energy for remote reading purposes and accuracy testing. The pulse output is a polarity 
dependant, passive transistor output requiring an external voltage source for correct 

operation. For this external voltage source, the voltage (Ui) should is 5-27V DC, and 
the  maximum  input  current  (Iimax)  is  27mA  DC.

 

To  connect  the  impulse  output, 

connect 5-27V DC to connector 20 (anode), and the signal wire (S) to connector 21 

(cathode). The meter pulses 2000 per kWh (0.5Wh/imp).

CAUTION 

 

During repair and maintenance, do not touch the meter connecting clamps 
directly with your bare hands, with metal, blank wire or other material as 
you will have the chance of an electricity shock and a possible chance for 

health damage. 

 

Turn off and lock out all power supplying the energy meter and the 

equipment to which it is installed before opening the protection cover to 
prevent the hazard of electric shock. 

 

WARNING 

 

Maintenance or repair should be performed by qualified personnel familiar 

with applicable codes and regulations. 

 

Use insulated tools to maintain or repair the meter. 

 

Make sure the protection cover is in place after maintenance or repair. 

 

Case is sealed, failure to observe this instruction can result in damage for 
meter. 

 

Problem 

Check 

Solution 

No light for the   
Power supply 
indicator. 

Is AC power supply 
connected to the 
meter ? 

 
Is the 1 and 4 
connecting correct ? 

 
 

 
 
 

Maybe there is a 
fault in the inside 
circuit. 

 

Check switch or circuit-breaker 
and fuse or thermal cut-off. 
 

 
Reinstall terminal screws on the 1 
and 4. Make sure all screws are 

fixed. Than there should be a 
230V 50Hz AC voltage between 

the terminal screws on the 1 and 
4 when power supply is input. 
 

Contact a qualified technician. 
When necessary replace the 
meter.
