Installation / Removal
You may only connect the unit when the voltage is off. For the installation, ob-
serve the 5 basic principles of electrical engineering: Isolate, secure against
restart, verify the absence of voltage, short circuit, cover adjacent parts that
are live.
• Slide the two terminal covers (2) towards the display of the device and install.
- First place the energy meter on the 35 mm rail with the upper rail support in the correct
position.
- Push the meter onto the rail until it clicks into place. The energy meter is xed.
• In order to remove the meter, remove the two terminal covers (2).
- Disconnect all connection cables from the terminals.
- Using a slotted screwdriver, press down on the mounting bracket (8) unlock the xture.
Remove the meter from the rail.
Connection
It is important that you read these operating instructions, including the safety
instructions thoroughly and carefully before rst use to ensure that you will
launch the relay board properly!
You may only connect the unit when the voltage is off. For the installation,
observe the 5 basic principles of electrical engineering.
• The energy meter is connected in series. The connections for the line conductor are located
at the bottom (7). The connections for the neutral conductor are located at the top (3).
• Connect the unit at both screw terminals as shown.
• Arrow markers correspond to current direction.
• Insulation on the connection cables at the contact points must be stripped for
min. 8 mm.
• Always use appropriate crimp ferrules with multi-core conductors.
Loosen the screw terminals for the circuit (L/N) with a Phillips screwdriver (size PZ1)
or a slotted screwdriver (size 0.8 x 4.0 mm).
• Insert individual conductors into corresponding terminals and tighten them with the torque
of 0.6 Nm.
• Make sure the conductors are correctly placed in the terminals.
Use of proper screwdriver and correct torque during installation in regards to
the load circuit is essential, since inadequate fastening leads to overheating
and may cause re.
a) S0 interface
• The S0 pulse output is passive and potential-free. The connection must be made with the
correct polarity. Observe the information in the technical data.
• The S0 interface is connected to the screw terminals with terminal code 20 and 21 (4). Use
a suitable slot screwdriver.
• Insulation on the connection cables at the contact points must be stripped for min. 4 mm.
Tighten the terminals with a torque of approx. 0.4 Nm.
• Replace the terminal covers on the unit and slide them towards the fastening rails.
• Seal can be put through the eyelets (1) when the terminal covers are closed. Thus, the con-
nections can be protected against tampering.
The energy meter is only capable of cumulative energy consumption meter-
ing. Therefore, the reverse current will still be detected as forward current
(rewind lock). Please be aware of this when using the meter.
Display
• The energy consumption is indicated on the main display in kWh (kilowatt hour).
• The red light-emitting diode (6) can be used as the metrological constant.
• It ashes with the frequency of 2000 pulses/kWh and can be used like the SO interface for
further data processing with optional measuring accessories.
Getting started
• After successful wiring check, put the energy meter into operation without load.
• Check again all contact points (input/output) for correct voltage values.
• Carry out stepwise load connection.
