Control Wiring; Access; Control Terminal Types - GE AF-600 FP Operating Instructions Manual

Installation
•
Ground the cable in accordance with grounding
instructions provided in 2.4.2 Earth (Grounding)
Requirements
•
All frequency converters may be used with an
isolated input source as well as with ground
reference power lines. When supplied from an
isolated mains source (IT mains or floating delta)
or TT/TN-S mains with a grounded leg (grounded
delta), set SP-50 RFI Filter to OFF. When off, the
internal RFI filter capacitors between the chassis
and the intermediate circuit are isolated to avoid
damage to the intermediate circuit and to reduce
earth capacity currents in accordance with IEC
61800-3.

2.4.5 Control Wiring

•
Isolate control wiring from high power
components in the drive.
•
If the drive is connected to a thermistor, for PELV
isolation, optional thermistor control wiring must
be reinforced/double insulated. A 24 VDC supply
voltage is recommended.

2.4.5.1 Access

•
Remove access cover plate with a screw driver.
See Illustration 2.13.
•
Or remove front cover by loosening attaching
screws. See Illustration 2.14.
Tightening torque for front cover is 2.0Nm for
unit size 15 and 2.2Nm for unit sizes 2X and 3X.

2.4.5.2 Control Terminal Types

Illustration 2.18 shows the removable drive connectors.
Terminal functions and default settings are summarized in
Table 2.2.
Illustration 2.15 Control Terminal Locations
•
Connector 1 provides four programmable digital
inputs terminals, two additional digital terminals
programmable as either input or output, a 24V
DC terminal supply voltage, and a common for
optional customer supplied 24V DC voltage
•
Connector 2 terminals (+)68 and (-)69 are for an
RS-485 serial communications connection
•
Connector 3 provides two analog inputs, one
analog output, 10V DC supply voltage, and
commons for the inputs and output
