5.7.13 Control System bp308 and Frequency
Inverter together in one Cabinet
The control cabinet is made of painted sheet steel. The wall-mounted
cabinets have holes on the back to fix them or thread bolts to which
the mounting plates included in the delivery can be attached .
Standing cabinets are mounted on the supplied feet or a pre-made
frame.
They are placed an upright position so that the ventilation slots are
clear. Please ensure that sufficient sound proofing is installed
between the cabinet and the building in critical environments. In such
cases, all contactors and the entire mounting plate inside the cabinet
can be delivered with sound proofing already installed .
A sound pressure level of approximately 55 db (A) was measured at
our standard control cabinets with closed doors and the control sys-
tem bp308 at a distance of around 1 m and 1.6 m height. This corres-
ponds to a sound level somewhere between a turned-down radio [40
db(A)] and a normal conversation [60 db(A )].
The cables enter at the bottom of the cabinet. Please use the cor-
rect cable connections.
The cable duct (optional) for the ingoing lines and cables can be
removed if necessary for easy insertion.
Control cabinet:
• Enclosed (DIN 41488)

• Mains contactors insulated by rubber-bonded metal buffers
