CT operated energy meter with settable CT ratio and MID.

Maximum current 3x5A. Standby loss 0.5 watt per path only.

Modulair device for DIN-EN 60715 TH35 rail mounting in distribution

cabinets with IP51protection 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 is10mA. 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 of10 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 lightingswitches 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 and1500:5.

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.
