- Maximum surface temperature
Acc. to classification level T4; 135 °C

Special conditions of use

• Do not separate the electrical connector on the valve when energized (The connection is marked “Warning – Do not
separate when energized”).

• The valve shall be installed in a location where it is unlikely to be exposed to impact above 4 Joule.

• The valve shall through the cooling /pipe system be connected to ground.

• The valve shall be powered by a step motor driver, supplying a current controlled signal of nominally 600 mA RMS, not
exceeding 700mA RMS, and max AC voltages 48, supply from an SELV voltage per EN60079-14 §6.3.5.

• The Stepper motor driver must include a transient protection not exceeding 140 % of the peak rated voltage value at
the supply terminals to the equipment.

• The valves shall only be used in the ambient temperature range -40°C ≤ T

If the applied power cable and connector assembly has a specified ambient temperature which is lower than

ambient temperature range -40°C ≤ T
the limited ambient temperature range specified for the cable assembly.

• The applied cable assembly must be fitted with an appropriate M12 connector according to standard EN 61076-2-101.

• The applied cable assembly must be suitable for installation in environments where it is intended to be used and rated
at least IP54.

• The connector shall be evaluated for 2G IIB and be rated for 2 A and 60 V AC or DC.

• The lock nut at the socket / connector shall be tightly screwed to the valve, so that it is no longer possible to
disconnect the plug without tools. The tightening torques is recommended to be between 1.2 Nm and 1.5 Nm or as
specified by the manufacturer of the cable assembly.

• The valve connector must be protected by a protective cap that provides at least IP 54 protection of the connector
when not in use / service.

• The cable assembly shall be fixed properly when installed to protect it against mechanical damage. Max. bending
angle of wires when installed in cold conditions must be considered as specified by the manufacturer of the cable
assembly.

• The internal is hermetically sealed when installed in accordance to Danfoss instructions and not considered as ignition
source in normal operation. The motor shall therefore only be operated in hermitic sealed cooling system where no
flammable atmosphere is present. The oxygen shall always be above the UFL for the fluid.

• The upstart procedure for the sealed cooling system, using flammable fluid and where the valve is installed shall follow
the procedure in EN378-2 and for maintenance the procedure in EN378-4 is relevant.

• The valve may not be used in systems where the system pressure can drop below the ambient environment pressure
as this will increase the risk for oxygen entering into the system in an abnormal situation (leakage in the system).

≤+70°C actual for the valve, then the valve with cable shall only be used within

amb

≤+70°C .
