3.7.7 Frame size F Panel Options
Space Heaters and Thermostat
Mounted on the cabinet interior of frame size F frequency converters, space heaters controlled via automatic thermostat help control humidity inside the
enclosure, extending the lifetime of drive components in damp environments.
Cabinet Light with Power Outlet
A light mounted on the cabinet interior of frame size F 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 380-480/ 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 over-voltage 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.

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.
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 set-point) and a main alarm set-point. Associated with each set-point is an SPDT alarm relay for
external use. Requires an external “window-type” current transformer (supplied and installed by customer).

IEC 60755 Type B device monitors AC, pulsed DC, and pure DC ground fault currents
•
LED bar graph indicator of the ground fault current level from 10–100% of the set-point
