General information
EPM-04/04C/04CS is designed for measuring Phase current, frequency, neutral
current and voltages (Phase-Phase and Phase-Neutral) in a
3-Phase system.
EPM-04C/04CS;
Device has 2 warning output which named as Out1 and Out2. (NO-Normally
Open) Please refer to “Output” menu for the functions of the relays.

1  ....... Phase LEDs:The LEDs turn on when the voltage value, which is applied 
to one of the current inputs, reach 30 V
 
2  ....... First display’s k LED (for L1). Measurement parameter is the unit of kilo 
when LED is turned on. ie: kA, kV
3  ....... Display for L1.
4  ....... Second display’s k LED (for L2). Measurement parameter is the unit of kilo
when LED is turned on. ie: kA, kV
5  ....... Display for L2.
6  ....... Third display’s k LED (for L3). Measurement parameter is the unit of kilo 
when LED is turned on. ie: kA, kV
7  ....... Display for L3.
8  ....... Displays network frequency when Hz LED is turned on.
9  ....... k LED for neutral current. Measurement parameter is displayed in unit of 
kilo when this LED is turned on.
10 ....... Display for neutral current and frequency (for EPM-04C/04CS).
11 ....... First warning output LED (Out1). Turned on when the output is activated.
12 ....... Second warning output LED (Out2). Turned on when the output is activated.
13 ....... Over current / voltage warning output for L1. (EPM-04C/04CS)
14 ....... Low current / voltage warning output for L1. (EPM-04C/04CS)
15 ....... Over current / voltage warning output for L2. (EPM-04C/04CS)
16 ....... Low current / voltage warning output for L2. (EPM-04C/04CS)
17 ....... Over current / voltage warning output for L3. (EPM-04C/04CS)
18 ....... Low current / voltage warning output for L3. (EPM-04C/04CS)
19 ....... Over current / frequency warning output for frequency and neutral current
(EPM-04C/04CS).
20 ....... Low current / frequency warning output for frequency and neutral current 
(EPM-04C/04CS).
21 ....... Monitoring the L1, L2, L3 voltages values when V LED is turned on and 
displays the frequency in 4th display.
22 ....... Monitoring the L1, L2, L3 currents values when A LED is turned on and 
displays the neutral current in 4th display.
23 ....... Indicates the activating delta connection when   is turned on. Neutral 
current protection is disactivated even if is activated.
24 ....... H LED for max. instant current and voltage. Max. instant currents and 
voltages are displayed when this LED is turned on.
25 ....... L LED for min. instant current and voltage. Min. instant currents and 
voltages are displayed when this LED is turned on.
26 ....... M LED for max. demand. Max. demand values are displayed when this 
LED is turned on.
27 ....... SET button. It is used to enter into the menu and to save the values.
   If SET button is pressed for 3 sec. in the measurement mode, you can 
   enter into menus. This button is used for monitoring the max. (H), Min. 
   (L) current values and max. demand values in measurement mode.
28 ....... Downward selection button.
29 ....... Upward selection button.
30 ....... ESC button. Escaping from the menu. And also used for switching off the 
Latch function while this function has activated.
Failure to follow those instructions will result in death or serious injury.
- Disconnect all power before working on equipment.
- When the device is connected to the network, do not remove the front
  panel.
- Do not try to clean the device with solvent or the like.Only clean with dry
  cloth.
- Verify correct terminal connections when wiring.
- Electrical equipment should be serviced only by your component seller.
- Only for rack panel mounting.
- Fuse must be F type and limit value doesn’t exceed 1A.
- No responsibility is assured by manufacturer or any of its subsidiaries
for any consequences arising out of the use of this material.
