Warnings!
ƒ Use 60/75 °C copper wire only, except for control circuits.
ƒ Suitable for use in a surrounding air temperature of 40 °C, and additionally
55 °C when the derating rules are followed.
ƒ Voltage of the fuses must at least be suitable for the input voltage of the
drive.
ƒ The opening of branch circuit protective device may be an indication that a
fault has been interrupted. To reduce the risk of fire or electric shock,
current−carrying parts and other components of the controller should be
examined and replaced if damaged.
ƒ For E70ACPS0304x AC/DC power supply module only:
– Suitable for use on a circuit capable of delivering not more than 100 k rms
symmetrical amperes, 480 V max,
– when protected by class J, T or G fuses or protected by a circuit breaker
having an interrupting rating not less than 100 k rms symmetrical
amperes, 480 V.
– Use fuses or circuit breakers only.
ƒ For E70ACPS0604x AC/DC power supply module only:
– Suitable for use on a circuit capable of delivering not more than 100 k rms
symmetrical amperes, 480 V max,
– when protected by class J, T or G fuses.
– Use fuses only.
