CT operated energy meter with settable CT ratio and MID.
Maximum current 3x5 A. Standby loss 0.5 watt per path only.
Modulair device for DIN-EN 60715 TH35 rail mounting in distribution
cabinets with IP51 protection class.
4 modules = 70mm wide and 58mm deep.
Accuracy class B (1%). With SO interface as standard.
This three-phase energy meter measures active energy by means of the
current between input and output.
The internal power consumption of 0.5 watt active power per path is neither
metered nor indicated.
1, 2 or 3 phase conductors with max. currents up to 5A can be connected.
The inrush current is 10mA. The N terminal must always be connected.
The 7 segment LC display is also legible twice within a period of 2 weeks
without power supply.
Power consumption is shown by a bar flashing at a rate of 10 times per kWh.
On the right next to the display are the keys MODE and SELECT. Press them
to scroll through the menu. First the background lighting switches on. The
display then shows the total active energy, the active energy of the resettable
memory as well as the instantaneous values of consumption, voltage and
current per phase.
The CT ratio can also be set. It is set to 5:5 at the factory and blocked with a
bridge over the terminals which are marked with 'JUMPER'. To adjust the CT
ratio to the installed transformer, remove the bridge and reset the energy meter
according to the the display guide, right on this manual. Then block it again
with the bridge. Adjustable current transformer ratios: 5:5, 50:5, 100:5,
150:5, 200:5, 250:5, 300:5, 400:5, 500:5, 600:5, 750:5, 1000:5,
1250:5 and 1500:5.
Error message (false)
When the phase conductor is missing or the current direction is wrong 'false'
and the corresponding phase conductor are indicated on the display.
Important ! Before working on the current transformers disconnect the voltage
paths of the energy meters.

Typical connection:
4-wire-connection 3x230/400V
Connect the current transformer terminals on the secondary part to the
phase cunductors which are metered. These connections for the voltage
supply of the energy meters must be secured according to the local
installation regulations.
