Apply lockout/tagout (LOTO) devices to isolate equipment from all potentially hazardous energy. Applying LOTO devices ensures that equipment is locked out when performing any service or maintenance activities.

All authorized personnel who perform maintenance or service work are responsible for following the LOTO procedure. Supervisors are responsible for ensuring that their teams understand and comply with the LOTO procedure.
Note All personnel must receive training in the proper application and removal of LOTO devices.
Note LOTO procedures apply to all forms of energy, including electrical and pneumatic energy (if applicable).

Record all lockout/tagout activities in the LOTO logbook. Include the date, time, equipment involved, and personnel responsible.

  1. To prepare the ETX-1630x for shutdown, complete the following steps:
    1. Identify all energy sources associated with the machine or piece of equipment, including electrical and pneumatic energy sources.
    2. Review all available documentation, including electrical diagrams, piping schematics, and any equipment-specific lockout procedures.
    3. Notify all affected personnel that a lockout is required and why.
  2. Power off the ETX-1630x.
    Refer to Powering the ETX-1630x Off for more information.
  3. To isolate the equipment from energy sources, locate and operate the isolating devices.
  4. Power off or disconnect the feeder breaker.
  5. Apply a lockout device to each energy-isolating device.
    Applying the lockout device ensures nobody can operate the energy-isolating device.
  6. Apply the ABB lockout device (part number ABB S2C-LOTO-M) to the breaker of the ETX-1630x circuit breaker.
    1. Turn the breaker to the off position.
    2. Screw the lockout device to the breaker handle.
    3. Apply the lock through the center of the device, covering the screw.
  7. Place a clearly visible tag on each lockout device with the following information:
    • Who is responsible for the lockout
    • Date
    • Reason for the lockout
    Note Ensure that the tags follow all local regulations. Most facilities require a two-person team to apply and verify tags.
  8. Release or block any stored energy.
    For example, bleed the pneumatic lines.
  9. Test for zero energy by verifying that all energy sources are isolated.
    The status light on the ETX-1630x is off when all energy sources are isolated.
  10. Re-verify that all energy sources are isolated and that all stored energy has been dissipated.
Perform the necessary maintenance or service while ensuring that the lockout remains in place. Continue to monitor the work environment for any unsafe conditions.
