5. Antenna connection*
Ensure the Antenna cable is screwed tightly to the Antenna connector on the top of the MelcoREMOTE unit.
To maintain the appropriate EMC classification for the intended environment the Ferrite Core supplied with
the MelcoREMOTE must be installed onto the antenna cable with 2 loops (Image below), and be located at the
boundary of the panel the MelcoREMOTE is installed within.
The antenna should be located on a metal surface, as the antenna has a magnetic base.
The most suitable location for the antenna can be discovered by checking the antenna signal strength via the display
on the MelcoREMOTE unit.
*Only for GPRS version MelcoREMOTE2G

Page 14 of 52
6. Ethernet connection
If communication via Ethernet is required then in order to maintain the appropriate EMC classification for
the intended environment a cable ferrite (Wurth 74271221S) must be Installed onto the CAT 5/6 cable with 1
loop (Image below), and be located as close as possible to the MelcoREMOTE Ethernet socket.

Page 15 of 52
7. Connecting power
A double pole (Live and Neutral) 5A switch or circuit breaker must be provided in line with the supply to the
MelcoREMOTE power supply and be in close proximity to it. It must be clearly marked as the disconnecting device for
the MelcoREMOTE.
Ensure the mains cable supplying the power to the MelcoREMOTE power supply is suitably rated for the intended
environment and current draw of the MelcoREMOTE.
Warning:
Electrical work should be done by qualified electrical engineers / electrician in accordance with "Engineering
Standards for Electrical Installation" and supplied installation manuals. Dedicated circuits should also be
used. If the power circuit lacks capacity or has an installation failure, it may cause a risk of electric shock or
fire.
Caution:
Do not use anything other than the correct capacity breaker and fuse. Using fuse, wire or copper wire with too
large capacity may cause a risk of malfunction or fire.
−Be sure to take power from the special branch circuit
−Install the unit to prevent any of the control circuit cables coming into direct contact with power
cables
−Ensure that there is no slack on all wire connections
−Never connect the power cable to leads for the transmission cables. This will damage the
transmission cables

8. Connecting I/O
Caution:
Only use shielded cables for connecting sensors to MelcoREMOTE, to reduce the possibility of interference
with radio communications services. Using shielded cables ensures that you maintain the appropriate EMC
classification for the intended environment.
All shields must be tied to an appropriate Earth point within the installation panel.
8.1. Connecting Inputs
For all input types Belden 8760 type cable is recommended.
8.1.1. 0-10V Inputs
The maximum cable length for 0-10V inputs is 250m. This represents a deviation of < 1%.

Page 17 of 52
8.1.2. Resistance (10K Thermistor) Inputs
The maximum cable length for resistance type inputs is 250m. This represents a deviation of < 1% at 25ºC for 10K
thermistors.

8.1.3. Digital Inputs
The maximum cable length for digital inputs is 1000m. This represents a cable loss of < 0.1V.
8.1.4. 4-20mA Inputs

Page 19 of 52
To connect a 4-20mA sensor that requires “loop” power:
- Isolate the MelcoREMOTE supply.
- Connect the positive (+) terminal on the sensor to the RS-485 Port 1+ or RS-485 Port 2+ terminal on the
MelcoREMOTE.
- Connect the negative (-) terminal on the sensor to the required positive (+) configurable input terminal on
MelcoREMOTE (e.g. IN01+).
The maximum cable length for 4-20mA inputs is 1000m. This represents a cable loss of < 5V at 25mA.
8.2. Connecting Outputs
For connecting contactors (nominal 100mA coil) to digital outputs, the maximum cable length is 50 metres (16/0.2, tri-
rated cable). This represents a cable loss of <1V @ 80mA (typical contactor current).

9. Connecting Mitsubishi Centralised Controllers
MelcoREMOTE can be used to connect to one or more Mitsubishi centralised controllers, such as the AE-200, EW-50,
AG-150, G-50 and GB-50, via Ethernet. It can be configured to access data for all A/C Groups setup on the centralised
controller. Certain A/C settings can be changed such as Drive, Setpoint, Mode, Air Direction, Fan Speed, whilst values
such as the Return Air Temperature can be monitored.
9.1. Connection using crossover cable
If a single centralised controller is to be connected to the MelcoREMOTE then a direct connection between the two can
be made using a crossover cable.
9.2. Connection through a switch/hub
As an alternative to using a direct connection with crossover cable, the connection through an Ethernet hub or switch
can be used instead. This method must be used if more than one centralised controller is to be connected to
MelcoREMOTE.
When using a switch/hub all Ethernet cable must be the straight-through type, as opposed to the crossover type.
Switch/Hub
