ABB ACS580-07-0495A-4 User Manual

Operation principle and hardware description 33
 Degree of protection
Definitions
According to IEC/EN 60529, the degree of protection is indicated by an IP code where the
first numeral means protection against ingress of solid foreign objects, and the second
numeral protection against ingress of water. The IP codes of the standard cabinet and
options covered in this manual are defined below.
IP42 and UL Type 1 Filtered (standard)
The air inlet gratings are covered with a metallic mesh between the inner metallic grating
and the outer plastic grating.
IP54 and UL Type 12 (option +B055)
This option provides the degree of protection of IP54 (UL type 12). It equips the cabinet air
inlets with filter housings containing folded board air filter mats between the inner metallic
grating and the outer plastic grating. An additional fan on the cabinet roof is included.
 Empty cubicles (options +C196 to +C201)
These options provide an empty cubicle to the drive cabinet:
• on the right-hand side of the converter cubicle (400 mm wide with option +C196,
600 mm wide with option +C197 and 800 mm wide with option +C198)
• on the left-hand side of the converter cubicle (400 mm wide with option +C199,
600 mm wide with option +C200 and 800 mm wide with option +C201).
 du/dt filter (option +E205)
The du/dt filter protects the motor insulating system by reducing the voltage rise speed at
the motor terminals. The filter also protects the motor bearings by reducing the bearing
currents.
More information on when the option is required: See section Examining the compatibility
of the motor and drive on page 50.
 Cabinet heater with external supply (option +G300)
The option contains:
• 50 W heating elements in the cubicles where needed
• load switch for providing electrical isolation during service
• miniature circuit breaker for overcurrent protection
• terminal block for external power supply.
The heater prevents humidity condensation inside the cabinet when the drive is not
running. The power output of the semiconductor-type heating elements depends on the
environmental temperature. The customer must switch the heating off when it is not
needed by cutting the supply voltage off.
The customer must supply the heater from an external 110…240 V AC power source.
