Installation
Instructions
1. Using appropriate hardware, mount PDU to rack (see Mounting section for additional
instructions.
2. Connect PDU into de-energized appropriately rated branch circuit with plug or hardwired
connection depending on PDU design1.
3. Connect devices into PDU’s output receptacles. It is recommended that the devices are
turned off until all devices are connected to PDU
4. Turn on branch circuit to energize PDU.
5. Power on devices. Sequential power up is recommended to avoid high inrush current.
Guidelines
•If the PDU is installed in a cabinet the ambient temperature of the rack should be no greater
than 45°C.
•Install the PDU such that the amount of airflow required for safe operation of equipment is
not compromised.
•Mount the PDU so that a hazardous condition is not achieved due to uneven mechanical
loading.
•Follow nameplate ratings when connecting equipment to the branch circuit. Take into
consideration the effect that overloading of the circuits might have on over-current
protection and supply wiring.
•The PDU relies on the building installation for protection from over-current conditions. A
certified overcurrent protection device is required in the building installation. The
overcurrent protection device should be sized according to the PDU’s nameplate ratings and
local/national electrical codes.
•Reliable earthing of rack-mount equipment should be maintained. Particular attention
should be given to supply connections other than direct connections to the branch circuit.
The PDU must be connected to an earthed socket-outlet.
•The PDU is intended for Restricted Access Locations only and only qualified service
personnel should install and access the PDU.
•For pluggable equipment, install the PDU so that the input plug or appliance coupler may be
disconnected for service.
•Sequential power-up of devices powered by the PDU is recommended to avoid high inrush
current.
•Caution: Disconnect all power cords before servicing.
•The PDU is intended for use with TN, TT, or IT power supply systems
1Branch Circuit overcurrent protection should be sized based on the PDU’s nameplate electrical
rating. For cord connected North American units the branch circuit overcurrent protection should
be rated 125% of the nameplate current rating. For cord connected Global units and all
permanently connected units the branch circuit overcurrent protection should be rated for 100% of
the nameplate current rating.

LED Display
Each PDU has a built-in 4-digit LED display mounted midway down the chassis. The display
scrolls through the most recent current measurement (in amps) for each circuit, one at a time.
It displays a circuit name, pauses, and then displays the measurement. Momentarily press the
“Pause Scroll/IP Address Reset” button on the front of the PDU to pause the display on the
current measurement. While paused, the display will cycle back and forth between circuit name
and current reading every three seconds. Momentarily pressing the “Pause Scroll/IP Address
Reset” button again will skip ahead to the next circuit. The display will begin to scroll again
thirty seconds after the last button push.
Notes: During the first cycle after the display has been paused, the display may take
up to six seconds to display a measurement.
Due to the time required to measure current accurately, the same reading
may be shown twice while the display is paused.
For reference: Cr-1 = Circuit 1 Ph-A = Phase A
Cr-2 = Circuit 2 Ph-b = Phase B
Cr-3 = Circuit 3 Ph-C = Phase C
Cr-4 = Circuit 4 nEUt = Neutral
Cr-5 = Circuit 5 Fd-A = Feed A
Cr-6 = Circuit 6 Fd-B = Feed B
Viewing the IP Address/Resetting to Default IP
In the event that the IP address of the PDU is lost, it is possible to view the currently configured
IP address on the unit’s built-in LED display or reset the IP address to the default.
To view the IP address, press and hold the “Pause Scroll/IP Address Reset” button on the front
of the PDU for 20 seconds. The screen will stop displaying scrolling power data in order to
display the currently configured IP address. The display will show the IP address using the
following format:
c-IP
Æ aaa Æ . Æ bbb Æ . Æ ccc Æ . Æ ddd
The ‘Æ’ indicates a pause and the aaa/bbb/ccc/ddd indicate a portion of the currently
configured IP address. The IP address will be displayed twice before normal scrolling continues.
CAUTION: If the “Pause Scroll/IP Address Reset” button is being held while the
second segment (bbb above) of the IP address is being displayed, the unit’s IP
address will be reset. To prevent this, release the button as soon as “c-IP” shows up
on the display.
To reset the IP address to the backup IP address, press and hold the “Pause Scroll/IP Address
Reset” button on the front of the PDU for 20 seconds, at which point the display will show the
current IP address. Continue to hold the “Pause Scroll/IP Address Reset” button for 10 more
seconds and the display will switch to scrolling d-IPÆ192Æ.Æ168Æ.Æ123Æ.Æ123. The IP
address is then reset to 192.168.123.123. The display will resume its normal function after the
display shows the IP address twice and the “Pause Scroll/IP Address Reset” has been released.
Once the IP address has been reset, the Setting an IP Address instructions should be followed
to access the unit.

