These heaters are controlledby an automatic thermostat and help control humidityinside the enclosure. The thermostat default settings turnon the heaters at 10 °C (50 °F) and turn them off at 15.6°C (60 °F).Cabinet light with power outletA light mounted on the cabinet interior of F-framefrequency converters increases visibility during servicingand maintenance. The housing includes a power outlet fortemporarily powering tools or other devices, available in 2voltages:• 230 V, 50 Hz, 2.5 A, CE/ENEC• 120 V, 60 Hz, 5 A, UL/cULTransformer Tap Set-upIf the cabinet light & outlet and/or the space heaters &thermostat are installed, transformer T1 requires its taps tobe set to the proper input voltage. A 380-480/500 V drivewill initially be set to the 525 V tap and a 525-690 V drivewill be set to the 690 V tap to ensure no over-voltage ofsecondary equipment occurs if the tap is not changedbefore applying power. See Table 3.11 to set the propertap at terminal T1 located in the rectifier cabinet.Input voltage range Tap to select380 V-440 V 400 V441 V-490 V 460 V491 V-550 V 525 V551 V-625 V 575 V626 V-660 V 660 V661 V-690 V 690 VTable 3.11 Transformer Tap SetupSelection Design GuideMG16C202 Danfoss A/S © Rev. 05/2014 All rights reserved. 593 3
