• The electrical power line and signal lines must be fastened tightly.
• Every indoor unit must have the ground connection.
• The power line should be enlarged if it exceeds the permissible length.
• Shielded lays of all the indoor and outdoor units should be connected together, with the shielded lay at the side of signal
lines of outdoor units grounded at one point.
• It is not permissible if the whole length of signal line exceeds 1000m.
