Additional wire markings
The following additional wire markings are available.
Option
Additional markings
+G338
Equipment pin identifiers are marked with printing (or equivalent) on conductors that connect
(class A1)
to equipment, or are part of the wiring between power modules. (Short, obvious connections,
main circuit conductors, and conductors going to terminal blocks or plug-type connectors are
not marked.)
+G339
Equipment pin identifiers are marked with printing (or equivalent) on conductors that connect
(class A2)
to equipment or terminal blocks, or are part of the wiring between power modules. Main circuit
conductors are marked with white tape or printing. (Short, obvious connections, or conductors
going to plug-type connectors are not marked.)
+G340
Single wires not attached to plug-in connectors are marked with component pin numbers on
(class A3)
snap-on or ring markers. Plug-in connectors are marked with an identification label placed on
the wires near the connector (individual wires are not marked). Short, obvious connections
are not marked. PE wires are not marked unless connected directly to components.
+G341
Equipment designations and pin identifiers are marked with snap-on markers (or equivalent)
(class B1)
on conductors that connect to equipment, terminal blocks or detachable plug-type connectors,
or are part of the wiring between power modules. Fiber optic cables are marked in the same
way. Plug-type connector identifications are marked on labels near the connectors. The label
holders are attached around conductor bundles. Main circuit conductors are marked with white
tape or printing. Short and obvious connections are marked with printing (or equivalent) only.
Note: Even wires with equipment and pin identifiers printed on the wire insulation are marked
with rings or tubing.
+G342
Single wires connected to components, between modules, or to terminal blocks are marked
(class C1)
with component identification and pin numbers for both ends. The marking is printed on
sleeving or, if necessary, snap-on markers. Plug-in connectors are marked with an identification
label (or snap-on markers) placed on the wires near the connector (individual wires are not
marked). Short, obvious connections are not marked. PE wires are not marked unless connec-
ted directly to components.
Voltage measurement with BAMU auxiliary measurement unit (option
￭
+G442)
In weaker supply networks with a short-circuit ratio less than 8, it is highly recommended
to install a BAMU auxiliary measurement unit to the drive. In such networks, there is a risk
