Field Installation Guidelines
Follow these technical procedures during panel installation and enclosure mounting:
- Electrical Isolation: De-energize and lock out incoming supply power. Verify zero voltage using a calibrated multimeter prior to touching terminal connections.
- Electrostatic Discharge Handling: Wear a grounded ESD wrist strap when unboxing and positioning the unit to prevent static damage to internal logic circuits.
- Mechanical Mounting: Snap the module securely onto standard DIN-rail mounting tracks inside the cabinet, verifying that spring clips lock fully into place.
