06.02. Electrical Installation
• Voltage must be switched off when the rod
reaches the ends of the stroke or if an excessive
load occurs mid-stroke to prevent damage to the
actuator.
• Make sure that the switch can handle the maxi-
mum motor current.

CAUTION!
• Make sure the leads and cables leading to the
motor can handle the maximum motor current.
• For additional protection, use a fuse between the
actuator and the power source.
• Do not work on the actuator or the wiring with the
power switched on!
Wire cross-sections
To avoid malfunctions due to voltage drops, the
cross-section of the wires connecting the actuator
and the power supply must have an appropriate
diameter.
Position feedback power supply
The potentiometer should be powered at 5 VDC. Do
not use a higher voltage.
• Standard output: 0 - 5 VDC ± 3%.
07. Maintenance
The actuator is a closed unit and does not require
internal maintenance. In fact, the actuator is not to
be opened by unauthorized personnel. However,
some external maintenance must be performed on
a regular basis:
• Clean the actuator with a dry cloth to remove dust
and dirt.
• Inspect the actuator for mechanical damage or
wear.
• Inspect the actuator’s attachment points, cables,
rod ends, housing, and connector, and check that
the device works correctly.
