1.4 Approvals and Certifications The following list is a selection of possible type approvals and certifications for Danfoss drives: The specific approvals and certification for the enclosed drive or drive module are on the nameplate of the drive. For more informa- tion, contact the local Danfoss office or partner.
Due to export control regulations, the output frequency of the enclosed drive (with no output filters) is limited to 590 Hz. For demands exceeding 590 Hz, contact Danfoss. For enclosed drives with output filters, the maximum output frequency is limited to 60 Hz without derating and to 100/120 Hz with derating.

There is a risk for overvoltage. Isolation between components and critical parts could be insufficient and may not comply with PELV requirements. Use external protective devices or galvanic isolation. For installations above 2000 m (6500 ft) altitude, contact Danfoss re- garding protective extra low voltage (PELV) compliance.
• Danfoss recommends the fuse type gG (IEC 60269-1) for the mains fuses. Use only fuses with a sufficient voltage rating accord- ing to the mains voltage. Do not use larger fuses than what is recommended. These fuses are selected for short-circuit protec- tion only.

The control card and power card are incompatible. Troubleshooting • To check compatibility, contact the Danfoss supplier with the type code from the unit nameplate and the part numbers on the cards. 9.4.66 ALARM 71, PTC 1 Safe Stop Cause Because the motor is too warm, the VLT PTC Thermistor Card MCB 112 activated the Safe Torque Off (STO).

If the switching frequency is higher than the default setting, the power losses can increase. LCP and typical control card power consumptions are included. For power loss data according to EN 50598-2, refer to drives.danfoss.com/knowledge-center/energy-efficiency-direc- tive/#/. Options and customer load can add up to 30 W to the losses, though usually a fully loaded control card and options for slots A and B each add only 4 W.
