LiteKeeper® installation. For programming information,
refer to the LiteKeeper® Programming Manual.

Getting Started

1. Do not discard these installation instructions. Please
keep for future reference and operation information.

2. The relay cards are protected by shrink-wrap. 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.

9. It is recommended that all low voltage wiring be
done with power removed to the logic board to
protect components from potential shorts during the
wiring process.

Mounting in the Enclosure

1. Choose a dry location convenient to the circuit
breaker panel.

2. Mount the panel on a firm surface using pre-drilled
holes.

3. Connect the enclosure to the circuit breaker panel
using conduit into the punch holes provided.

4. Remove all cuttings and dirt before removing

Two Pole Relay Card Notes

The Two Pole Relay Card(s) is installed at the factory in the
Lighting Controller specified.

The Two Pole Relay Card relays are shipped separately and
are installed in the field. The relays that are available are
Two Pole Relays rated at 120V/208V or 277V/480V. A Single
Pole Relay is also available, rated at 347V. All relays are
rated to 20 Amps. The following information describes the
installation of the relays onto the Two Pole Relay Card.

Each Two Pole Relay Card has eight mounting clips for the
placement of the relays. The Two Pole Relay Card will hold
eight 208V two pole relays, one in each mounting clip. The
480V Two Pole Relay Card uses two mounting clips, thus
only four relays will fit per card. The Two Pole Relay Card
will hold eight 347 Single Pole Relays, one in each mounting
clip.

1. Position the relay so that the input coil faces the center
of the Two Pole Relay Card and the output contacts
face outwards toward the enclosure walls.

2. Place the input coil side in first then press down with
an even motion and snap the relay into place. (To
remove the relay, press down on the metal release bar
and pull the relay out).

3. The coil control wires (blue and red) and a connector
are supplied already attached to the relay. Simply plug
this connector into the Two Pole Relay Card. The relay
number slot that this connector is plugged into will
be the relay that will need to be programmed in the
controller for proper function. Wire as indicated in the
diagram following.

Connecting Low Voltage Inputs

Connecting Low Voltage Inputs

The LiteKeeper 8® logic board can support up to 64 switch
inputs. Of these 64 inputs, 8 of them may be dry contact
closure inputs that are connected to the terminal blocks on
the left side of the LiteKeeper® Logic Board. Digital switch
inputs may also be used on the LiteKeeper®. If no contact
input type switches are being used, the full 64 switch inputs
may consist of digital switches. If a combination of contact
input switches and digital switches are being used, the
combined total cannot exceed 64 inputs.

Regardless of input type used, it is recommended that all
input wiring be done prior to applying power to the logic
board. Please verify that there are no shorts to AC Ground
prior to connection of input devices.

Regardless of input type, the following notes apply.

1. All low voltage wiring is Class 2 wiring.

2. All low voltage wiring must enter the cabinet into the
low voltage section of the enclosure. Low Voltage
wiring can be brought into the enclosure from the left
side of the enclosure. Failure to separate high voltage
from low voltage wiring may cause interference with
logic board function.

3. All low voltage wiring must be run in separate conduit
from line-voltage wiring.

4. Test all low voltage wiring for shorts to AC ground
before connection to the relay panel.

5. When powering peripheral devices such as motion
sensors and photocells from the LiteKeeper® panel,
there may be a limitation on the number of sensors that
can be supported. This is also true if digital switches
are used with the system. See the recommendations
below or contact Eaton’s Cooper Controls Business for
further information.

6. It is recommended that power be removed from the
logic board when doing initial switch input wiring.

Contact Input Switch Wiring

This section describes the wiring for dry contact closure
devices. There are eight switch input wiring terminals on the
left side of the LiteKeeper-8® to allow for wiring of the dry
contact closure devices.

1. Use 18AWG twisted, unshielded wire for all low voltage
dry contact closure device wiring.

2. Maximum length for dry contact closure device wiring
is 1000 feet.

LiteKeeper® 8

Digital Switch Wiring

Digital Switch Wiring

Each LiteKeeper 8® unit is capable of supporting the
Greengate Digital Switch (GDS) station. The GDS do not
wire directly to the LiteKeeper 8® logic board, but are wired
using a CAN Bus network that connects to the LiteKeeper
8® through a gateway called the GDS-I. GDS stations are
wired using the Eaton’s Cooper Controls LCCP or LCCNP
cable, or Belden 1502P or 1502R equivallents.

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.

Digital Switch devices should be networked together in a
daisy chain configuration. No T-Taps/Stars should be used.
The GDS-I device should reside somewhere within the
daisy chain switch network. Total daisy chain network length
should not exceed 1000 feet.

The following instructions describe the GDS-I device
connection to the LiteKeeper 8®. Please refer to the
Greengate Digital Switch installation instructions for
information on wiring the Digital Switch Network to the
Digital Switch Gateway.

1. Mount the GDS-I next to the LiteKeeper®-8 panel.
A six foot phone style cable has been provided for
connection to the LiteKeeper-8® panel.

2. Run a length of the Digital Switch LC or Belden cabling
from the GDS-I location to the low voltage section of
the LiteKeeper 8®.

3. Connect the RED wire in the cable to the +V terminal
on the back of the GDS-I and to the LiteKeeper 8® at
one of the switch input +24 VDC terminals.

4. Connect the BLACK wire in the cable to the GND
terminal on the back of the GDS-I and to the LiteKeeper
8® remote power connector GND terminal.

5. Tape back or cap the blue and white wires and shield
wire for the cable. They will not be used for connection
between the GDS-I and lighting controller.

6. Locate the 6 foot phone style cable included in the
GDS-I box. Run this from the GDS-I into the low voltage
section of the LiteKeeper 8® enclosure plugging the
end with 9 pin head into the GDS-I. Plug the end the
RJ11 phone style plug into the LiteKeeper 8®.

7. It is recommended that power be removed from the
logic board when doing initial switch input wiring.

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 to other wires or components.

3. Power-up the unit from the circuit breaker.

4. Once power is applied to the unit, lighting loads may be
operated via the ALL ON/ AUTO/ ALL OFF switch
as necessary.

Manually Controlling Relays

The relays in the enclosure may be controlled before the
logic board is programmed by using the on-board, ALL OFF,
AUTO, ALL ON switch. In the ALL ON position the relay
coils will be energized. In the ALL OFF position, the relay
coils will be de-energized. The middle, AUTO, position allows
the relays to be controlled by the individual relay switches or
from the logic controller.
