1. Safety notice
The smart energy meter of EM535 series does not require special mechanical or electrical
tools for its installation. Mounting position (with any angle of tilt) has no effect on the
measurement functions of the meter.
Connecting of the meter must be made according to applicable wiring diagram. Incorrect
connection of the meter to the electricity network causes major display problem and can
also causes serious damage to the meter. Before starting meter operation, it must be
ensured the local conditions of the energy system are consistent with data on the nameplate
of the meter. Preferably use for the connection of shielded cables. Make sure that
connecting cables are not damaged during installation of the meter are not energized and
free of non-mechanical stress.
Repairs when removing the cover of the meter, which is also under tension can be made
only by a qualified electrician who is familiar with the associated risks. Capacitors in the
meter may still be charged even if the meter is disconnected from all energy sources.

The smart energy meter is equipped with 6+1 LCD display, which is used as recording
consumption and can’t be reset to zero. The number system is based on units of 10. And
unit is kWh. Another way through RS485 and PC software can read power consumption
Meters have four status: self-inspection status, cycle display status ,button press
display and program status.
Self-inspection status：meters will come into self-inspection status after connect
with electricity. include: full screen、software version number. every screen
display time is 1 second.

7.3 Pulse output
Smart din rail energy meter is equipped with a pulse output which is fully separated from
the inside circuit. That generates pulses in proportion to the measured energy. They are test
pulse output (pins 20 & 23). Usually, the test pulse output is used as testing accuracy or
reading purpose in close quarters.
The test 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
be 5-27V DC, and the maximum input current (Imax) should be 27mA DC. To connect the
impulse output, connect 5-27V DC to connector 23 (anode), and the signal wire (S) to
connector 23 (cathode). The meter pulses is indicated on the front panel.
7.4 Communication port
Smart meter has equipped communication port, we can program the meter’s operation data
or reading via these 2 ports.(Pin26 pin27) . There are two options for the communication
com，RS485 or M-bus.

Remars：
1. Type 535.3.2 &535.4.2 series meters , default baud rate will be 1200bps
2. Type 535.3.3 &535.4.3 series meters , default baud rate will be 2400bps
3. 300bps /1200/2400bps /9600bps can be set
4. Type 535.3.1&535.4.1 series meters without communication function do not
have the setup interface
8.4 CT rate setting
Press “Page down” and “page up” buttons to select the CT transformation ratio
press “SET” button to save the setup. the interface will enter Password setup.

2,after the CT ratio setup, the energy consumption display will be reset to 0.
 Password setting：
The meter will display the current password after enter the password setup
interface, press the “SET” to change the password. Use “page dow” and “page up”
button to input password as you want. After 30 seconds the meter will save the
password you changed.
Remarks:
1 Do not forget the password you setup.
2 Please press the button to check if every setup is correct after the program.
