41 F600 Step By Step Guide
A.13 Transient Surge Suppression
Frames sizes 7 & 8 – 575 V ratings
Transient surge suppression shall be installed on the line side of this equipment and shall be rated to
575 Vac (phase to ground), 575 Vac (phase to phase), suitable for overvoltage category III, and shall
provide protection for an impulse withstand voltage peak of 6 kV and a clamping voltage of maximum
2400 V.
A.14 Dynamic braking
The drives have not been evaluated for dynamic braking.
A.15 External Class 2 supply
Frame sizes 7 to 11
The external power supply shall be marked with the following: “Class 2” and the power supply shall
not exceed 24 Vdc.
A.16 Modular Drive Systems
Products with DC+ and DC- supply connections have been investigated for use in Modular Drive
Systems as inverters when supplied by the converter sections from the Unidrive-M or Mentor MP
range. In these applications the inverters are required to be additionally protected by supplemental
fuses.
