Operating Instructions, 07/07, A5E00288214A
The PTC thermistor sensors (PTC resistor type A) must be connected
to the thermistor motor protection unit -F127 at terminals T1 and T2
for alarms (see "Electrical installation / Thermistor motor protection
device (option L83/L84)").
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 "Electrical installation / Thermistor motor protection
device (option L83/L84)").
The resistor thermometers must be connected to evaluation unit
-A140 for the PT100 evaluation. A two-wire or three-wire system can
be used here to connect the PT100 sensors. The sensors are divided
into two groups (see "Electrical installation / PT100 evaluation unit
(option L86)"). This must be taken into account for the evaluation
(factory setting).
The insulation monitor can only be operated from an insulated
network. Only one insulation monitor can be used in an electrically-
connected network. For line-side control, the signaling relays must be
connected accordingly or, with individual drives (the cabinet unit is fed
via a converter transformer assigned to the cabinet unit), integrated in
the cabinet unit warning train (see "Electrical installation / Insulation
monitoring (option L87)").
Point 7 must also be taken into account:
"Before the cabinet is operated from an ungrounded supply/IT system,
the connection bracket for the basic interference suppression device
must be removed (see "Electrical installation / Removing the
connection bracket for the interference-suppression capacitor with
operation from an ungrounded supply")".
The terminal strip -X41 must be connected line-side, the safety
functions must be activated prior to use via parameter assignment, in
addition an acceptance test must be performed and an acceptance
log must be created (see chapter "Terminal module for activating
"Safe Torque Off" and "Safe Stop 1" (Option K82)").
