• Main circuit terminals: Connector identifier (eg. "U1") marked on terminal, or on
insulating material close to the terminal. Input and output main circuit cables are
not marked.
• Plug-in connectors of wire sets (except those that require special tools to
disconnect) are labeled with connector designation (eg. "X1"). The marking is
either directly on the connector, or near the connector on printed sleeving or tape.
• Grounding busbars are marked with stickers.
• Fiber optic cable pairs and data cables have component designation and connector
designations (eg. "A1:V1", "A1:X1") marked with rings or tape.
• Data cables are marked with tape.
• Ribbon cables are marked with either labels or tape.
• Customer-specific (engineered) wiring (option +P902) is not marked.
Additional wire markings
The following additional wire markings are available.
Additional markingsOption
Single wires not attached to plug-in connectors are marked with component pin numbers
on 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.
+G340
(class A3)
Single wires connected to components, between modules, or to terminal blocks are
marked 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 connected directly to components.

Common mode filter temperature monitoring (option +G453)
This option contains thermal switches installed within the common mode filter
assemblies of the drive. An overtemperature warning is generated when overheating
is detected.
This is primarily intended for drive systems prone to high common mode currents,
such as drive systems with long motor cabling connected to an ungrounded supply
network.
￭
Bottom cable entry/exit (options +H350 and +H352)
For UL Listed (+C129) units, the default input and output cabling direction is through
the roof of the cabinet. The bottom entry (+H350) and bottom exit (+H352) options
