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.
Follow these steps to install the electric cylinder.
1.
Provide sufficient clearances in the area of the electric cylinder for it to stay within its
specified operating temperature range.
Refer to
for the operating temperature range. Do not enclose
the 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.
The evenness of support surface should be
0.2 mm (0.008 in.).
ATTENTION: Unmounted electric cylinders, disconnected mechanical couplings, and disconnected
cables are dangerous if power is applied.
Disassembled equipment should be appropriately identified (tagged-out) and access to electrical
power restricted (locked-out).
Failure to observe these safety precautions could result in personal injury.
ATTENTION: Make sure that cables are installed and restrained to prevent uneven tension or
flexion at the cable connectors.
Excessive and uneven lateral force at the cable connectors may result in the connector’s
environmental seal opening and closing as the cable flexes.
Failure to observe these safety precautions could result in damage to the electric cylinder motor
and its components.
ATTENTION: Damage may occur to the electric cylinder bearings and the feedback device if a
sharp impact to the piston rod is applied during installation. Do not strike the piston rod with tools
during installation or removal.
Do not attempt to rotate the piston rod during installation. Rotating the piston rod will break the
mechanism that allows the electric cylinder to extend and retract.
Failure to observe these safety precautions could result in damage to the electric cylinder and its
components.
IMPORTANT
Position the electric cylinder so that all of the operating parts are accessible and the
breather port is not covered.
ATTENTION: Do not modify the settings of the screws and the threaded pins.
The electric cylinder must not be fastened by the front cover alone when used with high
loads.
Heavy tensile strain may cause the screws in the cover to pull out.
