Use 60/75 °C copper wire only, except for control circuits.
Suitable for use in a surrounding air temperature of 40 °C, and additionally
55 °C when the derating rules are followed.
Voltage of the fuses must at least be suitable for the input voltage of the
drive.
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.
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.
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.
