Installation Information

Disconnect the machine power supply before installation. Inspect the equipment-side connectors, terminals and wiring harness for bent pins, corrosion, loose terminals, water damage or short circuits. A damaged machine-side harness may damage the replacement monitor.

Professional installation is recommended. Depending on the machine serial number and configuration, initialization, calibration or software matching may be required. Do not assume plug-and-play compatibility from the machine model alone.
