Before beginning the physical installation, ensure the power is completely disconnected. Safety standards for these units require specific pre-checks:
Test all door functions, including emergency disengagement and safety reversals. Disengagement Label:
For doors with impulse operation, briefly actuate the installation device; the door should move down, reverse against the floor or safety device, and then open fully to find its upper limit. Turn to OFF once the limits are learned. 3. Electrical & Troubleshooting
