PACKAGING, STORAGE AND MAINTENANCE

 

2.1

 

Packaging 

The packaging of AT SWITCH actuators is comprised of a dual-layer 
cardboard box strapped on a pallet. For certain non-EU countries or 

on  request,  the  pallets  are  heat  treated  to  standard  NIMP 15  and 

IPPC stamped.  
This  packaging  is  identical  for  shipping  by  road, air or  sea,  unless 

otherwise indicated in the contract. 

2.2

 

Storage 

Actuators should be stored under a shelter, in a clean and dry place, 

and protected from wide temperature variations. 

 

 

Avoid placing the actuator directly on the floor. 

 

Check that the plugs on cable entries are correctly tightened. 

 

Check that the cover screws are correctly tightened to ensure 

weatherproof sealing of the cover. 

AT SWITCH actuators include electrical components and lubricated 

gear stages. Even with a weatherproof enclosure, oxidation, galling 
and other alterations may occur if actuators are not correctly stored. 

What to check after storage 

1.

 

Visually check the electrical equipment. 

2.

 

Manually operate micro switches, buttons, selectors, etc., to 

ensure their proper mechanical function. 

3.

 

Manually operate the actuator for a few travels. 

 

The heating resistance should be connected to the power supply, 

especially if the storage place is humid.
