RBC­TBPTS SMART Touch Controller

IMPORTANT INFORMATION

WARNING
1. Using the specified wires, ensure to connect the
wires, and fix wires securely so that the external
tension to the wires do not affect the connecting
part of the terminals.
Incomplete connection or fixation may cause a fire,
etc.
2. Be sure to connect earth wire. (grounding work)
Incomplete grounding cause an electric shock. Do
not connect ground wires to gas pipes, water pipes,
lightning rods or ground wires for telephone wires.
3. Appliance shall be installed in accordance with
national wiring regulations.
Capacity shortage of power circuit or incomplete
installation may cause an electric shock or a fire.
CAUTION
 If incorrect/incomplete wiring is carried out, it will cause
an electrical fire or smoke.
 Be sure to install an earth leakage breaker that is not
tripped by shock waves.
If an earth leakage breaker is not installed, an
electric shock may be caused.
 Be sure to use the cord clamps attached to the
product.
 Do not damage or scratch the conductive core and
inner insulator of power and inter-connecting wires
when peeling them.
 Use the power cord and Inter-connecting wire of
specified thickness, type, and protective devices
required.
 Never connect 220-240V power to the terminal blocks
( A , B , U1/U2, U3/U4 etc.) for control wiring
(Otherwise, the system will fail).
REQUIREMENT
 For power supply wiring, strictly conform to the Local
Regulation in each country.
 For wiring of power supply of the outdoor units, follow
the Installation Manual of each outdoor unit.
 Perform the electric wiring so that it does not come
to contact with the high-temperature part of the
pipe. The coating may melt resulting in an accident.
 After connecting wires to the terminal blocks,
provide a trap and fix wires with the cord clamp.
 Run the refrigerant piping line and control
wiring line in the same line.
 Do not turn on the power of the indoor unit until
vacuuming of the refrigerant pipes completes.
 Power supply wire and
communication wires
specifications
Power supply wire and communication wires are
procured locally.
For the power supply specifications, follow to the
table below. If capacity is little, it is dangerous
because overheat or seizure may be caused. For
specifications of the power capacity of the outdoor
unit and the power supply wires, refer to the
Installation Manual attached to the outdoor unit.
Indoor unit power supply
 For the power supply of the indoor unit, prepare the
exclusive power supply separated from that of the
outdoor unit.
 Arrange the power supply, earth leakage breaker,
and main switch of the indoor unit connected to the
same outdoor unit so that they are commonly used.
 Power supply wire specification : Cable 3-core
2
2.5mm , in conformity with Design 60245 IEC 57.
 Power supply
Power
supply
Power supply switch/Earth leakage breaker or power
supply wiring/fuse rating for indoor units should be
selected by the accumulated total current values of
the indoor units.
Power supply wiring
Control wiring, Central controller wiring
 2-core with polarity wires are used for the Control
wiring between indoor unit and outdoor unit and
Central controller wiring.
 To prevent noise trouble, use 2-core shield wire,
 The length of
the communication line means the total
length of the inter-unit wire length between indoor and
outdoor units added with the central control system
