10.1
Maintenance
The actuators of the series
NE
are maintenance free.
Check on an approximately six monthly cycle, that the device is dry inside, at least after 1/2 year.
In the case of an actuator which is open and ready to operate, when tools are being used (for
example small screwdrivers, forceps, etc.) there is the risk that you may touch live parts (up to
230V AC) and thus receive a shock.
In the event of a defect in the actuator, make contact with the manufacturer. The telephone
number will be found on the inside front cover of these mounting and operating instructions.
Open the housing cover by loosening the 4 screws and pulling the housing cover hard to remove
it. In this context, see:
6.2.1 „Removing the housing cover“
If you find moisture in the interior of the device, attempt to find the cause for this and eliminate it.
• Is the moisture condensation?
• Is the circumferential rubber sealing ring damaged?
• Do the metric screw fittings leak?
• Are there cracks in the housing or the housing cover?
If you determine that there is damage to the actuator, isolate the device from the power supply.
However, before doing this, it is essential to refer to chapter:
3 „Safety advice“
10.2 Cleaning
Clean the housing of the actuator as required using a slightly moistened, soft cloth and a normal
household cleaner.
Do not use any abrasive, corrosive or flammable cleaning agents.
Do not use any high-pressure cleaning devices.
Prevent moisture or liquid penetrating into the interior of the device
