121.4.1 Safety FirstCAUTION - RISK OF ELECTRIC SHOCK! Always disconnect supply volt-age before servicing the F5 Elevator Drive.After disconnecting the supply voltage, always wait 5 minutes before at-tempting to change the wiring. The internal DC BUS capacitors must dis-charge.1.4.2 Voltage SupplyPay attention to the supply voltage and be sure the supply voltage matchesthat of the inverter. A 230V unit can be supplied with voltage in the range180 to 260VAC +/-0%, for a 460V unit the range is 305 to 500VAC +/- 0%,48Hz to 62 Hz.All 240V models are suitable for use on a circuit capable of delivering notmore than ___ kA rms symmetrical amperes, 240 volts maximum when pro-tected by class ___ fuses rated ___ Amperes as specified in table 1.4.4.1 orwhen protected by a circuit breaker having an interrupt rating not less than___ kA rms symmetrical amperes, 240V maximum, rated ___ amperes asspecified in table 1.4.4.1.All 480V models are suitable for use on a circuit capable of delivering notmore than ___ kA rms symmetrical amperes, 480 volts maximum when pro-tected by class ___ fuses rated ___ Amperes as specified in table 1.4.4.2 orwhen protected by a circuit breaker having an interrupt rating not less than___ kA rms symmetrical amperes, 480V maximum, rated ___ amperes asspecified in table 1.4.4.2.1.3.4 Ambient ConditionsMaximum Surrounding Air Temperature 45°C! The operating temperaturerange of the unit is -10°C to + 45°C (14° to +113°F). Operation outside ofthis temperature range can lead to shut down of the inverter.The unit can be stored (power off) in the temperature range -25°C to 70°C(-13 to +158°F). After prolonged storage, one half year or more, apply volt-age to the inverter for 2 hours before operating the motor. This will allow theelectrolytic bus capacitors to stabilize before use and result in longer lifetimeof the unit.The power rating of the inverter must be derated for operation above 3,300ft (1000 m). Reduce the rated power 1% for each additional 330 ft (100 m).The maximum elevation for operation is 6,560 ft (2000 m)The relative humidity shall be limited to 5% without condensation.General1.4 Electrical connectionsc
