Electrical Installation 11/03
SINAMICS G150
4-4 Operating Manual
Item Activity Fulfilled/Complete
16 Option L59
EMERGENCY
OFF category 1
(230 V AC)
EMERGENCY OFF category 1 stops the drive in a
controlled manner. With this option, it may be necessary
to implement braking units (brake chopper and external
braking resistors) due to the load characteristic and to
achieve the required shutdown times. No additional
wiring is necessary when implemented in conjunction
with option L45. If the cabinet unit is integrated in an
external safety circuit, however, the contact must be
looped in via terminal block -X120 (see Section 4.9.8).
17 Option L60
EMERGENCY
OFF category 1
(24 V DC)
EMERGENCY OFF category 1 stops the drive in a
controlled manner. With this option, it may be necessary
to implement braking units (brake chopper and external
braking resistors) due to the load characteristic and to
achieve the required shutdown times. No additional
wiring is necessary when implemented in conjunction
with option L45. If the cabinet unit is integrated in an
external safety circuit, however, the contact must be
looped in via terminal block -X120 (see Section 4.9.9).
18 Option L61/L62
Braking unit
The connecting cables and ground for the braking
resistor must be connected to terminal block –X5:
R1/R2. A connection must be established between the
braking resistor thermostat and customer terminal block
–A60. The settings for evaluating the thermostat as
"External Fault 3" must be made (see 4.9.10).
19 Option L83
Thermistor
motor
protection unit
(warning)
The PTC thermistor sensors (PTC resistor type A) must
be connected to the thermistor motor protection unit
-F127 at terminals T1 and T2 for warning (see Section
4.9.11).
20 Option L84
Thermistor
motor
protection unit
(shutdown)
The PTC thermistor sensors (PTC resistor type A) must
be connected to the thermistor motor protection unit
-F125 at terminals T1 and T2 for shutdown (see Section
4.9.11).
21 Option L86
PT100
evaluation unit
The resistor thermometers must be connected to
evaluation unit -A140 for the PT100 evaluation. The two-
wire or three-wire system can be used here to connect
the PT100 sensors. The sensors are divided into two
groups (see Section 4.9.12). This must be taken into
account when the evaluation is performed (factory
setting).
