4.4.2 Installation of Mains Shield for
Frequency Converters
The mains shield is for installation with D and E frames
and satisfy BG-4 requirements.
Ordering numbers:
D frames: 176F0799
E frames: 176F1851
NOTE
For further information, please see the Instruction Sheet,

4.5 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. The thermostat default settings turn on the
heaters at 10° C (50° F) and turn them off at 15.6° C (60°
F).
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:
•
230 V, 50 Hz, 2.5 A, CE/ENEC
•
120 V, 60 Hz, 5 A, 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 V
frequency converter will initially be set to the 525 V tap
and a 525-690 V frequency converter 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 Table 4.13 to set the proper tap at terminal T1
located in the rectifier cabinet. For location in the
frequency converter, see Illustration 4.14.
Input Voltage Range
Tap to Select
380 V-440 V 400 V
441 V-490 V 460 V

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 terminology). 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).
•
Integrated into the drive’s safe-stop circuit
•
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
•
Fault memory
•
TEST/RESET key
Insulation Resistance Monitor (IRM)
Monitors the insulation resistance in ungrounded systems
(IT systems in IEC terminology) between the system phase
conductors and ground. There is an ohmic pre-warning
and a main alarm set-point for the insulation level.
Associated with each set-point is an SPDT alarm relay for
external use.
NOTE
Only one insulation resistance monitor can be connected
to each ungrounded (IT) system.
•
Integrated into the frequency converter’s safe-
stop circuit
•
LCD display of the ohmic value of the insulation
resistance
•
Fault Memory
•
[Info], [Test], and [Reset] buttons
IEC Emergency Stop with Pilz Safety Relay
Includes a redundant 4-wire emergency-stop push-key
mounted on the front of the enclosure and a Pilz relay that
monitors it in conjunction with the frequency converter’s
safe-stop circuit and the mains contactor located in the
options cabinet.
Manual Motor Starters
Provide 3-phase power for electric blowers often required
for larger motors. Power for the starters is provided from
the load side of any supplied contactor, circuit breaker, or
disconnect switch. Power is fused before each motor
starter, and is off when the incoming power to the
frequency converter is off. Up to two starters are allowed
(one if a 30 A, fuse-protected circuit is ordered). Integrated
into the frequency converter’s safe-stop circuit.
