The scope of supply of the inverter comprises mounng instrucons. They
describe t
echnical data and informaon on mechanical and electrical installa-
on.
Mounng
posion
•
Vercal alignment - all mains connecons are at the top and the motor connecons at the
boom.
Free spaces
•
Maintain the specied free spaces above and below to the other installaons.
Mechanical installaon
•
The mounng locaon and material must ensure a durable mechanical connecon.
•
Do not moun
t onto DIN rails!
•
In case of
connuous vibraons or shocks use vibraon dampers.
How to mount the inverters onto the mounng plate
1.Prepare mounng plate with corresponding threaded holes and equip them with screws
and, if required, washers.
a)Use screw and washer assemblies or hexagon socket screws with washers.
b)Do not yet ghten the screws.
2.Mount the inverter on the prepared mounng plate via keyhole suspension.
3.Only ghten the screws hand-ght.
4.If required, pre-assemble further units.
5.Adjust the units.
6.Screw the units onto the mounng plate.
The inverters are ready for wiring.
Measures for cooling during operaon
•
Ensur
e unimpeded venlaon of cooling air and outlet of exhaust air.
•
If the c
ooling air is polluted (u, (conducve) dust, soot, aggressive gases), take adequate
countermeasures.
•
Install lters.
•
Arr
ange for regular cleaning of the
lters.
•
If r
equired, implement a separate air guide.
Screw and washer assemblies or hexagon socket screws with washers are recommended..
M5 x ≥ 10 mm for devices up to and including 2.2 kW
M5 x ≥ 12 mm for devices up to and including 11 kW
M6 x ≥ 16 mm for devices up to and including 22 kW
