Safety Instructions for Mounting

2.2.2

Mounting on a Wall or a Horizontal Surface

The following steps are necessary:

»

Carefully measure and mark the position of the required screw holes to match the

position of the mounting holes on the NL31.

»

Drill the screw holes for the M5 pan-head screws at the marked location.

»

Secure  the  M5  pan-head  screws  at  the  marked location, making sure to leave at

least the following gap between the surface and the screw head:

-

5 mm

»

Place the NL31 so that the wide openings of the mounting holes are over the screw

heads (1). 

Risk of Damages or Injuries

Make sure that the cabinet or the wall where you want to install the 

system supports the weight of the system.

Risk of Fire Through Overheating

Make sure that the equipment does not overheat. Overheating can cause 

fire or malfunction of the device. Conformity to standards expires.

Mount the equipment only in the mounting position described in this 

document.

Adhere to the environmental conditions specified in the Technical Data.

Leave enough space to the sides of the system that are needed for 

cooling to enable the required airflow as specified in chapter Cooling 

Concept.

Do not install the system near any heat sources (e.g., radiators, heaters).

Risk of Damage Through Liquids

Keep the system away from liquids. Avoid exposure to dripping or 

splashing.

The necessary length of the M5 screws to mount the NL31 depends 

on the structure of the surface.
