Drainage Piping Work; Electrical Work - Mitsubishi Mr.Slim PUHZ-RP200YHA Manual De Instalación

6. Drainage piping work

It is possible to have the drain flow out along the bottom of the outdoor unit. Use the centralized drainage kit when using drain piping.

7. Electrical work

7.1. Outdoor unit (Fig. 7-1, Fig. 7-2)
(1) Remove the service panel.
(2) Wire the cables referring to the Fig. 7-1 and the Fig. 7-2.

7.2. Field electrical wiring
• If the wiring connecting the indoor and outdoor units is longer than 80 m, use separate indoor/outdoor unit power supplies. (Refer to the installation manuals of the indoor
units for more information.)

*1. A breaker with at least 3 mm contact separation in each pole shall be provided. Use non-fuse breaker (NF) or earth leakage breaker (NV).
*2. Max. 80 m Total Max. including all indoor/ indoor connection is 80 m.
• Use one cable for S1 and S2 and another for S3 as shown in the picture.
*3. A 10 m wire is attached in the remote controller accessory.
*4. The voltage are NOT against the ground.
S3 terminal has DC 24 V against S2 terminal. However between S3 and S1, these terminals are not electrically insulated by the transformer or other device.
Notes: 1. Wiring size must comply with the applicable local and national code.
2. Power supply cords and Indoor unit/Outdoor unit connecting cords shall not be lighter than polychloroprene sheathed flexible cord. (Design 245 IEC 57)
3. Use an earth wire which is longer than the other cords so that it will not become disconnected when tension is applied. The earth wire should also be
thicker than the power supply cord so that it can stand any surge of electricity when trouble occurs.
Warning:
In case of A-control wiring, there is high voltage potential on the S3 terminal caused by electrical circuit design that has no electrical insulation between power line
and communication signal line. Therefore, please turn off the main power supply when servicing. And do not touch the S1, S2, S3 terminals when the power is
energized. If isolator should be used between indoor unit and outdoor unit, please use 3-poles type.
