MOUNTING INSTRUCTIONS IN STEPS

Before you start mounting the STR-3, read carefully 

Safety and Precautions

 and 

follow these steps. Choose a smooth solid surface for installation (a wall, panel, 
etc.).

Follow these steps:

1. 

 Open the door of the controller. Mind the wires that connect the rotary switch 
with the autotransformer. The mounting holes are on the inside back panel of the 
enclosure and are covered with blanking plugs. 

2. 

 Mount the enclosure using corrosion resistant screws or bolts.  Mind the correct 
mounting position and unit mounting dimensions (see 

Fig. 1

 

Mounting dimensions 

and 

Fig. 2

 

Mounting position

). 

3. 

 Pay attention to following instructions in order to minimize the operating 

temperature:

3.1 

 Respect the distances both between the wall / ceiling and the device and 
between  two devices as shown in 

Fig. 2. 

In order to ensure sufficient 

ventilation of the controller, clearance on every side has to be maintained.

3.2 

 When installing the device, please keep in mind that the higher you install  
it, the warmer the device will get. For example, in a technical room the 
correct installation height can be of great importance. 

3.3 

 If maximum ambient temperature cannot be adhered to, please provide 
extra forced ventilation / cooling. 

Not respecting the abovelisted rules can reduce service life and relieves the 

manufacturer of any responsibilities.

4. 

 Once secured in position, the mounting screws or bolts should be sealed to 
maintain the IP rating of the enclosure.
