		connecting or disconnecting any high voltage component, open and
		padlock open the disconnect switch which provides power to that
		component.
		Failure to follow this precaution can result in death, serious injury,
		or equipment damage.
		WARNING

	module is compatible with the Hot Standby system. Be sure that you use the
	correct terminator.
