11.4.2 Connecting Requirement

The equipment’s power supply 1 complies with IEC/EN 61000-3-12, provided that the short-circuit power S
sc
is
greater than or equal to 650kW at the interface point between the user’s supply and the public system. It is the
responsibility of the installer or user of the equipment to ensure, by consultation with the distribution network
operator if necessary, that the equipment is connected only to a supply with a short-circuit power S
sc
greater than
or equal to 650kW.

The equipment’s power supply 1 complies with IEC/EN 61000-3-11, shall be connected to a suitable supply
network, with the following maximum permissible system impedance Z
max
at the interface for models: 0.222 Ω
Please liaise with supply authority to ensure that the power supply 1 is connected only to a supply of that
impedance or less.

The equipment’s power supply 2 complies with IEC/EN 61000-3-12.

The equipment’s power supply 2 complies with IEC/EN 61000-3-11, shall be connected to a suitable supply
network, with the following maximum permissible system impedance Z
max
at the interface for models: 0.236 Ω
Please liaise with supply authority to ensure that the power supply 2 is connected only to a supply of that
impedance or less.
11.4.3 Wired Remote Control Instalation
WARNING
Do not modify the length of the remote control cable. Otherwise, it will cause fi re or electrical shock.
Be sure to turn off the main power before installing and connecting the remote control. Otherwise, it will cause the electrical shock.
Use the attached accessories parts and specified parts for installation. Otherwise, it will cause the set to fall, fire or electrical shock.
If passing the remote control cable through a wall, be sure to install a water trap above the cable. Otherwise, it will cause the
electrical shock.
CAUTION
Install in a flat surface to avoid warping of remote control, else damage to the LCD case or operation problems may result.
Avoid installing the remote control cable near refrigerant pipes or water pipes, else will cause electrical shock or fire.
Install the remote control cable at least 5 cm away from electric wires of other appliances to avoid miss operation (electromagnetic
noise).
Be sure to use only the accessory screws to avoid damage of remote control PCB.
