F-Frame Options - Danfoss VLT FC 102 Operating Instructions Manual

Electrical Installation
Stop the AMA during operation
Successful AMA
•
The display shows Press [OK] to finish AMA.
•
Press [OK] to exit the AMA state.
Unsuccessful AMA
•
The frequency converter enters into alarm mode.
A description of the alarm can be found in
chapter 7 Diagnostics and Troubleshooting.
•
Report value in the alarm log shows the last
measuring sequence carried out by the AMA
before the frequency converter entered alarm
mode. This number, along with the description of
the alarm, helps with troubleshooting. Mention
the number and alarm description when
contacting Danfoss service personnel.
Unsuccessful AMA is the result of incorrectly registered
motor nameplate data or too large a difference between
the motor power size and the frequency converter power
size.

Space heaters and thermostat
There are space heaters mounted on the cabinet interior of
F-frame frequency converters. These heaters are controlled
by an automatic thermostat and help control humidity
inside the enclosure. 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 F-frame
frequency converters increases visibility during servicing
and maintenance. The housing includes a power outlet for
temporarily powering tools or other devices, available in 2
voltages:
•
230 V, 50 Hz, 2.5 A, CE/ENEC
•
120 V, 60 Hz, 5 A, UL/cUL
Transformer tap set-up
If the cabinet light, outlet, and/or the space heaters, and
thermostat are installed, transformer T1 requires its taps to
be set to the proper input voltage. A 380–480/500 V
frequency converter is initially set to the 525 V tap, to
ensure that no overvoltage of secondary equipment occurs
if the tap is not changed before applying power. See
Table 4.15 to set the proper tap at terminal T1 located in
the rectifier cabinet.

NAMUR terminals
NAMUR is an international association of automation
technology users in the process industries, primarily
chemical and pharmaceutical industries in Germany.
Selecting this option, provides terminals organised and
labeled to the specifications of the NAMUR standard for
frequency converters input and output terminals. This

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 the
customer).

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 setpoint for the insulation level. An SPDT
