The following applies for explosion-proof motors: In the case of the types
of construction with shaft end down, the version "with protective cover" is
required. For types of construction with shaft extension pointing upwards,
a suitable cover must be implemented to prevent small parts from falling
into the fan cover (see the standard IEC/EN 60079-0). The cover must not
block the cooling air-flow.
If motors 1LG6 183-... to 1LG6 318-... (motor series 1LG6 frame sizes
180 M to 315 L) in types of construction with feet IM B6, IM B7 or IM V6
are fixed to the wall, it is recommended that the motor feet are supported.
1LG6 220-... to 1LG6 318-... motors (motor series 1LG6 frame sizes 225 S
to 315 L) are supplied with two screw-in eyebolts in accordance with IM B5,
whereby one can be rotated in accordance with IM V1 or IM V3. It is important
to note that stress must not be applied perpendicular to the ring plane.

Type of construction IM V3 is only possible using type of construction code
9 and order code M1G.
The "Second shaft extension" option, order code K16 is not possible.
Type of construction IM V6 is only possible using type of construction code
9 and order code M1E.
2-pole motors in 60 Hz version available on request.
