Wiring the Active Converter
Control Cassette I/O
Terminals

All wiring should be installed in conformance with the applicable local,
national, and international codes (e.g., NEC/CEC). Signal wiring, control
wiring, and power wiring must be routed in separate conduits to prevent
interference with drive operation. Use grommets, when hubs are not
provided, to guard against wire chafing.

Important points to remember about I/O wiring:

Use Copper wire only. Wire gauge requirements and recommendations
are based on 75 degrees C. Do not reduce wire gauge when using higher
temperature wire.

Wire with an insulation rating of 600V or greater is recommended.

Control and signal wires should be separated from power wires by at
least 0.3 meters (1 foot).

Important: I/O terminals labeled “(–)” or “Common” are not referenced to

earth ground and are designed to greatly reduce common mode
interference. Grounding these terminals can cause signal noise.

Terminal blocks P1 and P2, shown in

Figure 1.1

and

Figure 1.3

, contain

connection points for all inputs, outputs, and power connections to the
Active Converter control cassette.

1. Remove the terminal block plug from the socket, and make connections.

2. Reinstall the terminal block plug when wiring is complete. The terminal

blocks have keys, which make it difficult to insert a terminal block plug
into the wrong socket.

!

ATTENTION: Do not route signal and control wiring with
power wiring in the same conduit. This can cause interference
with drive operation. Failure to observe this precaution could
result in damage to, or destruction of, the equipment.
