3.5 Frame size F Panel Options
3.5.1 Frame Size F 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 heat-
ers 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 con-
verters increase visibility during servicing and maintenance. The hous-
ing 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 in-
put voltage. A 380-480/ 500V drive will initially be set to the 525V tap
and a 525-690V drive will be set to the 690V tap to insure no over-volt-
age 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 ter-
minal T1 located in the rectifier cabinet. For location in the drive, see
illustration of rectifier in par. .

NAMUR Terminals
NAMUR is an international association of automation technology users
in the process industries, primarily chemical and pharmaceutical indus-
tries 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 button
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 insu-
lation level. Associated with each set-point is an SPDT alarm relay for
external use. Note: only one insulation resistance monitor can be con-
nected to each ungrounded (IT) system.
•
Integrated into the drive’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-button mounted on
the front of the enclosure and a Pilz relay that monitors it in conjunc-
tion with the drive’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 con-
tactor in F-Frame drives.
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
drive is off. Up to two starters are allowed (one if a 30A, fuse-protected
circuit is ordered). Integrated into the drive’s safe-stop circuit.
Unit features include:
•
Operation switch (on/off)
•
Short-circuit and overload protection with test function
•
Manual reset function
30 Ampere, Fuse-Protected Terminals
•
3-phase power matching incoming mains voltage for powering
auxiliary customer equipment
•
Not available if two manual motor starters are selected
•
Terminals are off when the incoming power to the drive is off
•
Power for the fused protected terminals will be provided from
the load side of any supplied contactor, circuit breaker, or dis-
connect switch.
24V DC Power Supply
•
5 amp, 120W, 24V DC
•
Protected against output over-current, overload, short circuits,
and over-temperature
