Installation & Maintenance Guide

Installation Requirements:

1. Cut out the electrical cabinet panel door according to the official Delta 3.8-inch DOP cutout dimensions.
2. Fit the HMI unit into the cutout and tighten the mounting clips evenly to ensure an IP65 front seal.
3. Allow sufficient clearance behind the rear casing for natural ventilation and wiring cable clearance.
4. Supply a regulated, clean 24 VDC power source with proper frame grounding to protect internal electronics against power surges.

Maintenance Tips:

1. Clean the display surface gently using a soft, clean dry cloth. Avoid harsh chemical cleaners, alcohol, or abrasive cloths.
2. Keep surrounding ventilation openings on the cabinet door dust-free.
3. Maintain backed-up copies of the HMI screen project files on a computer drive for quick field replacement.

Safety Instructions:

• Always turn off the main input power before carrying out wiring or installation work.
• Verify 24 VDC input power polarity before powering on the unit to prevent internal board damage.
• Do not touch or press the screen using sharp tools, screwdrivers, or excessive force.
