| Note) |
For the inverter type FRNF50C1-2U**, the symbol o is replaced with either of the following letters and ** is replaced with any of the following numeral codes:
: S (Standard type), E (EMC filter built-in type), ** : 21 (Braking resistor built-in type), None (Standard type)
The inverter applicable to RS-485 communication is limited to the standard ones in three-phase 230V and three-phase 460V series.
The braking resistor built-in type is limited to the inverters rated 2HP or larger. |

For molded-case circuit breakers (MCCB) and a ground-fault circuit interrupter (GFCI), the required frame type and series depend on the facility transformer capacity and other factors. When selecting optimal breakers, refer to the relevant technical data. Also select the rated sensitive current of GFCI utilizing the technical data. The above rated currents of MCCB and GFCI are for the breakers SAB/ and SAR/. |
| |
- |
The recommended wire sizes are based on the temperature inside the panel not exceeding 50°C (122°F). |
| |
- |
The above wires are 600V HIV insulated solid wires (75°C (167°F)). |
