to correct the interference at their own expense.
Safety Guidelines
z Follow these guidelines to ensure general safety:
z Keep the chassis area clear and dust‐free before, during and after installation.
z Do not wear loose clothing or jewelry that could get caught in the chassis. Fasten your tie or scarf and
roll up your sleeves.
z Wear safety glasses/goggles if you are working under any conditions that might be hazardous to your
eyes.
z Do not perform any action that creates a potential hazard to people or makes the equipment unsafe.
z Disconnect all power by turning off the power and unplugging the power cord before installing or
removing a chassis or working near power supplies
z Do not work alone if potentially hazardous conditions exist.
z Never assume that power is disconnected from a circuit; always check the circuit.
LITHIUM BATTERY CAUTION:
Risk of explosion could occur if battery is replaced by an incorrect type. Please dispose of used batteries
according to the recycling instructions of your country.
Operating Safety
z Electrical equipment generates heat. Ambient air temperature may not be adequate to cool
equipment to acceptable operating temperatures without adequate circulation. Be sure that the
room in which you choose to operate your system has adequate air circulation.
z Ensure that the chassis cover is secure. The chassis design allows cooling air to circulate effectively.
An open chassis permits air leaks, which may interrupt and redirect the flow of cooling air from
internal components.
Electrostatic discharge (ESD) can damage equipment and impair electrical circuitry. ESD damage occurs
when electronic components are improperly handled and can result in complete or intermittent failures.
Be sure to follow ESD‐prevention procedures when removing and replacing components to avoid these
problems.
z Wear an ESD‐preventive wrist strap, ensuring that it makes good skin contact. If no wrist strap is
available, ground yourself by touching the metal part of the chassis.
z Periodically check the resistance value of the antistatic strap, which should be between 1 and 10
megohms (Mohms).
z Installation only by a trained electrician or only by an electrically trained person who knows all the
applied or related installation and device specifications..
z Do not carry the handle of power supplies when moving to other place.
