FIELD INSTALLATION 

Mounting a PowerScout Meter 

Once your PowerScout meter is set up for the desired communication method and protocol, it’s ready to 

install out in the field. 
 

PowerScout

 

meters must be installed in an approved electrical panel or enclosure using proper 

installation practices according to the local electrical codes.  

 

The raw board of the PowerScout 24 meter can be mounted to customer-provided standoffs or 

placed into a NEMA (National Electrical Manufacturers Association) box. A NEMA-rated box is 
available through DENT Instruments. Securely mount the PowerScout meter near a dedicated 

circuit disconnect breaker.  

 

 

 

 

 

 

 

 

WARNING!

 Remove the meter from all sources of voltage before mounting. 

PowerScout 24 mounted in a NEMA-rated box
