emu3/emu3ACO Operation Guide 5
Version 2.1
General Description
General Description
The emu3/emu3ACO updates the previous IPE eMu2 PDU range.
The emu3/emu3ACO is a twelve-output power distribution unit with an embedded web server to allow IP control.
The standard model, in intelligent mode, can be set as a Master or Slave; the Automatic Changeover (ACO) model can
failover between redundant supplies.
All units contain an embedded web server, that enables continuous remote control and monitoring via the IPE
Dashboard. They can be daisychained to other emu3 units to provide up to 48 outputs via a single IP connection.
In the event of a Master unit failure, simply move the Ethernet connection to a secondary unit, which then
automatically becomes the new Master.

Installation Instructions
Installation Instructions
This section explains how to install and connect your emu3 system.
Changing the Master emu3 IP address
By default, all emu3 units are congured with an IP address of 192.168.0.209. This address is in the space reserved
for private networks. If you are daisychaining multiple emu3 units in a Master/Slave setup, only the Master unit is
directly connected to your LAN (the Slave units are controlled from the Master’s LINK OUT port).
You will only need to change the default IP address of your Master emu3 unit in the following cases:
• There is already a machine on your network with the IP address 192.168.0.209
• Your LAN uses a dierent IP address space
If neither of the above applies, you can go straight to the next section, “Install the units and make earth connections”
on page 10.
To change the IP address space of your Master unit:
1. Congure a standalone PC (i.e. one not connected to your LAN) with the IP address 192.168.0.1.
2. Connect a CAT5e cable from the standalone PC to the LAN connector on the rear panel of your Master unit.
3. Connect an IEC mains power cable to the MAINS connector on the rear panel.
4. Plug the cable into a wall outlet and switch on.
If you are using an emu3ACO, you only need to connect one power cable, e.g. to the MAINS A connector.
5. Open a web browser on the standalone PC and enter the url 192.168.0.209
The Login web page should be displayed. If it does not, wait a few moments and refresh the web page.
6. Enter the user name and password these are both set to admin by default) and click Login. This will display the
Overview page of the IPE Dashboard.

your LAN.
10. Click OK.
11. Once the unit has rebooted, remove the power and LAN cables.
12. If necessary, recongure your standalone PC to its original IP address settings.
13. Go to the next section, “Install the units and make earth connections”on page 10.

10 emu3/emu3ACO Operation Guide
Version 2.1
Installation Instructions
Install the units and make earth connections
To install the units:
1. If required, slide the units into your 19" rack and secure with standard rack-mount bolts.
2. Make earth connections to all the units.
Make the LAN and LINK connections
The Master unit is the only unit directly connected to your LAN. Slave units do not have a direct network connection
to your LAN, but are controlled from the Master unit’s LINK OUT port.
IMPORTANT!!: Do NOT plug a network cable into a Slave unit’s LAN port if it is already connected to a Master unit.
Note: Master and Slave units can be either emu3 or emu3ACO. In the picture below, we show the Master as an
emu3ACO, connected to two emu3 Slave units.
To make the LAN connection:
1. Connect a CAT5e cable from your network hub to the LAN connector on the rear panel of your Master unit.
2. Connect a CAT5e cable from the LINK OUT connector on the rear panel of the Master unit to the LINK IN
connector on the rst Slave unit in your chain.
3. Connect any additional Slave units using CAT5e cables, going from the LINK OUT connector of the previous unit
to the IN connector of the next unit.

• The opto isolator inputs are NOT polarity dependent. Operating voltage is 5Vdc to 30Vdc (12Vdc nominal).
• The 5Vdc output available on the connector is current limited and is designed to only operate the input opto
isolators.
• The absolute minimum operating voltage is around 3.6V, so driving them from a 5V supply via an open collector
output is not reliable.
• Since the minimum operating voltage is low it is possible that, for a high DC supply (e.g. 15V and above), driving
the opto via an open collector output may cause the opto to not turn o reliably, due to the residual voltage
within the circuit.

12 emu3/emu3ACO Operation Guide
Version 2.1
Installation Instructions
Connect any sensors
You can connect up to four temperature or humidity sensors (available from IPE) to each emu3/emu3ACO unit:
Note: See “read sensor command”on page 31 for details on using Telnet to read sensor values.
1. Connect a sensor to the SENSOR port on the rear panel of an emu3/emu3ACO unit using a standard CAT5e RJ45
cable.
2. Daisychain additional sensors as as required.
Connect mains power
emu3 and emu3ACO units use powerCON locking 3-pole power connectors.
Note: emu3 units do not have dedicated ON/OFF switches. They power up as soon as mains power is applied.
1. Connect IEC mains power cables from the MAINS ports on the rear panels of your emu3 units to suitable mains
outlets.
For emu3ACO units, connect power cables to both MAINS A and MAINS B ports.
2. Connect any devices to be powered by your emu3 system to the mains outlet ports (1-12) on the rear of the
units.
3. Switch on mains power at the wall.
4. Allow a few moments for the units to power up and connect to your LAN.
