Fitting the inverter mounting bracket
Safety
WARNING!
Danger due to residual voltage in capacitors.
This may result in an electric shock.
▶
Wait for the capacitors to discharge. The discharge time is five minutes.
CAUTION!
Danger due to dirt or water on the terminals and contacts of the inverter's connec-
tion area.
This may result in damage to the inverter.
▶
When drilling, ensure that terminals and contacts in the connection area do not
become dirty or wet.
▶
The mounting bracket without a power stage set does not conform to the protection
class of the inverter as a whole, and therefore must not be installed without a power
stage set.
▶
The mounting bracket should be protected from dirt and moisture during installation.
Note! Degree of protection IP 65 is only applicable if
-
the inverter is placed in the mounting bracket and permanently attached using
screws
，
- the cover for the data communication area is permanently attached to the inverter
with screws.
Degree of protection IP 20 applies to the mounting bracket with no inverter and the vent-
ing duct.
Selecting wall
plugs and screws Important! Different fixings may be required to fit the mounting bracket depending on the
type of underlying surface. Fixings are therefore not included in the scope of supply of
the inverter. The installer is responsible for selecting the right type of fixing.
Recommended
screws To install the inverter, the manufacturer recommends the use of steel or aluminium
screws with a diameter of 6 - 8 mm.
Opening the
inverter
WARNING!
Danger from inadequate ground conductor connection.
This can result in serious injury and damage to property.
▶
The housing screws provide a suitable ground conductor connection for grounding
the housing and must NOT be replaced by any other screws that do not provide a
reliable ground conductor connection.
