Warning Statements for Connecting to DC Power

These statements apply when connecting a Catalyst 2950G-24-EI-DC or Catalyst 2950ST-24 LRE 997 switch to DC power.

Warning	When installing the unit, always make the ground connection first and disconnect it last.
	Statement 42
Warning	Before connecting or disconnecting ground or power wires to the chassis, ensure that
	power is removed from the DC circuit. To ensure that all power is OFF, locate the circuit
	breaker on the panel board that services the DC circuit, switch the circuit breaker to the
	OFF position, and tape the switch handle of the circuit breaker in the OFF position.
	Statement 140
Warning	An exposed wire lead from a DC-input power source can conduct harmful levels of
	electricity. Be sure that no exposed portion of the DC-input power source wire extends
	from the terminal block plug. Statement 122
Caution	To make sure that the equipment is reliably connected to earth ground, follow the
	grounding procedure instructions, and use a UL-listed lug suitable for number-6 AWG
	wire and two number-10-32 ground-lug screws.
Caution	The switch must be installed with 5-A branch-circuit protection.
