5.  Mounting

 ·The device meets the operating conditions ac-

cording to DIN IEC 60721-3-3 and is intended 
for weather-protected, stationary use. 

 ·Mount the meter in switch cabinets or small 

distribution boards according to DIN 43880. 
The device is to be mounted on a 35-mm 
mounting rail to DIN EN 60715. 

Fig. Device on mounting rail to DIN EN 60715.

5.1 

Mounting orientation

•  The mounting orientation is arbitrary. 

•  Forced ventilation is not required 

ATTENTION

Material damage due to improper handling or 

disregard of the assembly instructions!

Disregard of the installation instructions can dam-

age or destroy your device.

 ·

Use suitable mounting rails according to DIN 

EN 60715 for mounting the meter! 

 ·Provide adequate air circulation in your installa-

tion environment and, as needed, cooling when 

the temperatures are high.

5.2 

Installation location

DANGER

Danger of electric shock!

Electric shocks lead to serious injuries, including 

death.

 ·Disconnect your system from the power supply 

before mounting and connecting the device!

 ·Secure it against being switched on!

 ·Check to be sure it is de-energized!

 ·Ground and short circuit!

 ·Cover or block off adjacent live parts!

 ·The installation must only be carried out by 

qualified personnel with electrical training!
