ENTES EVM-35 User guide
General Information
EVM-35 is designed to measure the phase-phase voltage, phase neutral voltage
of system.
Application of EVM-35
1) It can measure voltage for each phase in 3 phase
systems with neutral and without neutral.
2) Voltage transformer primer ratio (1-40000) and seconder ratio (1-300) can be
programmed
.
3)
A password can be arranged from PASS CodE menu in order to prevent
change of the setting by unauthorized person.
Precautions For Installation And Safe Use:
- Failure to follow those instructions will result in death or serious injury.
- Disconnect all power before working on equipment.
- When the device connected to the network, do not remove the back panel
- Do not try to clean the device with solvent or the like.Only clean the device
with dried cloth.
- Verify correct terminal connections when wiring.
- Electrical equipment should be serviced only by your component seller.
- Only for rack panel mounting.
- The fuse should be used F type and current boundary value must be 6A.

Voltage transformer ratio:
Primary and secondary values of Voltage Transformer ratio can
be programmed in this menu.
Note: Enter the primary value as 00100 and secondary value as
100 if there is no voltage transformer is used between EVM-35
and system.
For example;
If there is 34500V/100V voltage transformer is used
between EVM-35 and system;
Primary voltage transformer value = 34500,
Secondary value = 100 is set.
Programming the primary value for voltage
transformer:
Primary value for voltage transformer is programmed in this
menu. This value can be entered between 1-40000.
In order to enter the voltage transformer primary value; press
SET button for 3 sec. in measurement mode
