Read the installation instructions before using, installing or connecting the system to the power source.
Warning
This product relies on the building’s installation for short-circuit (overcurrent) protection. To reduce risk of
electric shock or fire, ensure that the protective device is rated not greater than:
Warning
This equipment must be grounded. To reduce the risk of electric shock, never defeat the ground conductor or
operate the equipment in the absence of a suitably installed ground conductor. Contact the appropriate electrical
inspection authority or an electrician if you are uncertain that suitable grounding is available.
Warning
Preventing Electrostatic Discharge Damage
Electronic components are sensitive to Electrostatic discharge (ESD). ESD precautions should always be
taken when handling electronic components. ESD damage occurs when electronic cards or components are
improperly handled and can result in complete or intermittent system failures. Use an antistatic strap whenever
handling electronic components. Touch the carriers edges only; never touch the boards or connector pins.
Always tighten the captive installation screws when present. These screws prevent accidental removal, provide
proper grounding for the system, and help ensure the bus connectors are properly seated.
Note
Follow these guidelines to prevent ESD damage:
• Always use an ESD wrist strap or ankle strap and ensure that it makes good skin contact.
• When handling a removed component, make sure the equipment end of you ESD wrist strap is attached
to an unfinished chassis surface of the device in which it is housed. Do not touch the printed circuit board,
and avoid contact between the printed circuit board and your clothing.
• Always place the component side up on an antistatic surface or in a static shielding bag. If you are
returning the item to the factory, immediately place it in a static shielding bag.
• Ensure that any plugin device are fully inserted and their captive installation screws are tightened. The
captive installation screws prevent accidental removal and provide proper grounding for the system.
For safety purposes, periodically check the resistance value of the antistatic strap. The measurement should
be between 1 and 10 megaohms (Mohms).
Note
Plant Wiring
When setting up the plant wiring and cabling at the site of the new system, consider the distance limitation
imposed by power cable lengths and connector compatibility.
