HINxxy12SC/24SC/48SC
Smartwired Contactor Panel Interior
Installation and Setup
The HINxxy12SC/24SC/48SC is the interior for a
Smartwired Contactor Lighting Control Panel.
The interior provides isolation between the line- and
low-voltage sections of the panel, as well as the
mounting frame for relays, the power supply and
optional control devices.
A complete panel assembly also includes one each of
the following:
1. Tub (HTUB series)
2. Cover (HCVR series)
3. Power Supply (HPSM115/277)
The Smartwired Contactor provides a simple way to
group lighting circuits by function for both manual and
automatic control. For example, in a store application,
several display, showcase and general-lighting circuits
could be grouped for control by three low-voltage
switches with pilot indication. A fourth switch could
provide master control for all of the lighting and also
tie into the building automation scheduling system.
The HINxxyxxSC has separate channels for grouping
any combination of the relays (lighting circuits) in the
panel. Channel switches within the panel provide
built-in override capability. Two independent inputs per
each allow both remote manual switches and automa-
tion contacts to control that group.
Automation system distributed control modules may
be mounted within the unit to simplify wiring (requires
a separate bracket, HBRK12SC or HBRKXXSC,
which is not provided with the interior).
Before starting, read the instructions that follow. If
you have any questions, call our Service Team at:
888-852-2778.
Retain these instructions and the completed
documentation cards in the plastic sleeve affixed
to the rear of the panel cover. 2

Smartwired Contactor Panel Interior Installation and Setup
ILLUSTRATION NOT TO SCALE
Install Interior
Attach the power supply to the frame
(bottom of 12-relay interior and left side
of 24- or 48-relay interiors) as shown to
the left, and plug the low-voltage
connector to the terminal marked
POWER.
Mount the interior in the tub and secure
it to the studs with the hardware sup-
plied. Make sure that all line- and low-
voltage wiring is conned to the appro-
priate areas.
Wire Line Voltage
Before making any connections to the
relays, make sure that none of the load
circuits are shorted. Wire from the circuit
breaker through each relays SPST output
terminals, and from there to the loads.
Conrm that each circuit is wired to the
relay specied in the drawings. Wire the
power supply as shown to the left.

The following instructions assume
that a UL listed enclosure has been
properly installed.
CAUTION: Make sure all power is off

Wire Low Voltage
Remote low-voltage switches and
isolated contacts (from a timeclock or
building automation system) are wired to
the channel inputs on the panel. Each
channel will accept two inputs, each of
which may be either a 2- or 3-wire
maintained or momentary device as
shown in Figure 2.
The HINxxy12SC interior has 4 channels,
the HINxxy24SC, 8 channels and the
HINxxy48SC, 16 channels. Pages 4 and
5 show common wiring congurations.
Power Up and Test Relays
Apply power to the power supply only.
Press the Relay Control Button next to
each relays yellow plug-in termination to
toggle it on/off as shown in Figure 3.
The relay should click and the LED
status indicator should change state.
Conrm the operation by measuring the
line-voltage terminations of each relay.
Apply power to the relays. Being careful
not to touch any line-voltage wiring,
toggle each relay on/off again and conrm
that each controls the appropriate load.
Relays may be smarwired to the channels
as shown in Figure 4.
Document Wiring
Record the circuit controlled by each
relay on the Smartwired Contactor
Relay Schedule included with these
installation instructions. Also indicate
which relays are controlled by each
channel. Place the Schedule in the
plastic envelope and attach it to the
inside of the panel cover.
1 Press and hold the Channel Push Button for several seconds. The channel LED
and the LEDs for relays currently controlled by that input will begin to flash.
2 Select the relays to be controlled. The LED for each relay smartwired to the
channel input selected will be flashing on/off. Press the associated Relay Control
Button to add/delete that relay to/from the group.
3 Press the Channel Push Button again. The LEDs will stop flashing and the input
switch will now control the relays selected.
Test. Press the Channel Push Button to toggle the group on/off/on. The input
LED will track the last action. Now, turn off each relay in the group using the individual
Relay Control Buttons. When the last relay is turned off, the channel LED should also
go off.

Typical Wiring Diagrams
Remote Manual Switch (3-wire)
Single or multiple remote low-voltage
momentary switches may be wired to a
channel input as shown in Figure 5. For
multiple switches, a separate black/red is
required for each switch, plus a single
white common.
Remote Pilot Light Switch (4-wire)
Each channel has an associated pilot
relay rated at 1 amp. One side of each
pilot relay is connected to a yellow
common, the other to the Y terminal on
the channel terminal strip (see Figure 10).
For typical 24 volt rectied pilot lights,
connect the YEL COM to the 24VR on
the ACC. POWER terminal as shown in
Figure 6.
Master Control of Channels in
Several Panels
Channel inputs in multiple panels may
be wired in parallel as shown in Figure 7,
provided all of the power supplies are
wired to the same phase.
Master Control of Several Channels
within a Panel
While it is permissible to jumper several
switch inputs together to form a master,
the recommended approach is to dene
another channel to include all of the
relays controlled by the individual
channel switches. When this master is
turned on or off, all of the individual
channel switches will track appropriately.

Typical Wiring Diagrams
Automation or Timeclock Control
(Isolated Contacts Only!)
Single-pole, 2-Wire Configuration
Wire as shown in Figure 8.When the
control contacts open, the channel is
turned off; when closed, it is turned on.
You may wire the control contacts to
several channels within a panel. How-
ever, as with Master Switches on the
previous page, it is better to dene a
separate channel to provide the master
function. If multiple panels are controlled,
the power supplies in each must be on
the same phase.
Note: If you are trying to provide multiple
OFF sweeps to catch overrides, you
should use the 3-wire conguration
shown below and wire the timeclock to
the OFF (black) input only, or use a
timeclock with pulse outputs.
