Installation Guide
Rack Mounting Steps
Insert the 3500/60-01-01 monitor into any front slot. Place the matching I/O module into the rear slot. Push both modules firmly until they lock. Secure them using the locking tabs.

Wiring Instructions
Connect your RTD or TC wires to the I/O module terminals. Use shielded cables for better noise immunity. Keep wire runs as short as possible. Follow the termination label on your I/O module.

Software Setup
Open the 3500 Configuration Software. Select each channel and choose your sensor type. Set the measurement range for every channel. Save the configuration to the rack.
