Note the following when selecting wiring
R Use 2-conductor (solid copper) wiring with a PE (polyethylene)-insulated PVC jacket.
Mid-capacitance, non-shielded cable is recommended.
R A certified power supply wiring has to be used with this equipment. The relevant national installation and/or
equipment regulations shall be considered. A certified power supply wiring not lighter than ordinary polyvinyl
chloride flexible wiring according to IEC 60227 shall be used.
R When an extension box is connected, the maximum wire length from the lobby station to the distributor does not
change.
