GE Industrial Solutions AF-650 GP General Purpose Drive (460_575_690V 125HP and above) - Manual (Page 42)

3.4.3 Installation of Mains Shield for frequency converters
This section is for the installation of a mains shield for the frequency converter series with Unit Sizes 41, 42 and 51. It is not possible to install in the IP00/ Chassis
drive types as these have included as standard a metal cover. These shields satisfy VBG-4 requirements.

Please consult GE for more information.
Torque requirements
M6 - 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 consult GE.

3.5.1 Unit Size 6X Panel Options
Please note that these options are all special order. Please consult GE for more information.
Space Heaters and Thermostat
Mounted on the cabinet interior of Unit Size 6X frequency converters, space heaters controlled via automatic thermostat help control humidity inside the Unit,
extending the lifetime of drive components in damp environments.
Cabinet Light with Power Outlet
A light mounted on the cabinet interior of Unit Size 6 frequency converters increase visibility during servicing and maintenance. The housing the light includes a
power outlet for temporarily powering tools or other devices, available in two voltages:
• 230V, 50Hz, 2.5A, CE/ENEC
• 120V, 60Hz, 5A, UL/cUL
Transformer Tap Setup
If 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 380-500
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 of secondary 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 in the rectifier cabinet. For location in the drive, see
illustration of rectifier in the Power Connections section.
Input Voltage Range Tap to Select
380V-440V 400V
441V-490V 460V
491V-550V 525V
551V-625V 575V
626V-660V 660V
661V-690V 690V
NAMUR Terminals
NAMUR is an international association of automation technology users in the process industries, primarily chemical and pharmaceutical industries in Germany.
Selection of this option provides terminals organized and labeled to the specifications of the NAMUR standard for drive input and output terminals. This requires
MCB 112 PTC Thermistor Card and MCB 113 Extended Relay Card.
RCM (Residual Current Monitor)
Designed for monitoring residual leakage current to ground on supply mains (TN and TT systems), the RCM requires an external measuring transformer (supplied
and installed by customer). Two relays (N.O. or N.C. ) allow separate setpoints for pre-warning (50% of alarm threshold) and alarm conditions.
• Integrated into the drive’s safe-stop circuit
• LED bar graph indicator of residual leakage current level
• Fault memory
