Lockout / Tagout - Epson RC180 Manual

Maintenance 1. Safety Precautions on Maintenance
■ Do not touch the Motor Driver modules, Switching Power Supply, and
Regeneration Module directly in the Controller. The metal resistance of these
can become very hot and may result in a burn. If you maintain them, examine
the surface temperatures and wear protective gloves if necessary.
■ Do not shock, shake, or drop any parts during maintenance. When the parts
related with data are shocked physically, they may be damaged and may also
cause data loss during data loading/saving.
■ Do not lose the screws removed at maintenance. When the screw is dropped
into the Controller, be sure to take it out. Leaving the screw in the Controller
may cause short circuit and may result in equipment damage to the parts and/or
robot system.
CAUTION
■ Make sure that the power rating (wattage) of a new Motor Driver module is
correct. Using a Motor Driver module with improper power rating (wattage) in
the Controller may cause improper function of the robot system and errors.
■ The serial number of the Manipulator that should be connected is indicated on
the Connection Check Label on the Controller. Connect the Controller and the
Manipulator correctly.
Manipulator may cause not only improper function of the robot system but also
serious safety problems.
Before performing maintenance on the Controller, all the data must be copied as a backup.
NOTE

The details of data backup/restore are described in the Maintenance 4. Backup and
Restore.
