4.8 Control Wiring
•
Isolate control wiring from high power
components in the adjustable frequency drive.
•
When the adjustable frequency drive is
connected to a thermistor, ensure that the
thermistor control wiring is shielded and
reinforced/double insulated. A 24 V DC supply
voltage is recommended.
4.8.1 Control Terminal Types
Figure 4.11 and Figure 4.12 show the removable adjustable
frequency drive connectors. Terminal functions and default
settings are summarized in Table 4.2.

Figure 4.12 Terminal Numbers
•
Connector 1 provides four programmable digital
inputs terminals, two additional digital terminals
programmable as either input or output, a 24 V
DC terminal supply voltage, and a common for
optional customer supplied 24 V DC voltage
•
Connector 2 terminals (+) 68 and (-) 69 are for an
RS-485 serial communication connection
•
Connector 3 provides two analog inputs, one
analog output, 10 V DC supply voltage, and
commons for the inputs and output
•
Connector 4 is a USB port available for use with
the MCT 10 Set-up Software
