Information
The equipment described in this manual may cause electronic noise generated from
radio-frequency energy. The equipment complies to specifications that are designed
to provide reasonable protection against such interference. However, there is no
guarantee that interference will not occur in a particular installation.
It is therefore recommended to install the equipment and electric wires keeping
proper distances away from stereo equipment, personal computers, etc.
In extreme circumstances a distance of 3 m or more is required.

Branch the line outside the terminal block of the unit in accordance with electrical equipment standards, when
using two power wires of a gauge greater than 2 mm². The branch must be sheathed in order to provide an equal
or greater degree of insulation as power supply wiring itself.

Only in case of protected pipes. Use H07RN-F in case of no protection.
(b)
Run electrical wiring through a conduit to protect against external forces.
(c)
Use double insulation wire for remote controller (sheath thickness: ≥1 mm) or run wires through a wall or
conduit so that the user cannot come in contact with them.
