NORDAC FLEX (SK 200E ... SK 235E) – Users Manual for Frequency Inverters
IP66 version:
The IP66 version is a modified option of the IP55 version. Both installation types (motor-integrated,
close coupled) are also available for this version. The modules available to the IP66 design (adapter
units, technology units and customer units) have the same functionalities as the corresponding IP55
design modules.

Information
The modules for the IP66 version are identified by an additional "-C" in the type key, and are modified with the
following special measures:
• impregnated PCBs,
• Powder coating RAL 9006 (white aluminium) 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. After successful testing, a diaphragm
valve is inserted here. This screw connection is therefore no longer available for a cable gland.
If the frequency inverter is going to be retrofitted, i.e. the entire drive unit (inverter pre-attached to
motor) is not being purchased from NORD, the diaphragm valve is supplied in the bag enclosed with
the frequency inverter. 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
Up to week of manufacture 38 / 2012 (up to ID no. 38M...), size 4 frequency inverters are also available as
"coated" versions "-C", but they only fulfil 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... already compliant with IP66.
