American Power Conversion AIS 5000 manual User Safety, Disconnect all sources of AC and DC power

User Safety

	WARNING!
	This UPS contains hazardous AC and DC voltages. Only qualified electricians
	should connect the UPS, AC line and external batteries, and must be familiar with
	batteries and battery installation.
	Before installing, maintaining or servicing the UPS, shut off the UPS and
	disconnect all sources of AC and DC power.
	As the UPS has no built-in disconnection devices to switch off external AC and DC
	input power, ensure that disconnection devices are available as separate parts in
	connection with the installation!
	AC and/or DC voltage will always involve a potential risk of AC voltage at UPS
	output generated from either batteries or utility. To avoid equipment damage or
	personal injury, always assume that there may be voltage at UPS output.
	This system is equipped with an auto-start function. If activated, the system may
	start without warning. Refer to the “Programming” section for information on de-
	activation.
	The installer must provide each external disconnecting device for this UPS system
	with labels with the following text:
	“Isolate the Uninterruptible Power Supply (UPS) as instructed in this guide before
	working on circuit”
	WARNING!
	TEST BEFORE YOU TOUCH!
	To reduce the risk of fire or electric shocks, install the UPS and external batteries
	in a temperature and humidity controlled indoor area, free of conductive
	contaminants.
	WARNING!
	UPS batteries are high-current sources. Shorting battery terminals, DC terminals
	or DC busbars can cause severe arcing, equipment damage and injury. A short
	circuit can cause a battery to explode. Always wear protective clothing and eye
	protection and use insulated tools when working on batteries.
	CAUTION!
	This unit contains components sensitive to electrostatic discharge (ESD). If you do not
Caution	follow the ESD procedures, you may cause severe damage to electronic components.
