Theory of Operation continued:
Frequency Measurement:
The PL-PM1 measures the frequency of the AC line
voltage from 47 Hz to 63 Hz with an accuracy of 0.1
Hz.
System Reset
:
The PL-PM1 is intended to be tolerant to interference
and EMI. The system has a watchdog timer such that
if measurements stop being displayed, the system
will automatically reset itself and resume
measurement.
PL-PM1 Calibration:
Calibration information is held internally in a non-
volatile memory. This is set at the factory and there is
no provision for field calibration. When powering up, if
for any reason calibration information is lost, the
system will display “EEP Err” in the display. The
meter will still function except that the accuracy will
be reduced to 5%.
Equipment Ratings:
Supply Voltage Range: 108-229 VAC
Power draw: 10 Watts maximum
Frequency Range: 40 to 100 Hz
Environmental Conditions:
Ÿ
Indoor Use
Ÿ
Altitude up to 2000 meters
Ÿ
Temp range 5° C to 40° C
Ÿ
Maximum relative humidity 80% for temperatures
up to 31° C decreasing linearly to 50% relative
humidity at 40° C
Ÿ
Mains supply voltage fluctuations up to ±10% of
the nominal voltage
Ÿ
Overvoltage Category III; Distribution level, fixed
installation
Ÿ
Pollution Degree 2
Equipment Installation:
Connections to the PL-PM1 are made through pluggable Wago Eurostyle connectors. The voltage sensing input is a
5 pin connector with the Earth contact mating first and the current sensing input is an eight pin connector. The
connectors are prewired to harnessing for connection to the system AC input terminals and the current sensing
coils. Maximum working voltage is 229 VAC and the PL-PM1 is rated at measurement category III.
Ÿ
Confirm that all power is disconnected from the system.
Ÿ
Disconnect device is considered a circuit breaker that is part of facility wiring per NEC.
Ÿ
Install a current coil around each hot leg wire and the neutral wire.
Ÿ
Connect the four pair current coil wiring harness to the coils following the labels on the wire pairs. It is
recommended to connect the red and black in a consistent fashion on all the coils.
Ÿ
Connect the 5 conductor voltage wiring harness to the incoming line connectors following the color code;
green is protective earth ground, white is neutral, black, red and blue are the hot legs.
Ÿ
Connect a Protective Earth (Ground) wire from the #10-32 stud on the rear of the chassis to the Green
Protective Earth (Ground) input connection.
Ÿ
Connect the Wago 5 pin and 8 pin Voltage and Current connectors to the PL-PM1.
Ÿ
Securely attach the PL-PM1 to the rack rails of the enclosure.

WHIRLWIND PL-PM1RJ ETHERNET CONNECTIVITY INFORMATION
The following information applies only to the PL-PM1RJ Power Meter.
The PL-PM1RJ model has Ethernet connectivity for network monitoring of power distribution parameters in real time.
The PL-PM1RJ provides monitoring from any location or multiple locations simultaneously by accessing the
Ethernet LAN that the meter is connected to. The PL-PM1RJ has an assignable IP address that can be set to fit into
your current network. If multiple units are on the same network, each can be assigned its own unique IP address and
name. Each meter is viewed through a separate web browser window. Use Internet Explorer 11 or greater and Apple
Safari for best viewing.
PL-PM1RJ Power Meter Network Setup
To view the PL-PM1RJ Power Meter in a web browser, the browser will need to know the IP address of the Power
Meter. Browser cookies must be enabled to properly view the meter parameters. It is possible that the default
address will work, unchanged, on your existing network. Assuming that the address is not compatible with your
existing network, the following explains how to access the Power Meter and how to change its IP address to be
compatible with your network.
Default Address
The PL-PM1RJ is shipped from the factory with a
static IP address of 192.168.1.200 and a subnet
mask of 255.255.255.0. At any time, the IP
address stored in the Power Meter can be viewed
by pressing the mode button in for more than 3
seconds. The IP address will appear in the top
row of LED number displays and the subnet mask
will appear in the lower row of numbers. Press
the mode button again to exit this mode.
If you use the PL-PM1RJ on a small network, and
the network router is set at 192.168.1.1 with a net
mask of 255.255.255.0 (a common default
address for small networks), and as long as the
address of 192.168.1.200 is not already in use, no
changes to the IP address will be needed. Simply
plug the unit into your network's router or switch,
then with a computer that is also on the same
network, use a browser and type in the URL for
the Power Meter which will be:
http://192.168.1.200/.
The display you see should look like the following,
however the IP address will be different than shown.
Once your browser finds the Power Meter, it will
be redirected to a sub directory in the meter and
you will see http://192.168.1.200/plpm1rj.html in
the address bar of the browser window. If this
address is acceptable, then no further work is
needed.
