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.

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 conﬁned 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 relay’s SPST output

terminals, and from there to the loads.

Conﬁrm that each circuit is wired to the

relay speciﬁed in the drawings. Wire the

power supply as shown to the left.

This interior is intended for field

installation within the enclosure of

another product.

Refer to installation instructions

INHTUB and INHCVR for installation

of The Watt Stopper

Tubs and Covers.

The following instructions assume

that a UL listed enclosure has been

properly installed.

CAUTION: Make sure all power is off

before wiring. Do not energize wiring

until the unit is fully assembled.

Conform to all applicable codes.

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 conﬁgurations.

Power Up and Test Relays

Apply power to the power supply only.

Press the Relay Control Button next to

each relay’s 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.

Conﬁrm 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 conﬁrm

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 rectiﬁed 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 deﬁne

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 deﬁne 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 conﬁguration

shown below and wire the timeclock to

the OFF (black) input only, or use a

timeclock with pulse outputs.

3-Wire Configuration (C-form contacts)

When wired as shown in Figure 9, closing

the red contact will turn the connected

channels on; the black contact off.

For multiple OFF sweeps, connect to the

OFF contacts only. Automatic ON with

multiple OFF sweeps requires two

separate control outputs on the timeclock

or building automation system.

The timeclock or BAS control module

may be mounted to an optional accessory

bracket, HBRK12SC or HBRKXXSC

(must be ordered separately). 24 volt AC,

40VA accessory power is provided on the

motherboard.
