- Ensure vertical mounting orientation to facilitate natural convection cooling.
- Maintain at least 50 mm clearance space above and below the unit for proper thermal dissipation.
- Check the input selector switch to ensure it matches your local AC line voltage (set to 230V for standard Bangladesh grid supply) prior to powering on.
Maintenance Tips:
- Routinely inspect screw terminal connections to ensure wires remain tightly clamped against machine vibration.
- Keep top and bottom ventilation grilles clean and free of accumulated lint or industrial dust.
- Check the green front LED regularly during routine panel audits to verify 24V DC output health.
Safety Instructions:
- Always disconnect main AC power before carrying out any wiring or mounting tasks.
- Installation must be performed by a qualified electrician or automation technician.
- Do not operate the unit in environments exceeding the IP20 rating without an appropriate enclosure.
