3.13 Subsequent paintwork
Attention!
For retrospective painting of the gear unit, the radial seals, rubber elements, pressure venting
valves, hoses, type plates, adhesive labels and motor coupling components must not come
into contact with paints, lacquers or solvents, as otherwise components may be damaged or
made illegible.
3.14 Temperature sticker
The temperature class or the maximum surface temperature can be seen from the ATEX
labelling in the last line of the rating plate.
Examples: II 2G c IIC T4 X or II 3D 125°C X
The temperature sticker must be affixed next to the oil level screw (See Section 6.1) towards the
motor. For gear units with an oil level vessel, the temperature sticker must be affixed in the same
position as for gear units without an oil level vessel. For gear units which are lubricated for life,
without oil maintenance, the temperature sticker should be affixed next to the rating plate.

3.15 Fitting the cooling coil to the cooling system
The cooling coil is recessed into the housing cover (See Item 2, Figure 3-16). Cutting ring screw
threads (see Item 1, Figs. 3-16) are located at the casing cover for the connection of a pipe with
an external diameter of 10 mm according to DIN 2353. Remove the drain plug from the screw
neck prior to assembly to avoid any contamination of the cooling system. The screw necks
should be connected with the coolant circuit, which must be provided by the operator. The flow
direction of the coolant is irrelevant.
Danger!
With temperature class T4 gear units with a maximum surface temperature of less than
135°C the supplied self-adhesive temperature sticker (printed with value 121°C) must
be affixed to the gear unit housing. (Part No.:283 9050).
