Wiring Example; Field Setting - Panasonic S-20UM3HPQ Manual De Instalación Y Funcionamiento

5 For the remote controller wiring, refer to the "Installation manual
of the remote controller" supplied with the remote controller.
6 Never connect the power supply wiring to the terminal board for
transmission wiring. This mistake could damage the entire
system.
7 Use only specified wires and tightly connect wires to the
terminals. Be careful that wires do not place external stress on
the terminals. Keep wiring in neat order so that they do not
obstruct other equipment such as popping open the service
cover. Make sure the cover closes tight. Incomplete connections
could result in overheating, and in the worse case, electric shock
or fire.

When using 1 remote controller for 1 indoor unit. (Normal
operation.) (See figure 14).
For group control or use with 2 remote controllers (See figure 16).
When including HR box (See figure 18).
NOTE It is not necessary to designate indoor unit address
when using group control. The address is automati-
cally set when the power is activated.
Precautions
1. A single switch can be used to supply power to units on the same
system. However, branch switches and branch circuit breakers must
be selected carefully.
2. For a group control remote controller, choose the remote
controller that suits the indoor unit which has the most functions.
3. Do not ground the equipment on gas pipes, water pipes,
lightning rods or crossground with telephones. Improper
grounding could result in electric shock.
