ASSEMBLY, OPERATION
1. Disconnect the safety power supply
circuit, the overcurrent circuit breaker
or the isolating switch connected to the
corresponding water circuit.
2. Check voltage-free condition on the
supply cables with proper instru-
ment.
3. Install LEM-04 in the switchboard on
TH 35 (DIN) rail.
4. Connect the wires to the terminals in
accordance with the wiring diagram.
5. Switch on the power supply.
Current flowing throught the device
causes that generated pulses are propor-
tional to amount of drawn electric energy
(2000 pulses per kWh). A flashing LED in-
dicates current consumption and the fact
that the device is measuring. The value
can be read from segment LCD. The
digits after the decimal point indicate the
hundredths of 0.01 kWh (10 Wh).
NOTES:
• When using pulse input (terminals
20, 21) it is necessary to apply addi-
tional supply voltage within a range
5 ÷ 27 V DC.
• It is recommended to use an addi-
tional resistor R (470 Ω ÷ 1 kΩ) to
limit the value of current.
• Changing the power supply polarity
may damage the indicator’s pulse
output.
• If there is no connection then the
metering device should not be con-
nected to pulse output of the supply
system.
