STI-24IO
The STI-24IO interface board allows access to all digital input and output signals. The STI-24IO mounts directly to
the digital I/O connector (J3) on the front of the EP drive. See figure 47 below.
Shield connection points are connected to the shell of the 26 pin “D” connector on the STI-24IO.
The STI-24IO wire range is #18 to 24 AWG stranded insulated wire.
Wiring should be done with consideration for future troubleshooting and repair. All wiring should be either color
coded and/or tagged with industrial wire tabs. Low voltage wiring should be routed away from high voltage wiring.

Do not allow ESD directly to terminals. Always discharge static electricity to enclosure, not the drive when
performing maintenance.
