Notes:
•
The minimum specified wire size does not necessarily have sufficient current carrying capacity at maximum load.
•
The terminals do not accept a conductor that is one size larger than the maximum specified wire size.
•
The maximum number of conductors per terminal is 1.
Weights and free space requirements
This table shows the requirements for the ambient conditions when the drive is in operation (installed for stationary use).

Safe torque off (STO)
The drive has a Safe torque off function (STO) in accordance with IEC/EN 61800-5-2. It can be used, for example, as the final
actuator device of safety circuits that stop the drive in case of danger (such as an emergency stop circuit).
When activated, the STO function disables the control voltage of the power semiconductors of the drive output stage, thus
preventing the drive from generating the torque required to rotate the motor. The control program generates an indication
as defined by parameter
31.22
activation switch deactivates the STO. Any faults generated must be reset before restarting.
The STO function has a redundant architecture, that is, both channels must be used in the safety function implementation.
The safety data given is calculated for redundant use, and does not apply if both channels are not used.
WARNING! The STO function does not disconnect the voltage from the main and auxiliary circuits of the drive.
Notes:
•
If stopping by coasting is not acceptable, stop the drive and machinery using the appropriate stop mode before
activating the STO.
•
The STO function overrides all other functions of the drive.
Wiring
The safety contacts must open/close within 200 ms of each other.
Double-shielded twisted-pair cable is recommended for the connection. The maximum length of the cabling between the
switch and the drive control unit is 300 m (1000 ft). Ground the shield of the cable at the control unit only.
Validation
To ensure the safe operation of a safety function, a validation test is required. The test must be carried out by a competent
person with adequate expertise and knowledge of the safety function. The test procedures and report must be
documented and signed by this person. Validation instructions of the STO function can be found in the drive hardware
manual.

0 ... 4000 m (0 ... 13123 ft) above sea level. The output current must be derated at
altitudes above 1000 m (3281 ft). The derating is 1% for each 100 m (328 ft) above
1000 m (3281 ft).
Above 2000 m (6562 ft), these grounding systems are permitted: TN-S (center-
grounded wye), TT, and IT (ungrounded or high-resistance symmetrically grounded).
For the installation requirements for corner-grounded systems at this altitude, contact
your local ABB representative.
-15 ... +50 °C (5 ... 122 °F). No frost permitted. The rated output current must be
derated by 1% for each 1 °C (1.8 °F) above 40 °C (104 °F).
5 ... 95%. No condensation permitted. Maximum permitted relative humidity is 60% in
the presence of corrosive gases.
Chemical gases: Class 3C2.
Solid particles: Class 3S2. No conductive dust permitted.
