6. Important Safety Instructions
6.1 General Safety Instructions
• Read all of these instructions and save them for future reference.
• Follow all warnings and instructions marked on the device.
• Do not place the device on any unstable surface. If the device falls, serious damage will result.
• Do not use the device near water.
• Do not place the device near or over radiators or heat registers.
• The device cabinet is provided with slots and openings to allow for adequate ventilation. To ensure reliable operation
and protect against overheating, these openings should never be blocked or covered.
• The device should never be placed on a soft surface such as a bed, sofa or rug. Doing so will block the device’s
ventilation openings. Moreover, the device should not be placed in a built-in enclosure unless adequate ventilation has
been provided.
• Never spill liquid of any type on the device.
• Unplug the device from the wall outlet before cleaning. Use a damp cloth for cleaning. Do not use liquid or aerosol
cleaners.
• The device should be operated from the power source indicated on the marking label. If uncertain of the power
available, consult your dealer or local power company.
• The device is designed for IT power distribution systems up to 230V phase-to-phase voltage.
• As an added safety feature, the device is equipped with a 3-wire grounding type plug. If unable to insert the plug into
the outlet, contact an electrician to replace the obsolete outlet. Do not attempt to plug into a two-prong ungrounded
outlet. Always follow local/national wiring codes.
• Do not allow anything to rest on the power cord or cables. Route the power cord and cables to avoid them being
stepped on or tripped over.
• If an extension cord is used with this device, ensure the total ampere ratings of all products used on the extension
cord do not exceed its rated ampere rating. Also ensure all products plugged into the wall outlet do not exceed a total
of 15 amperes.
•Considerationshouldbegiventotheconnectionofequipmentandthesupplycircuit,aswellaswhate󰀨ect
overloading the supply circuit might have on overcurrent protection and supply wiring.
• To help protect the system from unexpected transient increases and decreases in electrical power, use a Tripp Lite
Surge Protector, Line Conditioner, or Uninterruptible Power Supply (UPS).
• Position system cables and power cables carefully so nothing rests on any cables.
• When connecting or disconnecting power to hot pluggable power supplies, observe the following guidelines:
– Install the power supply before connecting the power cable to the power supply.
– Unplug the power cable before removing the power supply.
– If the system has multiple sources of power, disconnect power from the system by unplugging all power cables from
the power supplies.
• Never push objects of any kind into or through cabinet slots. They may touch dangerous voltage points or short out
partsresultinginariskofreorelectricalshock.
•Donotattempttoservicethedevice;referallservicingtoqualiedservicepersonnel.
