Caution: During installation or maintenance procedures, wear a grounding wrist strap to avoid ESD damage to the
electronics of the appliance. Use a conductive wrist strap attached to a good earth ground or to the appliance. You can
attach it to the connector beside the ESD symbol on the back.
Follow basic electrical safety precautions to protect yourself from harm and the appliance from damage.
Be aware of the location of the emergency power off (EPO) switch, so that you can quickly remove power to the
appliance if an electrical accident occurs.
Remove all jewelry and other metal objects that might come into contact with power sources or wires before installing
or repairing the appliance. When you touch both a live power source or wire and ground, any metal objects can heat up
rapidly and may cause burns, set clothing on fire, or fuse the metal object to an exposed terminal.
Use a regulating, uninterruptible power supply (UPS) to protect the appliance from power surges and voltage spikes, and
to keep the appliance operating in case of power failure.
Never stack the appliance on top of any other server or electronic equipment.
All appliances are designed to be installed on power systems that use TN earthing. Do not install your device on a power
system that uses either TT or IT earthing.
Make sure that the appliance has a direct physical connection to the earth during normal use. When installing or repairing
an appliance, always make sure that the ground circuit is connected first and disconnected last.
Make sure that a fuse or circuit breaker no larger than 120 VAC, 15 A U.S. (240 VAC, 16 A international) is used on all
current-carrying conductors on the power system to which your appliances are connected.
Do not work alone when working with high voltage components.
Always disconnect the appliance from power before removing or installing any component. When disconnecting power,
first shut down the appliance, and then unplug the power cords of all the power supply units connected to the
appliance. As long as the power cord is plugged in, line voltages can be present in the power supply, even when the power
switch is OFF.
Do not use mats designed to decrease static electrical discharge as protection from electrical shock. Instead, use rubber
mats that have been specifically designed as electrical insulators.
Make sure that the power source can handle the appliance's maximum power consumption rating with no danger of an
overload. Always unplug any appliance before performing repairs or upgrades.
Do not overload the wiring in your server cabinet or on your server room rack.
During thunderstorms, or anticipated thunderstorms, avoid performing any hardware repairs or upgrades until the danger
of lightning has passed.
When you dispose of an old appliance or any components, follow any local and national laws on disposal of electronic
waste.
To prevent possible explosions, replace expired batteries with the same model or a manufacturer-recommended
substitute and follow the manufacturer’s instructions for battery replacement.
Never remove a power supply cover or any sealed part that has the following label:
