This document outlines how to replace a Basic Front Panel on a GE Universal Relay (UR) with an Enhanced or
Graphical Front Panel.

Introduction
A UR can be fitted with one of three types of front panels: Basic, Enhanced, or Graphical. The Basic Front Panel can be
vertical or horizontal. The Enhanced Front Panel has two versions, one that shuts with a finger-tightened knob and the
other with a screw. The latter is referred to as Rev. 2, or the IP54 Front Panel, because it can meet an IP54 enclosure
rating using a mounting collar. Rev. 2 also uses internal hinge screws similar to the Graphical Front Panel. The front
panel is purchased with a UR, or it can be purchased separately and retrofitted. This document outlines how to
replace a horizontal Basic Front Panel with an Enhanced or Graphical Front Panel.

Figure 3: Graphical Front Panel

When purchased separately, a kit includes a front panel and mounting brackets.
The Graphical Front Panel requires CPU module type W or module type T, U, or V (newer type that has two connector
slots on the front of the module). The CPU module can be purchased separately if required.
The steps are as follows:
• Remove the Basic Front Panel
• Install the new front panel
• Replace CPU module for a Graphical Front Panel, if required
• Connect the UR
• Update the UR

Remove front panel

Ensure that power to the UR device and front panel has been disconnected, else death or
WARNING serious injury can result.

To remove a Basic Front Panel from a UR:

1. When installing a new Graphical Front Panel, in the EnerVista software or on the Basic Front Panel, access

 Settings > Product Setup > Communications > Network and record the IP address and subnet mask of the
port(s) being used. Record the gateway address under Default IPv4 Route.
2. Turn off and disconnect power to the unit. Hot-swapping of the front panel is not supported.
3. Lift the latch on the right side of the Basic Front Panel, and open the panel.
Figure 4: Open front panel

4. Disconnect the CPU connector cable and the grounding wire. The figure shows a front panel (left) connected to a
UR chassis (right). The CPU cable is the black RJ45 cable at the bottom. The CPU module is in the second slot of the
UR, labeled slot D. The grounding wire is the flat grey ribbon cable at the top-left.

5. Remove the front panel by lifting it up.

6. Unscrew the screws four full turns on the right and left sides. Do not remove the screws.

The front panel has been removed.

Install new front panel
The installation example here uses Rev. 2 and the Graphical Front Panel.

Ensure that power to the UR device and front panel has been disconnected, else death or
WARNING serious injury can result.

Figure 9: Kit with Enhanced Front Panel (Rev. 2)

To install an Enhanced or Graphical Front Panel on a UR chassis:

1. Slide in the right bracket (1001-0195) and screw it in. The next figure shows the right bracket with an “R.”
Figure 10: Brackets

2. Slide in the hinge bracket (1001-0196) on the left side, and screw it in. The figure shows the left bracket with an
“L.”
3. Knock out the front and bottom tabs from the new front panel. The figure shows needle-nose pliers being used.
Optionally use a nail file to smooth any rough edge.

4. Install the new front panel on the four hinge screws on the left side, using the four hex nuts with tooth washers
(1421-0010).
Figure 13: Install front panel (three hex nuts and tooth washers installed)

The front panel is installed but not connected.

Replace CPU module

The Graphical Front Panel requires a CPU module inside the UR chassis of type W or module type T, U, or V (newer type
that has two connector slots on the front of the module). A CPU module can be purchased with a UR, or it can be
purchased separately and retrofitted.

Withdraw or insert a module only when control power has been removed from the unit,
WARNING and be sure to insert only the correct module type into a slot, else personal injury, damage
to the unit or connected equipment, or undesired operation can result.

 To avoid damage to the equipment, use proper electrostatic discharge protection (for example,
NOTICE a static strap) when coming in contact with modules while the relay is energized.

1. With power to the unit off, at the back of the CPU module in the second slot, note which port has the silver SFP
connector(s), and disconnect any cables. Remove the SFP connector(s), and keep it handy. Then at the front of the
relay, remove the CPU module by lifting the latches and sliding the module out from slot D.
Figure 14: Remove silver SFP connector (shown here under LK1 label)

2. At the front of the relay, insert the new CPU module in the second slot, which is slot D, and close the latches. The
CPU module partly is installed and not connected.

3. At the back of the CPU module, attach the new black cover plate to the back of the relay, then connect the new
RS485 connector.
4. Insert the silver SFP connector(s) at the back of the CPU module, then connect any Ethernet connection(s).
The CPU module is installed but not connected at the front.

Connect the UR
1. For an Enhanced Front Panel, connect the CPU cable from the front panel to the CPU module in slot D of the
chassis. See Figure 5.
For a Graphical Front Panel, as shown in the next figure, connect the CPU cable from the front panel to the upper
slot in the CPU module in slot D. This black connector slot in the CPU module is difficult to see.
Figure 16: Connect Graphical Front Panel to CPU module

2. Connect the grounding wire from the UR chassis to the front panel. See Figure 6. The front panel and UR are now
connected.
3. Close the front panel, screwing it in on the right side.
Figure 17: Close front panel

4. For a Graphical Front Panel, optionally remove the protective plastic film on it. It is normally peeled off, but also
can be left on.
5. For an Enhanced Front Panel, if using a IP54 Mounting Collar Kit, install it. The front panel now has an IP54 rating.
6. Connect the UR to power. If the Graphical Front Panel does not power up immediately, disconnect power, open
the front panel, then check that the front panel is plugged into the upper connection, not the lower silver
connection on the CPU module.
The CPU module and front panel are installed.

Update software
For an Enhanced Front Panel, perform a settings update to recognize the new front panel, as outlined.
For a Graphical Front Panel, upgrade software and firmware, then perform a settings update to recognize the new
front panel, as outlined.
To update the settings for an Enhanced Front Panel:
1. In the EnerVista software, click the Device Setup button and refresh the order code for the device.
2. Set the relay to Programmed mode under Settings > Product Setup > Installation.
To upgrade software and firmware for a Graphical Front Panel:
1. Upgrade the EnerVista software as outlined in a UR instruction manual.
2. Input the IP address and subnet mask of the relay on the front panel under Settings > Product Setup >
Communications > Network, and input the gateway address under Default IPv4 Route.
3. Upgrade the firmware in the EnerVista software as outlined in a UR instruction manual, for example under
Maintenance > Update Firmware.
If you see error messages after the upgrade, disconnect power to the relay and shut down the software, then
start both again. If you see a flashing message about front panel communications trouble, check the connection
of the Graphical Front Panel to the CPU module.
4. In the EnerVista software, click the Device Setup button and refresh the order code for the device.
5. Set the relay to Programmed mode under Settings > Product Setup > Installation.
6. Update the EnerVista software to recognize the Graphical Front Panel under Maintenance > Change Front Panel.
This setting does not display for units that already have a Graphical Front Panel.
If an equipment mismatch error displays on the front panel, it can mean that the order code on the device needs to be
refreshed to the new front panel using the Device Setup button.
Installation is complete.
