AJAX Relay User Manual

The communication range with the hub in the line of sight is up to 1,000 meters.
Take this into account when choosing the location for Relay.
If the device has a low or unstable signal strength, use the
.
Installation process:
When installing Relay in the box, lead out the antenna and place it under the
plastic frame of the socket. The bigger the distance between the antenna and
metal structures, the lower the risk of interfering (and impairment) of the radio
signal.
Do not shorten the antenna! Its length is optimal for operation within the used radio
frequency range!
During the installation and operation of Relay, follow the general electrical safety
rules and the requirements of electrical safety regulatory acts.
It is strictly forbidden to disassemble the device. Do not use the device with
damaged power cables.
Do not install the relay:
Maintenance
ReX radio signal
range extender
1. De-energize the cable to which Relay will be connected.
2. Connect the grid wire to the Relay terminals according to the following
scheme:
1. Outdoors.
2. In metal wiring boxes and electrical panels.
3. In places with temperature and humidity exceeding the permissible limits.
4. Closer than 1 m to a hub.
