Lockout/Tagout (LOTO) Requirements
Follow OSHA Lockout/Tagout requirements (USA) or local Lockout/Tagout requirements by ensuring
you are in total control of the AC power plug at all times. This will protect service personnel from injuries
caused by unexpected energizing or start-up of equipment during service, repair, or maintenance.
To apply Lockout/Tagout (LOTO):
1.) Plan and prepare for shutdown.
2.) Shutdown the equipment.
3.) Isolate the equipment.
4.) Apply Lockout/Tagout Devices.
5.) Control all stored and residual energy.
6.) Verify isolation.
All potentially hazardous stored or residual energy is relieved.
ENERGY CONTROL AND POWER LOCKOUT FOR VIVID™ S60N/VIVID™ S70N.
WHEN SERVICING PARTS OF THE SYSTEM WHERE THERE IS EXPOSURE TO VOLTAGE
GREATER THAN 30 VOLTS:
1.) TURN OFF THE BREAKER.
2.) UNPLUG THE SYSTEM.
3.) MAINTAIN CONTROL OF THE SYSTEM POWER PLUG.
4.) WAIT FOR AT LEAST 20 SECONDS FOR CAPACITORS TO DISCHARGE AS THERE ARE NO
TEST POINTS TO VERIFY ISOLATION. THE AMBER LIGHT ON THE OP PANEL ON/OFF BUTTON
WILL TURN OFF.
BEWARE THAT THE MAIN POWER SUPPLY AND BACK END PROCESSOR MAY BE ENERGIZED
EVEN IF THE POWER IS TURNED OFF WHEN THE CORD IS STILL PLUGGED INTO THE AC
OUTLET.