GM1099.doc 19 Revision Date: 1/25/2011
Rebooting the Meter
Should an Current Monitoring Meter with firmware version 1.36 or higher installed stop
responding to network traffic, it is possible to restore functionality by rebooting the meter
without removing power from the PDU it is enclosed in.
To reboot the meter, press and hold the “Pause Scroll/IP Address Reset” button on the front on
the PDU for 20 seconds. The screen will stop displaying scrolling power data in order to display
the currently configured IP address. The display will show the IP address using the following
format:
c-IP
Æ aaa Æ . Æ bbb Æ . Æ ccc Æ . Æ ddd
The ‘Æ’ indicates a pause and the aaa/bbb/ccc/ddd indicate a portion of the currently
configured IP address. As soon as “c-IP” is displayed, release the “Pause Scroll/IP Address
Reset” button. Press and release the “Pause Scroll/IP Address Reset” button twice while the IP
address is being displayed. The screen will read “8.8.8.8.” for a few seconds and then resume
scrolling normally, indicating a successful reboot.
Web Page
The main interface to the PDU is its web page, accessible by typing the unit’s IP address into a
web browser. The web page is the source for the most up to date measurement of each circuit.
All measurements are in Amps.
SNMP/XML
In addition to HTML based web pages, the PDU presents its data via SNMP and an XML page.
To use the PDU with SNMP Client software, download the MIB from the link on the unit’s web
page and import it into the SNMP software. Contact the client software manufacturer for
instructions specific to their software. The PDU’s SNMP community comes preset to ‘public’. To
change this, go to the ‘Configuration’ page, enter a new name in the SNMP Community box and
hit “Save Changes.” In addition SNMP traps can be utilized to monitor a user set threshold for
each circuit, alarm settings and SNMP server settings are located on the ‘Configuration’ page.
The XML page provides terse output that is easily parsed by both humans and computers and is
useful for creating scripts to download and process information off the unit automatically. The
XML page is available at http://<IP address of meter>/data.xml.
Sample uses of XML and SNMP data are provided in the Sample Usage section of this
document.
Firmware Updates/Instructions
The unit firmware is field upgradeable via FTP. Firmware updates and instructions are available
at the following website.
http://www.geistmfg.com/GeistUS/Docs/downloads.htm

Sample Usage
The simplest way to get data from a Current Monitoring Meter into a script is via the XML page.
Simply performing an HTTP GET (as a web browser does) on http://<IP address of
meter>/data.xml will download the XML file. The following examples assume that the meter’s
IP address is 192.168.123.123.
Perl Example:
using LWP::UserAgent;
my $ip = "192.168.123.123";
my $browser = LWP::UserAgent->new;
$browser->timeout(5);
my $xmlFile = $browser->get("http://" . $ip . "/data.xml" )->content;
At this point, $xmlFile will contain the text of data.xml, ready to be parsed however necessary.
Unix/Linux Command Line Example:
wget http://192.168.123.123/data.xml
This command will download data.xml into the current directory. At this point, the file is ready
to be used by any local application or script.
SNMP Example
Getif is a simple, free SNMP viewer for Windows available from:
http://www.wtcs.org/snmp4tpc/getif.htm
1. Drop the EM meter’s MIB file into Getif’s MIBs directory (Typically C:\Program Files\Getif
2.3.1\MIBs) and start Getif.
2. Type in the unit’s IP address into the box labeled “Host Name” and click the Start
button.
