INSTALLATION
(Continued)
Connecting the Power Terminal
Connecting Power/Communication cable
• Turn off the power before connecting the power terminal.
• Maximum cable length and the amount of voltage drop for AHU power/communication cables should be under 10%.
• Consider power usage of the AHU when installing the ELB.
• Connect V1, V2 on AHU KIT PBA to the power line (V1, V2) on wired remote control.
Connect F3, F4 on AHU KIT to the communication line (F3, F4) on wired remote control. (Refer to page 14)
• Use the appropriate tools for wiring and make sure to connect them tightly within the
tightening torque to withstand the external pressure. Arrange the wires so that cover
or other parts does not get loose. They may cause overheating, electric shock or fire.
• Protect the power and communication cables from flood or outer shock by putting them in a safety box.
• Connect the power cable to the ELB.
• Allow space over 50㎜ between the power and communication cable.
• Power supply for AHU KIT should be separate from outdoor unit.
�������
• Do not cut and connect the communication cable. It may cause communication error.
• Do not connect the terminal block power line from one indoor unit to more than one AHU KIT.
• When peeling the power cable, use the appropriate tools to prevent damaging the wire.
• Communication cable should be installed separately from power cable or other cables.
Selecting compressed ring terminal
1) Select the compressed ring that is appropriate for the dimension of the power cable.
2) Peel off the power cable cover when connecting to the compressed ring terminal.
