Electrical Connection - Toshiba MMC-AP0157HP-E Installation Manual

Heat insulation process
Apply heat insulation for the pipes separately at liquid
side and gas side.
• For the heat insulation to the pipes at gas side, use
the material with heat-resisting temperature 120 °C
or higher.
• To use the attached heat insulation pipe, apply the
heat insulation to the pipe connecting section of the
indoor unit securely without gap.
REQUIREMENT
• Apply the heat insulation to the pipe connecting
section of the indoor unit securely up to the root
without exposure of the pipe. (The pipe exposed to
the outside causes water leak.)
• Wrap heat insulator with its slits facing up (ceiling
side).
Fix it with vinyl tape

Electrical connection

CAUTION
• If incorrect / incomplete wiring is carried out, it will cause an electrical fi re or smoke.
• Use the cord clamps attached to the product.
• Do not damage or scratch the conductive core and inner insulator of power and system interconnection wires
when peeling them.
• Use the power cord and system interconnection wire of specifi ed thickness, type, and protective devices required.
• Do not connect 220-240 V power to the terminal blocks (
will fail.)
• 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.
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.
• After connecting wires to the terminal blocks, provide a trap and fi x 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 specifi cations
Power supply wire and communication wires are locally procured.
For the power supply specifi cations, follow to the table below. If capacity is little, it is dangerous because overheat
or burnout may be caused.
For specifi cations 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, circuit breaker, and main switch of the indoor unit connected to the same outdoor unit
so that they are commonly used.
• Power supply wire specifi cation: Cable 3-core 2.5 mm², in conformity with Design 60245 IEC 57.
