Compliance Statement (Part 15.19)

This device complies with Part 15 of the FCC Rules.
Operation is subject to the following two conditions:

1. This device may not cause harmful interference, and

2. This device must accept any interference received,
including interference that may cause undesired operati o n.

Warning (Part 15.21)

Changes or modifications not expressly approved by the party
responsible for compliance could void the user’s authority to
operate the equipment.

FCC Interference Statement (Part 15.105 (b))

This equipment has been tested and found to comply with the
limits for a Class B digital device, pursuant to Part 15 of the FCC
Rules. These limits are designed to provide reason able protection
against harmful interference in a residential installation. This
equipment generates uses and can radiate radio frequency
energy and, if not installed and used in accordance with the
instructions, may cause harmful interference to radio
communications. However, there is no guarantee that
interference will not occur in a particular installation. If this
equipment does cause harmful interference to radio or tel evision
reception, which can be determined by turning the equipment
off and on, the user is encouraged to try to correct the
interference by one of the following measures:

- Reorient or relocate the receiving antenna.

- Increase the separation between the equipment a nd receiver.

- Connect the equipment into an outlet on a circuit different
from that
to which the receiver is connected .

- Consult the dealer or an experienced radio/TV technician for
help.

DESCRIPTION

The 2WT-2RA-R6 is a radio transceiver module. These modules are used to make a
system consisting of a master device and slave devices. Each slave device also contains
two (2) electromechanical relays on it. Refer to TECHNICAL DATA for relay rating.
The master device will control the slave device(s) and can send an “on” or “off” signal to
each slave device. The slave device will then open the relays for a received “off” signal
or close the relays for a received “on” signal. The relays on the slave modules are
normally closed (NC).

INSTALLATION

AC power supply connection:
Warning: Turn power off before you connect this device to your power supply.
Make sure your power supply voltage matches the receiver power supply
requirements: 120 VAC or 277 VAC.

Attach the power cable to the female Mate N Loc connector located in the housing of the
2WT-2RA-6A unit.

Load Connection:
Warning: Make sure the power supply voltage matches the voltage of the load to be
controlled. Otherwise fire or damage to the device or load may occur and it may
cause electrical shock.

A male Mate N Loc connector is located at the end of the cable protruding from the
2WT-2RA-R6 housing which plugs into the load to be controlled.
Warning: Make sure the load to be connected does not exceed the relay rating. Otherwise
fire or damage to the device may occur. Please refer to TECHNICAL DATA for relay
rating.

OPERATION
Warning: Make sure your power supply voltage matches the receiver power supply
requirements: 120 VAC or 277 VAC. Otherwise there is electrical shock hazard.

Warning: The load must match the relay rating. Otherwise fire or damage to the receiver
may occur.
After the master and slave devices are properly connected to the power supply and load,
turn the power on. The load attached to the slave device(s) can then be turned on or off
by the 2WT-2RA-R6 master device.
