Miscellaneous

Cable duct in the floor below the cabinet
You can make a cable duct below the 500 mm wide middle part of the cabinet. The cabinet
weight lies on the two 50 mm wide transverse sections which the floor must carry.
Prevent the cooling air flow from the cable duct to the cabinet by bottom plates. To ensure
the degree of protection for the cabinet, use the original bottom plates that were delivered
with the unit. With user-defined cable entries, take care of the degree of protection, fire
protection and EMC compliance.

Ventilation
The air inlets of the installation space must supply a sufficient volume of cooling air. For
the minimum air flow values, refer to
PVS800-57B central inverters hardware manual
(3AXD50000048300 [EN]).
WARNING! Make sure that the incoming air is sufficiently clean. If not, dust goes
into the cabinet. The outlet filter on the cabinet roof prevents dust from going out.
The collected dust can cause inverter malfunction and danger of fire.
