductor connection for
grounding the housing and should not be replaced under any circumstances
by other screws that do not provide a reliable ground conductor connection.
CAUTION!
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
inserted inverter.
Protect the mounting bracket from soiling and moisture during installation.
