With voltage code "9", separate versions for T1, T2 and T3. For order code
A11, only one output possible in each case.
Utilization according to temperature class F.
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.
The "Second shaft extension" option, order code K16 is not possible.
