Information
The modules for the IP66 version are identified by an additional "-C" in the model code and were modified with
the following special measures:
•
Impregnated PCBs,
•
Powder coating RAL 9006 (white aluminum) for housing,
•
Modified blank screw caps (UV-resistant),
•
Diaphragm valve for pressure compensation in the event of temperature changes,
•
Low-pressure test.
– A free M12 screw connection is required for low-pressure testing. A diaphragm valve is inserted here after
successful testing. This screw connection is therefore no longer available for the cable inlet.
If the variable frequency drive needs to be retrofitted, i.e. the drive unit (inverter pre-attached to motor)
is not entirely purchased from NORD, the diaphragm valve is supplied in the accessories kit with the
variable frequency drive. The valve must be professionally installed on site by the system installer
(note: the valve must be installed in a location that is as high as possible in order to avoid contact with
accumulated moisture, e.g. standing water due to condensation).

Information
Variable Frequency Drives, size 4, could also be delivered up to week of manufacture 38/2012 (up to ID No.:
38M...) as "coated" versions "-C" but they only comply with IP55 because of the integrated fan. From ID No.:
39M.... these devices are also compliant with IP66.
"SK 2xxE-...-C" devices with output of 5.5 kW and 7.5 kW (230 V), and 11 kW and 15 kW (400 V) from ID No.:
28M... compliant with IP66.

Information
Diaphragm valve
The diaphragm valve (accessories kit with the IP66 version of the variable frequency drive connection
unit) enables the compensation of pressure differences between the inside of the variable frequency
drive and its environment and also prevents the entry of moisture. If it is mounted in an M12 screw
gland of the inverter connection unit, make sure that the diaphragm valve does not come into contact
with standing water.
