1.1.Caution & Warning
The meter contains hazardous voltages, and should
never be disassembled. Failing to follow this practice will
result in serious injury or death. Any work on or near energized meters,
meter sockets, or other metering equipment could induce a danger of
electrical shock. It is strongly recommended that all work should be
performed only by qualified industrial electricians and metering
specialist. ICP DAS assumes no responsibility if your electrical installer
does not follow the appropriate national and local electrical codes.
ICP DAS assumes no liability for any damage resulting from the use of
this product. ICP DAS reserves the right to change this manual at any
time without notice.

2. Installation
2.1.
Products come with external split type clip-on CT’s. Disconnect the
CT’s or use other CT’s is highly prohibited.
Please read this operation manual carefully before using.
Please re-confirm the measure position.
Reconfirm the RST (ABC) phase sequence of the power system.
Meter auxiliary power for PM-3133 series is DC +12V ~+48V.

2.2.Voltage Input
1. PM-3133 series: Input Voltage up to 500V.
For any higher Input Voltage large than 500V, please add the PT
(power transformer), and Change PT RATIO setup.
2. Confirm the RST (ABC) phase sequence.
2.3. Connection
Please firstly check the current input terminal, and then in white
black, white black, white black wire sequences (CT1-P1, CT1-P2,
CT2-P1, CT2-P2, CT3-P1, CT3-P2). Then connect the CT’s, and
close the CT clip. Make sure the arrow direction sign on CT’s
follows current flow direction（P1→P2）.

2.4.Positional Accuracy
1. -500P: W Accuracy Better than 2% (PF=1; Input Current >50A; the “A” area).
-1000P: W Accuracy Better than 2% (PF=1; Input Current >50A; the “A” area).
-2000P: W Accuracy Better than 2% (PF=1; Input Current >50A; the “A” area).
-4000P: W Accuracy Better than 2% (PF=1; Input Current >50A; the “A” area).
2. Due to small variations in the winding density and coil cross-sectional area the
transducer output varies slightly depending on the position of the current within
the coil loop.
The diagram below shows the variation of accuracy throughout
the coil. The variation is greatest when the current is positioned
near the junction of the connecting cable and the coil, where
there is some discontinuity, and the error here can be typically
5%. Since in most applications the current is distributed
throughout a significant part of the area contained by the coil loop
the reading will be very close to the calibration value.

The current should not be positioned close to the
coil-cable junction (shown by the “D” area) since the
error for this region is greater.

3. Communication
3.1.RS-485 & CAN setting
Default setting for RS-485: 19200, n, 8, 1 ,for CAN:125K bps
DIP switch (SW1-SW6) is used for Modbus address(or
CANopen Node ID) setting, default is 1, i.e. all OFF
For example: Modbus address(or CANopen Node ID) is 10，
find the table of DIP switch 1-6 is ON, OFF, OFF, ON, OFF, OFF

For recovering to default settings, dip
Init/Run Switch (SW 4) to Init position for
10 seconds after power on, the settings
will be changed as default values. Must dip
back to Run position and repower on after settings changed. User also can
recover settings to default value by Modbus command.
