General Information
The ControlKeeper T enclosure is available in three different sizes: 16 size, 32 size and 48 size. It can be configured with different relay types as needed to achieve your lighting needs.
Getting Started
1. Do not discard these installation instructions. Please keep for future reference and operation information.
2. The relays and center rail are protected by shrink­wrap. Leave shrink-wrap in place until all drilling and metal work is complete to protect against metal shards getting into component circuitry.
3. Always disconnect all power before wiring.
4. Use only as intended and at the listed voltage.
5. All installation service must be performed by qualified personnel or service technicians.
6. Install in accordance with National Electrical Code and any other codes that may apply.
7. High voltage is present inside the lighting enclosure. Use extreme caution when performing maintenance on this equipment. Failure to follow this warning and proper safety procedures could result in severe injury or death and/or damage to the equipment.
8. Document all wiring that is terminated to the relays so that the lighting control equipment can be properly configured and programmed for operation.
Mounting the Enclosure
1. If the enclosure is a 32 or 48 size, remove the upper backplate from the enclosure by using the 1/4 turn screws provided. The proper operation of these screws is to push in gently and turn 1/4 turn left until the screw head is horizontal to release the catch mechanism. Turning these screws more than 1/4 turn may cause them to break.
2. Choose a dry location convenient to the circuit breaker panel.
3. Mount the panel on a firm surface using pre-drilled holes.
4. Connect the enclosure to the circuit breaker panel using conduit. The conduit punch hole can not exceed 3 inches from the back of the enclosure. If this measurement is exceeded, the logic board will not fit properly inside the enclosure.
5. Remove all cuttings and dirt before removing shrink­wrap from the relays and center rails.
ote:N Make certain that high voltage and low voltage
wiring enters the enclosure separately. High voltage wiring should not be brought into the enclosure through the bottom or bottom left corner of the enclosure.
Low voltage wiring can be brought into the enclosure from the bottom or bottom left of the enclosure. If low voltage wire must be brought into the cabinet from the top section, there is a knockout reserved on the left side which will allow conduit to be run from the top of the enclosure into the low voltage wiring area. Failure to separate high voltage from low voltage wiring may cause interference with logic board function.

Applying Power
1. Once the wiring is complete, make certain that the enclosure is clean of any wire clippings and that no fragments are lodged in the relay circuit boards.
2. Ensure that there are no loose wires or exposed wires that could short.
3. Power-up the unit from the circuit breaker.
4. Once power is applied to the unit, the power LED on the RSC (right next to the override switch) should light up and stay ON. The status LED on the RSC should flash. The Status LEDs on each relay card should also flash indicating that the relay card microprocessor is operating.
5. At this point, lighting loads may be operated via the individual relay override switches on the relay cards or by using the Relay Stack Controller Override Switch.
6. If the enclosure is a 32 or 48 size enclosure, make sure that the upper backplate is in place. To mount the upper backplate, ensure that the 1/4 turn screws are all vertically aligned before trying to place them in place. Starting with the upper left corner, gently press the 1/4 turn screw into its mounting hole. Press all 1/4 turn screws in place in a clockwise method. Once all screws are in place, press down on each screw in turn and gently turn the 1/4 turn screw to the right until the screw head is horizontally aligned. This will lock it in place. Turning the screw further than 1/4 turn may result in it breaking.
Manually Controlling Relays
The relays in the ControlKeeper T enclosure may be controlled before the logic board is in place using the Relay Stack Controller or the individual relay override switches on each relay.
Relay Stack Controller
The Relay Stack Controller (RSC) is at the bottom of the enclosure. It acts as a master override to the system. The RSC contains a three position rocker switch: ALL OFF, AUTO, ALL ON. By moving the rocker switch to the right, the Green LED will be lit and the relays will close. By moving the rocker switch to the left, the Red LED will be lit and the relays will open. The middle, AUTO, position allows the relays to be controlled by the individual relay switches or from the logic controller.
RSC Override Switch
ALL OFF/AUTO/ALL ON
RSC Override Switch
Individual Relay Override Switch
Each individual relay has its own individual relay override switch that may be used as a temporary override to panel programming. If used, that relay will be in the commanded overridden state until the next command from the ControlKeeper T to that relay. The RSC three position rocker switch will be able to override the individual relay override switches. However, when the RSC is moved back to AUTO, it will revert control back to the logic panel or individual relay override switches.
All relay cards have a small round button next to each relay on the board. This button will allow the relay to be overridden ON or OFF. To override the relay ON, press the button until the LED next to the relay lights up. This indicates that the relay has been commanded to close. To override the relay OFF, press the button until the LED next to the relay turns OFF. This indicates that the relay has been commanded to open.

Low Voltage Wiring Notes
Network Wiring Notes
The ControlKeeper T is designed to communicate with other ControlKeeper network panels using a lighting control RS-485 network for communications. This allows the panels to share information and to be programmed from one central location by a computer with the Keeper Enterprise Software.
For best network performance, Belden 9841 cable should be used. If the specified cable is not used and communications problems occur that require troubleshooting assistance, additional charges for support may be assessed.
1. All low voltage wiring is Class 2.
2. All low voltage wiring must enter the cabinet from the lower-left side of the enclosure or be piped through the high voltage section in conduit using the special knockouts reserved for this section.
3. All low voltage wiring must be run in separate conduit from line voltage wiring.
4. Test all network wiring for shorts to AC ground before connecting to the ControlKeeper T panel.
5. Leave all shields disconnected making certain that shield is not exposed.
6. Panels and devices on the RS-485 lighting network should be daisy-chained. Do not create a Star or T-tapped configuration.

GDS Switch Wiring
Each ControlKeeper T unit is capable of supporting the Greengate Digital Switch (GDS) station. The GDS does not wire directly to the ControlKeeper T logic board, but is wired using a CAN Bus network that connects to the ControlKeeper T through a gateway called the GDS-I. GDS stations are wired using the Eaton’s Cooper LCCP or LCCNP cable, or Belden 1502P or 1502R equivallents.
See the ControlKeeper T logic board installation instructions for further details on the connection. All connections to the ControlKeeper T from these devices should be made through the low voltage section of the controller.
For best network performance, one of the suggested cables should be used. If the specified cable is not used and communications problems occur that require troubleshooting assistance, additional charges for support may be assessed.
Logic Board Grounding Strap
The enclosure has a grounding strap located in the left corner of the enclosure which should be connected to the grounding strap provided on the ControlKeeper T logic panel. Please refer to the ControlKeeper T instructions for further information regarding this grounding strap.
