1.1 Safety instructions
Information for Your Own Safety
This manual does not contain all of the safety measures for operation of the
LEM022SJ, because special operating conditions, local code requirements or local,
national or international regulations may necessary to take further measures. It does
contain information which must be adhered to in the interests of your own personal
safety and to avoid material damages.
Warning
Means that failure to observe the instruction can result in death, serious injury or
considerable material damage.
Caution
Means hazard of electric shock and failure to take the necessary safety precautions
will result in death, serious injury or considerable material damage.
Qualified personnel
Commissioning and operation of SEP LEM022SJ described in this manual may only
be performed by qualified personnel. Qualified personnel in the sense of the safety
information contained in this manual are persons who are authorized to commission,
start up, ground and label devices, systems and circuits according to safety and
regulatory standards.
Use for the intended purpose
The SEP LEM022SJ may only be used for the application cases specified in the
catalog and the user manual and only in connection with devices and components
recommended and approved by SEP Europe.
Proper handling
The prerequisites for reliable operation of the product are proper transport, proper
storage, installation and assembly, as well as proper operation and maintenance.
When operating electrical equipment, certain parts of this equipment automatically
carry dangerous voltages. Improper handling can therefore result in serious injury or
material damage.
Use only isolated tools.
Do not connect while circuit is live (hot).
Place the meter only in dry surroundings.
Do not mount the meter in an explosive area or exposed to dust, mildew and
insects.
Make sure the used wires are suitable for the maximum current of this meter.
Make sure the AC wires are connected correctly before activating the
current/voltage to the meter.
Do not touch the meter connecting clamps directly with your bare hands, with
metal, blank wire or other material as you will have the chance of an electric
shock and a possible chance for health damage.
Make sure the protection cover is placed after installation.
Installation, maintenance and repair should only be done by a qualified
personnel.

3LEM022SJ 2015 V01
Never break the seals and open the front cover as this might influence the
functionality of the meter, and will be avoid any warranty.
Do not drop, or allow physical impact to the meter as there are high precision
components inside that may break or render the meter measure accurately.

1.9 Operating
Working indication
On the LEM022SJ front panel, there are three power indicating LED which have
different color from each other. The yellow LED represent L1 phase; the green LED
represent L2 phase; the red LED represent L3 phase. When any phases work normally,
the LED representation will be on. When any phases have failure or no power, the LED
will turn off.
Consumption indication
There is a PULSE LED which is used as indicating power consumption in the front panel
of LEM022SJ. When consumption happens, the LED will flash. The more quickly LED
flash, the more consumption there is. For this LED, the flash rate is 400 impulses per
kWh (2.5Wh/imp).

8LEM022SJ 2015 V01
Reverse indication
There is REV. LED on LEM022SJ front plate. When meter load current flow is reverse,
the LED lighten. What does the indication do count down or still stay the same.
Reading the meter
LEM022SJ is equipped with a white backlight LCD display. During the normal working
hours, the backlight will be on all the time. LCD display will show the following energy
data and indication message.
a) Current total energy
When the meter is in normal working, it will display only 7 +1 energy data with.
The unit is kWh. These data cannot be reset to zero by the user. Example: Total
energy is 4574899.1 kWh.

Pulse output
The pulse led on the front of the meter is pulsing when the meter is in use (2,5Wh/inp.).
The LEM022SJ DIN rail energy meter is equipped with an pulse output which is fully
separated from the inside circuit. It generates pulses in proportion to the measured
energy for remote reading purposes and accuracy testing. The pulse output is a
polarity dependant, passive transistor output requiring an external voltage source for
correct operation. For this external voltage source, the voltage (Ui) should is 5-27V
DC, and the maximum input current (Iimax) is 27mA DC. To connect the impulse
output, connect 5-27V DC to connector 26 (anode), and the signal wire (S) to
connector 27 (cathode). The meter pulses 400 per kWh (2.5Wh/imp).
1.10 Troubleshooting
CAUTION
During repair and maintenance, do not touch the meter connecting
clamps directly with your bare hands, with metal, blank wire or other
material as you will have the chance of an electric shock and a possible
chance for health damage.
Turn off and lock out all power supplying the energy meter and the
equipment to which it is installed before opening the protection cover to
prevent the hazard of electric shock.
