1.1.4. Maintenance Precautions
The following precautions should be taken when performing maintenance on RAYNOR doors.
Only certified personnel should perform maintenance on RAYNOR doors. Maintenance
performed by untrained technicians may result in injury and/or damage to equipment.
Service performed by unauthorized persons may void the RAYNOR door
warranty.
Use
only
RAYNOR Factory Direct replacement parts. All door parts are engineered
specifically for use within the door.
Return the door to the original factory condition when maintenance is complete. Take
extra care to ensure that all safety features are restored to their original condition.
Observe all electrical precautions.
1.1.5. Electrical Precautions
Electrical shock can be deadly! Take extreme care when performing
installation and maintenance tasks on the electrical components of the
door.
Follow the precautions listed below:
All electrical parts used to install or repair RAYNOR doors must be UL approved.
Lockout and tag electrical components in accordance with OSHA regulations and
approved electrical codes prior to performing maintenance. Lockout is required for
service or maintenance on all mechanical and electrical components, including
performance of the following tasks.
o Removal of covers, side guides, motor, limits and other protective devices
o Inspection of the door
o Inspection or maintenance of the Control Box
o Maintenance or repair of the opening commands
Disconnect the Uninterruptible Power Supply (UPS), if present, when performing
maintenance. Refer to the UPS Manual for information on disconnecting the UPS.
Take special care when addressing frequency inverter failure modes. The frequency inverter
stops the door when it senses voltage loss, phase differences and thermal overload. This stops
the door from further operation, but does not disconnect the power. Observe the following
precautions related to the frequency inverter.
Keep the frequency inverter cover closed at all times.
Disconnect the main power supply, wait 15 minutes and reconnect the power supply after
resolving frequency inverter failure modes.
Disconnect the power and proceed with lockout procedures to perform service after the
frequency inverter has stopped the door.
