* 1. Connect using exclusive-use connection bus bar.
* 2. Provided for open chassis type with a minimum capacity of 11 kW. Not provided for external heatsink cooling type.
Notes: 1. Wire size is selected assuming external suspended wiring of single 3-core cables at
an ambient temperature of 30°C (86°F).
2. If ambient temperature exceeds 30°C (86°F), the allowable current of wire may be lowered.
3. Temperature for each wire indicates the maximum allowable conductor temperature.
