• Wire your 24 V DC load to the heavy-duty output screw terminals using suitable wire cross-sections.

Maintenance Tips:

• Routinely inspect screw terminal connections to ensure conductors remain tight against machine vibration.
• Keep top and bottom cooling vents clean and free from industrial dust, lint, or oil residue.
• Monitor front-panel diagnostic LEDs regularly during routine cabinet audits.

Safety Instructions:

• Always isolate all 3 input AC power phases before performing any mounting, wiring, or servicing tasks.
• Installation must be conducted exclusively by qualified electrical personnel or automation engineers.
• Do not operate the unit in wet or dirty environments without placing it inside a suitable protective panel (IP20 rating).
