2.8 Robot Modifications IMPORTANT: Do not remove the encoder cable connectors from their sockets. If they are removed, the calibration data will be lost, requiring factory recalibration of the robot. IMPORTANT: The base casting of the robot is aluminum and can easily be den- ted if bumped against a harder surface. Electrical Precautions DANGER: ELECTROCUTION RISK. AC power installation must be performed by a skilled and instructed person, as defined in this Guide. During installation, unauthorized third parties must be prevented from turning on power through the use of fail-safe lockout meas- ures. DANGER: ELECTROCUTION RISK.
Failing to ground robot-mounted equipment or tooling that uses hazardous voltages could lead to injury or death of a person touching the end-effector when an electrical fault condition exists. WARNING: ELECTROCUTION RISK. Appropriately sized Branch Circuit Protection and Lockout/Tagout Capability must be provided in accordance with the National Electrical Code and any local codes. Ensure compliance with all local and national safety and electrical codes for the installation and operation of the robot system. ! WARNING: UNEXPECTED ROBOT MOVEMENT. Make sure you select a 24 VDC power supply that meets the specifications given.
Using an underrated supply can cause system problems and prevent your equipment from operating correctly. Safety Requirements for Additional Equipment l Additional equipment used with the OMRON robots (end-effectors, conveyor belts, etc.) must not reduce the workcell safeguards l Emergency stop switches must be accessible at all times. l All components in the robot workcell must comply with all local and national safety requirements 2.8 Robot Modifications It is sometimes necessary to modify the robot in order to successfully integrate it into a work- cell. Unfortunately, many simple modifications can either cause a robot failure, or reduce the robot’s performance, reliability, or lifetime.
The following information is provided as a guideline to modifications. 18 Robot Safety Guide 18304-000 Rev. F
