External Shunt Modules 7
Install the External Shunt Module
These procedures assume you have prepared your mounting panel and understand how to bond your system components.
Mount the External Shunt Module
Follow these steps to mount your external shunt module.
1. Lay out the position for your shunt module.
Refer to Product Dimensions
, beginning on
page 8
, for mounting hole locations.
IMPORTANT
To improve EMC performance, mount the module on the same panel as the drive and as close to the drive as possible.
2. Attach the shunt module to the cabinet by using M6 (0.25 in.) bolts.
Make sure all fasteners are properly bonded to the subpanel.
3. Tighten all mounting fasteners.

Wire the External Shunt Module
This section assumes you have mounted your external shunt module and are ready to wire the shunt module power connections.
Refer to Additional Resources on page 16 for the specific user manual with drive-end installation
instructions for your servo drive.
IMPORTANT
The National Electrical Code and local electrical codes take precedence over the values and methods provided.
Wire must be copper with 105
°C (221 °F) 600V minimum rating.

Follow these steps to wire your external shunt module.
1. Remove power from your drive system that includes the Bulletin 1394 or 2090 shunt module.
ATTENTION: This system can have multiple sources of power and more than one disconnect switch to de-energize the system. To avoid shock hazard or personal injury, verify that all power has been removed before proceeding.
ATTENTION: This product contains stored energy devices. To avoid hazard of electrical shock, verify that all voltage on the capacitors has been discharged before attempting to service, repair, or remove this unit. Do not attempt the procedures in this document unless you are qualified to do so and familiar with solid-state control equipment and the safety procedures in publication NFPA 70E.
2. Prepare the shunt DC-bus wires for attachment to the shunt power terminals by removing 10 mm (0.39 in.) of insulation.
IMPORTANT
Use caution not to nick, cut, or otherwise damage strands as you remove the insulation.

3. Insert one wire into the shunt power terminal labeled COL.
4. Insert the other wire into the shunt power terminal labeled DC+.
5. Tighten both screw terminals.
Refer to torque values in the table on page 9 .
6. Gently pull on each wire to make sure it does not come out of its terminal; reinsert and tighten any loose wires.

Wire the Shunt Module Fan
This procedure applies to only the 1394-SR36AF shunt module and assumes that you have mounted the module and wired the shunt DC-bus connections.
Refer to Additional Resources on page 16 for the specific user manual with drive-end installation
instructions for your servo drive.
You can wire the shunt fan connections for 115V or 230V AC input power. Wire must be copper with 75
°C (167 °F) minimum rating.

Follow these steps to wire the shunt fan.
1. Verify that all power is removed from the system.
2. Open the front door of the shunt module.
3. Use a screwdriver to remove the plate that covers the fan wire access hole on the bottom right side of the module.
Refer to the figure on page 10 for the location of the fan power terminal block.
4. Insert the jumper wires that came with your shunt module to support the input power used in your application.
5. Insert one wire from the AC power supply into terminal 1.
