3-2 RELAY PANEL, EXPANSION/CONTROL
CABINET
The Relay Panel and Expansion / Control
Cabinet use the same Relay Termination
Board for low-voltage (dry-contact) device
termination.
A Relay Panel is used to control loads
down-line from a breaker panel not
equipped with controllable breakers. A
Relay Panel is shipped from the factory
with the low-voltage side of the relays
terminated to the Relay Termination Board.
Personnel installing the Relay Panel are
responsible for providing and terminating
wires to load side of the relays. Maximum
wire size accepted by the relay terminals is
#10AWG.
An Expansion / Control Cabinet is installed
externally to a breaker panel. The person-
nel installing the above mentioned devices
are responsible for providing termination of
the power supply, network, and all external
low-voltage devices. For power supply
termination, please refer to SECTION 2
Subsection 2-2. For network termination,
please refer to SECTION 5.
Use bottom of the previously described
enclosure types to attach conduit and
provide access to the low-voltage
termination area.
Panels using Expansion Cabinet might or
might not contain 5X-Controller Chassis. For
panels with a 5X-Controller Chassis, the
Expansion Cabinet is used for Application
Specific Controllers only. Only low-voltage
devices and network are terminated in the
Expansion Cabinet. For panels not
containing the 5X-Controller Chassis the
additional step of terminating the remote
controlled breakers to the Control Cabinet
Relay Termination Board is required. For
remote controlled breaker termination,
please refer to SECTION 3 Subsection 3-3.
All low-voltage devices should be termi-
nated on the Relay Panel, Expansion /
Control Cabinet board terminal blocks TB3,
TB4, and TB5. Terminal blocks
TB3
and
TB5
are designated locations for inputs from
low-voltage devices—numbered respec-
tively
1-24
and
25-48
. Terminal block
TB4
is
a
COMMON
(ground) terminal for all low-
voltage devices terminated in the panel.
