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 is set initially to the 525 V tap and a
525-690 V frequency converter is set to the 690 V tap to
insure no overvoltage of secondary equipment occurs if
the tap is not changed before power is applied. See
to set the proper tap at terminal T1 located in
the rectifier cabinet. For location in the frequency
converter, see
.

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
frequency converter 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 frequency converter’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]
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

IEC Emergency Stop with Pilz Safety Relay
Includes a redundant 4-wire emergency-stop push-button
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.
Safe Stop + Pilz Relay
Provides a solution for the "Emergency Stop" option
without the contactor in F-Enclosure frequency converters.
Manual Motor Starters
Provides 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 2 starters are allowed
(one if a 30 A, fuse-protected circuit is ordered). Integrated
into the frequency converter’s safe-stop circuit.
Unit features include:
•
Operation switch (on/off)
•
Short-circuit and overload protection with test
function
•
Manual reset function
30 A, Fuse-Protected Terminals
•
3-phase power matching incoming mains voltage
for powering auxiliary customer equipment
•
Not available if 2 manual motor starters are
selected
•
Terminals are off when the incoming power to
the frequency converter is off
•
Power for the fused protected terminals will be
provided from the load side of any supplied
contactor, circuit breaker, or disconnect switch.
24 V DC Power Supply
•
5 A, 120 W, 24 V DC
•
Protected against output over-current, overload,
short circuits, and over-temperature
•
For powering customer-supplied accessory
devices such as sensors, PLC I/O, contactors,
temperature probes, indicator lights, and/or other
electronic hardware
•
Diagnostics include a dry DC-ok contact, a green
DC-ok LED, and a red overload LED
