Order other types of construction with type of construction code
9 in the final position and the corresponding order code (see
"Special versions" in the "Selection and ordering data" under
"Types of construction").
1) Utilization according to temperature class F.
2) With voltage code "9", separate versions for T1, T2 and T3. For order code
A11, only one output possible in each case.
3) 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.
4) If motors 1MA6 183-... to 1MA6 318-... (motor series 1MA6 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.
5) 1MA6 220-... to 1MA6 318-... motors (motor series 1MA6 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.
6) The "Second shaft extension" option, order code K16 is not possible.
7) Type of construction IM V3 is only possible using type of construction code
9 and order code M1G.
