Motor components and options
5.2 Options
• Attach the twist protection provided for the signal connector in compliance with regulations.
• Use Ex-certified cable glands for the power connection. Close and seal unused threads using
Ex-certified screw plugs.
• The thermal stability of the connecting cables must be at least 80 °C. Plastic-insulated,
flexible cables must have the same durability as heavy-duty, rubber-insulated cables.
SIEMENS MOTION-CONNECT power and signal cables meet these requirements.
• The motors have a ground connection at the bearing shield/enclosure. Additionally ground
the motors at this connection point.
• Belt drives are only permissible if buildup of a static charge is ruled out in the machinery.
• Do not repaint/touch up explosion-proof motors. However, if this is required, then comply
with the following requirements:
– Limit the surface resistance of the paint used: Surface resistance ≤ 1 GΩ for motors
– Breakdown voltage ≤ 4 kV for device group III
• Contact Technical Support (Chapter "Introduction") for the correct paint structure.
Note
For additional information, please contact Technical Support or your local sales partner.
Design criteria for shaft heights 180 to 225
The motors with option M39 can be selected with the following article number suffix.
1PH818x-1Ax1x-xxx1-Z, Z=M39
1PH818x-1Ex1x-xxx1-Z, Z=M39
1PH818x-1Hx1x-xxx1-Z, Z=M39
1PH818x-1Jx1x-xxx1-Z, Z=M39
1PH818x-1Mx1x-xxx1-Z, Z=M39
1PH822x-1Ax1x-xxx1-Z, Z=M39
1PH822x-1Ex1x-xxx1-Z, Z=M39
1PH822x-1Hx1x-xxx1-Z, Z=M39
1PH822x-1Jx1x-xxx1-Z, Z=M39
1PH822x-1Mx1x-xxx1-Z, Z=M39
The listed motors cannot be supplied with the Performance bearings (14th data position =
"L").
1PH8 motors, shaft heights 180 and 225 with option M39 are implemented with insulated
NDE bearings as standard.
