Connecting Relay Loads
1.
Test branch circuits for short circuits prior to connecting
and energizing the ControlKeeper 4.
2.
Relay terminal blocks have a maximum limit of 10 AWG
wire.
3.
Relays are rated for single-pole circuit use. Connection
of 2 pole circuits/loads to the ControlKeeper 4 will void
the equipment warranty.
4.
Connect a 120 or 277 volt, 20 amp maximum,
de-energized branch circuit breaker to the relay terminal
block position labeled LINE.
5.
Connect the load to the output terminal block position
labeled LOAD.
6.
Tighten down relay terminal screws. Manufacturer's
recommended torque rating is 7 lbs-in. (0.59 lbs-foot)
(0.8Nm).

Network Wiring Notes
The ControlKeeper 4 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.
Please refer to Table 1 for information on recommended
wiring for network.

Table 1. Network Wiring Recommendations
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.
1.
All low voltage wiring is Class 2.
2.
All low voltage wiring must enter the cabinet from the
left side of the enclosure.
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 4 panel.
5.
If using Belden 9841 or 89841, 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.
7 .
Total network length should not exceed 4000 feet.
Network Wiring Details
1.
Before wiring, select the two panels that are going to
be the end panels of the network and plan a wiring
scheme accordingly. Panels should be daisy-chained,
not Star or T-Tapped.
2.
Starting at one of the end panels, connect the network
(+) and (-) terminals to the next panel's network (+) and
(-) terminals. Continue this process through the network
