Oldal 1/2
CT operated three-phase energy meter with settable CT ratio and MID.
Maximum current 3x5A. Standby loss 0,8W at L1 and only 0,5 W at L2
and L3 each.
Modulair device for DIN-EN 60715 TH35 rail mounting in distribution cabinets
with IP51 protection class.
4 modules = 70 mm wide and 58 mm deep.
Accuracy class B (1%). With RS485 interface.
This three-phase energy meter measures active energy by means of the
current between input and output.
The internal power consumption of 0,8W or 0,5 W 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 10 mA.
The terminals L1 and N must always be connected.
Connection via a FBA14 to the Eltako RS485 bus with a 2-wire shielded
bus cable (telephone cable). The meter reading and the momentary capacity
are transferred to the bus – e.g. for transfer to an external computer of the
GFVS 3.0 Software – and is also transferred to the wireless network via the
FAM14. Display also using FEA65D.
The 7 segment LC display is also legible twice within a period of 2 weeks
without power supply.
The power consumption is displayed with a LED flashing 10 times per kWh
next to the display.
On the right next to the displa y 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 operation 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.
A device address for the DSZ14 has to be assigned from the FAM14, to hand
the telegrams of the DSZ14 over to the bus.
Assign device address for the DSZ14:
Normal display: Briefly press the SELECT button, the backlight is switched on.
If the SELECT button is pressed longer than 3 seconds, the device address
appears in the display. Now turn the rotary switch on the FAM14 to position
1 within 60 seconds, its lower LED flashes red. Once the address is assig-
ned by the FAM14, its lower LED lights green for 5 seconds and the normal
display appears again on the DSZ14.
Delete device address of the DSZ14:
Normal display: Briefly press the SELECT button, the backlight is switched
on. If the SELECT button is pressed longer than 3 seconds, the device
address appears in the display. Now hold the SELECT button for 5 seconds,
the device address is set to zero.
Transmit teach-in telegram:
Normal display: Briefly press the SELECT button, the backlight is switched
on. If the SELECT button is pressed longer than 3 seconds, the device
address appears in the display.
By briefly pressing the MODE button, a teach-in telegram and a data tele-
gram is sent. The FAM14 has to be operated in position 2 or 5, to sent the
telegrams of the DSZ14 into the Eltako Wireless Building.

1) The carrying capacity of cables and wires is defined in DIN VDE 0298-4.
2) The torques for screw terminals are mentioned in DIN EN 60999-1.
To avoid damages at the energy meter, the recommended torque values for each terminal
must not be exceeded!

A data telegram containing meter reading, power and serial number is auto-
matically sent and cyclically transmitted every 10 minutes after switching on
the supply voltage.
If you change the meter reading by 0.1 kWh, the meter reading telegram is
sent.
Within 20 seconds after a change in power of at least 10%, a power telegram
is sent.
The DSZ14 can be read-out with the PC tool PCT14.
The serial number, meter reading and resettable meter reading will be
displayed.
Typical connection:
4-wire-connection 3x230/400 V
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.
