220V AC/5 A. For detailed information, see Table 14 and Table 15 on page 66.
These outputs are scalable depending on user requirements.
EtherNet/IP™ interface is supplied as standard (other communication
interfaces including Modbus TCP, Modbus Plus, Modbus RTU, and PROFIBUS
are provided as options).
Wiring Routing and Connection
The control signal wiring enters the drive through the same opening as the
control power wiring in the LV Control Cabinet (Figure 22
).
The wiring terminates to the VFD1 terminal block strips on the sides of the LV
Control cabinet (Figure 23
).
Connect Electrical Safety
Interlock Circuit to Input
Circuit Breaker
The electrical safety interlock circuit is part of the overall control signal wiring
activity. However, it is mentioned separately in this document due to its
critical importance related to the safe operation of the drive and personnel
safety.
The circuits that are connected between the drive and the input circuit
breaker:
• allow the drive to trip the input circuit breaker if a drive cabinet door is
opened. This applies to the cabinet doors where medium voltage is
present. The LV Control cabinet door can be opened while the drive is
energized.
• allow the drive to prevent the input circuit breaker from closing when
required.
• indicate to the drive when the input circuit breaker is closed.
MV Door Safety Interlock
If the MV cabinet door is opened, the Allen-Bradley Guardmaster® Limit
Switch (440P-CRPS11D4B) on the cabinet door will actuate. The drive will send
a trip signal to the input circuit breaker to disconnect the medium voltage
power supply to the drive.
ATTENTION: The door position interlock is a safety feature. It must not be
used solely as a part of the plant operation process to ensure the drive has
been disconnected from input medium voltage. Keep the medium voltage
doors locked as standard practice. Always go to the input circuit breaker
feeding the drive to verify if it is open. Lock out and tagout the input circuit
breaker before performing any work on the drive or bypass units.
