MP-Series Heavy-duty Electric Cylinders
Build and Route Cables
Knowledgeable cable routing and careful cable construction improves system electromagnetic
compatibility (EMC).
To build and install cables, perform these steps.
1. Keep wire lengths as short as physically possible.
2. Route signal cables (encoder or serial) away from motor and power wiring.
3. Separate cables by 0.3 m (1 ft) minimum for every 9 m (30 ft) of parallel run.
4. Ground both ends of the encoder cable shield and twist the signal wire pairs to prevent
electromagnetic interference (EMI) from other equipment.
ATTENTION: High voltage can be present on the shield of a power cable, if the shield is not
grounded.
Make sure there is a connection to ground for any power cable shield.
Failure to observe these safety precautions could result in personal injury or damage to equipment.
Install the Electric Cylinder
The installation must comply with all local regulations and use of equipment and installation
practices that promote electromagnetic compatibility and safety.
ATTENTION: Unmounted electric cylinders, disconnected mechanical couplings, and disconnected
cables are dangerous if power is applied.
Appropriately identify (tag-out) disassembled equipment, and restrict (lock-out) access to
electrical power.
Failure to observe these safety precautions could result in personal injury.
Follow these steps to prepare the electric cylinder for installation on the machine.
1. Provide sufficient clearances in the area of the electric cylinder for it to stay within its
specified operating temperature range.

Specifications
electric cylinder unless forced air is blown across the electric cylinder for cooling. Keep
other heat producing devices away from the electric cylinder.
2. Make sure the mounting surface supports the electric cylinder evenly so that it is free of
mechanical stress and distortion.
•
Evenness of the mounting surface must be within 0.127 mm (0.005 in.).
•
The thrust rod must be parallel to the guide within 0.0254 mm (0.010 in.).
