• Find the switch to power off the cabinet. Read the posted instructions.
• Ensure that equipment can not be powered from another source or
controlled from a different circuit breaker or disconnecting switch.
• When a procedure requires that you power off the system:
— Lock the wall box-switch in the off position.

working with circuits that are powered. Disconnect power when
instructed to do so in the procedures.

otherwise instructed by a maintenance procedure.
• Disconnect all power before installing changes in machine circuits
unless otherwise instructed by a maintenance procedure.

extremely careful when measuring high voltages and when servicing
cards, panels, and boards while the system is powered on.
• Do not wear jewelry or other metal objects when working on the
equipment.
• When possible, work with one hand so that a circuit is not created.

install telephone wiring during an electrical storm.

specifically designed for wet conditions.
