81.4.1 Safety FirstRISK OF ELECTRIC SHOCK! Always disconnect supply voltage beforeservicing the F5 Elevator Drive.After disconnecting the supply voltage, always wait 5 minutes beforeattempting to change the wiring. The internal DC BUS capacitors mustdischarge.1.4.2 Voltage SupplyThe F5 series inverters are suitable for use on a circuit capable of delivering notmore than 5kA rms symmetrical amperes, at the inverter's rated maximumvoltage.Pay attention to the supply voltage and be sure the supply voltage matches thatof the inverter. A 230V unit can be supplied with voltage in the range 180 to260VAC +/-0%, for a 460V unit the range is 305 to 500VAC +/- 0%, 48Hz to 62Hz.Connection of the F5 series inverters to voltage systems configured as acorner grounded delta, center tap grounded delta, open delta, or un-grounded delta, may defeat the internal noise suppression of the inverter.Increased high frequency disturbance in the machine and on the line maybe experienced. A balanced, center grounded wye connection is alwaysrecommended. The three phase voltage imbalance must be less than 2%phase to phase. Greater imbalance can lead to damage of the inverter'spower circuit.General1.4 Electrical connections1.3.4 Ambient ConditionsThe operating temperature range of the unit is -10°C to + 45°C (14° to+113°F). Operation outside of this temperature range can lead to shut downof 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 voltage to theinverter for 2 hours before operating the motor. This will allow the electrolytic buscapacitors to stabilize before use and result in longer lifetime of the unit.The power rating of the inverter must be derated for operation above 3,300 ft (1000m). Reduce the rated power 1% for each additional 330 ft (100 m). The maximumelevation for operation is 6,560 ft (2000 m)The relative humidity should be limited to 95% without condensation.i
