Atex Motor Installations - Allen-Bradley MP-Series Installation Instructions Manual

4. Carefully align the flat surface on the feedback or the power/brake cable plug (shown in
the diagram) with the flat surface on the motor connector.
IMPORTANT The motor orientation shown is used to clearly show the alignment marker on each cable socket.
The recommended motor orientation when installed positions the connectors at the bottom of the
motor.

Side
Connector plugs have either a tab or a flat surface with a logo to indicate the alignment point.
5. Hand tighten the collar on the plug to fully seat it on the connector:
•
Threaded DIN (M4) cable plugs require five to six revolutions.
•
SpeedTec DIN (M7) cable plugs require approximately one-quarter of a revolution.
TIP
Do not apply excessive force when mating the cable plug with the motor connector. If the plug
and connector do not go together with light hand force, realign the flat surfaces and try again.
ATTENTION: Align the keyed connectors and hand-tighten the recommended number of turns.
If you cannot tighten the connectors by hand, verify that the keyed connectors are properly aligned.
Do not use tools (for example, pliers and vise-grips) to tighten the connectors.

ATEX Motor Installations

If your motor has an ATEX rating for hazardous environments, complete the following step. The
catalog number on ATEX motor nameplates ends with H, for example MPL-xxxx-xxxxxH.
Verify the continuity and functionality of the thermal switch signals, TS+ and TS-, transmitted
through the feedback cable that connects the motor to its controlling drive.
ATTENTION: It is mandatory that the motion system monitor the thermal switch signals from a
motor requiring an ATEX rating.
The intrinsic safety protection concepts in the ATEX Direction 94/9/EC must be enabled by
connecting the thermal switch signals from the motor to the motion control system.
