3.4.5 Installation of Mains Shield for frequency convertersThis section is for the installation of a mains shield for the frequency converter series with D1, D2 and E1 frames. It is not possible to install in the IP00/Chassis versions as these have included as standard a metal cover. These shields satisfy VBG-4 requirements.Ordering numbers:Frames D1 and D2 : 176F0799Frame E1: 176F1851Torque requirementsM6 - 35 in-lbs (4.0 N-M)M8 - 85 in-lbs (9.8 N-M)M10 - 170 in-lbs (19.6 N-M)NB!For further information, please see the Instruction Sheet,175R59233.5 Frame size F Panel Options3.5.1 Frame size F Panel OptionsSpace Heaters and ThermostatMounted on the cabinet interior of frame size F frequency converters, space heaters controlled via automatic thermostat help control humidity inside theenclosure, extending the lifetime of drive components in damp environments.Cabinet Light with Power OutletA light mounted on the cabinet interior of frame size F frequency converters increase visibility during servicing and maintenance. The housing the lightincludes a power outlet for temporarily powering tools or other devices, available in two voltages:• 230V, 50Hz, 2.5A, CE/ENEC• 120V, 60Hz, 5A, UL/cULTransformer Tap SetupIf the Cabinet Light & Outlet and/or the Space Heaters & Thermostat are installed Transformer T1 requires it taps to be set to the proper input voltage.A 380-480/ 500 V380-480 V drive will initially be set to the 525 V tap and a 525-690 V drive will be set to the 690 V tap to insure no overvoltage ofsecondary equipment occurs if the tap is not changed prior to power being applied. See the table below to set the proper tap at terminal T1 located inthe rectifier cabinet. For location in the drive, see illustration of rectifier in thePower Connections section.Input Voltage Range Tap to Select380V-440V 400V441V-490V 460V491V-550V 525V551V-625V 575V626V-660V 660V661V-690V 690VNAMUR TerminalsNAMUR is an international association of automation technology users in the process industries, primarily chemical and pharmaceutical industries inGermany. Selection of this option provides terminals organized and labeled to the specifications of the NAMUR standard for drive input and outputterminals. This requires MCB 112 PTC Thermistor Card and MCB 113 Extended Relay Card.RCD (Residual Current Device)Uses the core balance method to monitor ground fault currents in grounded and high-resistance grounded systems (TN and TT systems in IEC termi-nology). There is a pre-warning (50% of main alarm setpoint) and a main alarm setpoint. Associated with each setpoint is an SPDT alarm relay for externaluse. Requires an external “window-type” current transformer (supplied and installed by customer).• Integrated into the drive’s safe-stop circuit3 How to Install VLT AQUA High Power Operation Instructions46 MG.20.P3.02 - VLT® is a registered Danfoss trademark3
