INSTRUCTIONS OJ-DV | Installation

11. Mechanical installation

Warning

Incorrect mechanical installation may cause overheating and impaired performance.

• OJ-DV must only be installed by trained/experienced personnel.

• To ensure proper cooling of the OJ-DV, it must be positioned in such a way that the passing air

ﬂow (> 3 m/s turbulent air speed) can cool the OJ-DV cooling ﬁns. (3 m/s turbulent air speed is

equivalent to 6.5 m/s laminar air speed). If the OJ-DV is installed in a reduced air ﬂow (< 3 m/s

turbulent air speed) or mounted outside a direct airstream, the output power (kW) will be reduced.

External on-board cooling fan can be added.

• Only OJ-DV-1013 can be installed without considering the above requirements for sucient air

ﬂow over the cooling ﬁns. OJ-DV-1013 is supplied with extra large cooling ﬁns and can therefore

be mounted in still air with an air temperature of max. 40°C.

See Section 25: Technical Speciﬁcations.

• To facilitate future service and maintenance tasks, ensure that there is sucient space around the

unit after it has been installed.

• To achieve the speciﬁed enclosure rating, the cable glands must not point upwards (see ﬁg. 11.2).

• To prevent water from entering OJ-DV via cables and cable glands, ensure that connection is

performed in such a way that water is prevented from accumulating around the cable in the gland.

See ﬁg. 11.3.

• Check that the surface to which OJ-DV is attached is capable of supporting the entire weight of

the unit.

• OJ-DV can be mounted vertically, horizontally or at an incline. See ﬁg. 11.2.

• OJ-DV must be installed on a ﬂat solid surface.

• To avoid unnecessarily long motor cables (max. 5 m), OJ-DV should be installed as close to the

motor as possible.

• Use only the pre-cut installation holes/screw holes to secure OJ-DV in place.

• Dimensioned drawings, see ﬁgs 10.2 to 10.6.

• The OJ DV is not intended to be installed in direct sunlight. The plastic cover and glands are not

UV resistance approved. For installation outdoor it shall be ensured that the DV is protected from

direct sunlight.

• For guidance for a UV cover the sketch below can be used.
