4.3 Typical Wiring Diagram
Figure4. 8 Wiring diagram.
Notice:
1. Inverters between 18.5KW and 90KW have built-in DC reactor which is used
to improve power factor. For inverters above 110KW, it is recommended to
install DC reactor between P1 and (+).
2. The inverters below 18.5KW have build-in braking unit. If need braking, only
need to install braking resistor between PB and (+).
3. For inverters above (including) 18.5KW, if need braking, should install
external braking unit between (+) and (-).
4. +24V connect with PW as default setting. If user need external power supply,
disc24V with PW and connect PW with external power supply.
