6. Test all low voltage wiring for shorts to AC ground
before connection to the ControlKeeper T panel.
Low Voltage Analog Input Wiring
This section describes the wiring for analog input devices.
1. All low voltage wiring is Class 2 wiring.
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. Use 18 AWG twisted, unshielded wire for all low
voltage analog device wiring.
5. Maximum length for analog device wiring is 500 feet.
6. Test all low voltage wiring for shorts to AC ground
before connection to the ControlKeeper T panel.
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.

UL 924 Compliance
With the addition of the Relay Interface Module accessory,
the lighting control system has been approved in
compliance with UL 924. If using the Relay Interface
Module, it will be necessary to wire the transformer to
an emergency power source. Please refer to the Relay
Interface Module’s installation instructions for further
details.
