Gateway for VRF System
When connecting the cables to this unit, route the cables so that the cover of this unit is securely fixed. If the cover is
imperfectly fixed, it may cause fire or overheating of the terminals.
Perform earth (ground) work positively. Do not connect the earth (ground) cable to a telephone cable, water pipe, or
conductor rod.
Always fasten the outside covering of the cables with the cable clamp. (If the insulator is chafed, electric leakage may occur.)
Perform all wiring works so that the user does not touch the wiring. Otherwise, injury or electric shock could result.
If any cable is damaged, do not repair or modify it yourself. Improper work will cause electric shock or fire.
Do not bind the remote controller cable and the transmission cable together with or parallel to the power supply cable of the
indoor and outdoor units. It may cause erroneous operation.
When performing wiring work, be careful not to damage the cable or injure yourself. Also, connect the connectors securely.
Loose connec- tors will cause trouble, heating, fire, or electric shock.
Install the indoor and outdoor units, power supply cable, transmission cable and remote control cable 1 m (40 in.) away from
television and ra- dio to avoid distorted images and noise. Otherwise, a malfunction could result.
Perform wiring so that water does not enter this unit along the external wiring. Always install a trap to the wiring or take other
countermeasures. Otherwise it will cause trouble or electric shock or fire.
Confirm the name of each unit and name of each terminal block of the unit and connect the wiring in accordance with the
directions given in the manual so that there is no incorrect wiring. Incorrect wiring will dam- age the electric parts and cause
smoke and fire.
When installing the connection cables near a source of electromagnetic waves, use shielded cable.
Otherwise, a breakdown or malfunction could result.
The terminal screws and earth (ground) screws have different shapes. Be sure to install the screws in the correct locations. If
the screws are installed in the wrong locations, the circuit board could be damaged.
Note:
- Do not bind the power supply cable and transmission cable to avoid an erroneous operation.
- Use shield cable for transmission cable. The shield metal should be earthed (grounded).
- Install the disconnect switch to the easily accessible location.
- Check that an appropriate fuse (1.25A) is set.
- Before connecting cables, turn off the power of the VRF units connected to the gateway.
Power device
The first step to perform is to power up the device. To do so, a power supply working with any of the voltage range
allowed is needed (check section 10). Once connected the ON led will turn on.
Notes:
(1) Connect the cables to the correct terminals. Take care that the cables do not get shortened. The stripped end
of the cables are preferably be tinned.
(2) Secure the cable to the terminals using an appropriate tool so that the cables do not come loose.
(3) Use the specified cables, connect them securely, and fasten them so that there is not stress placed on the
terminals.
(4) Use an appropriate screwdriver to tighten the terninal screws.
Do not use a screw dirver that is too small or big. Otherwise, the screw heads may be damaged and prevent the
screw from being properly tightened.
(5) Do not tighten the terminal screw too much. Otherwise, the screw may break.
(6) Apply an appropriate tightening torques for the terminal screw. Otherwise, abnormal overheating may occur
and possibly cause heavy damage inside the unit,.
(7) Do not fix 2 or more power supply cables with 1 screw/terminal.
Apply an appropriate tightening torques for the terminal screw. Otherwise, abnormal overheating may occur and possibly
cause heavy damage inside the unit,.
