Adaptors for Connection of Air Conditioners Si30-408
222 Appendix
2. The limits for wiring (i.e., Maximum distance: 1000 m, Total wiring length: 2000 m, and
Maximum number of branches: 16) should be applied to each adapter unit.
In the ranges of A, B, and C, wirings of 1000-m maximum distance, 2000-m total wiring length, and 16
maximum branches are enabled, respectively.
3. System design to diversify the risk of centralized control is enabled.
Conventional system
Faulty wirings, such as the application of 220-240V, may cause the system down.
If the expander adapter is used
Even though only the system goes down at the adapter downward, influence on the entire
system can be avoided.
