2.0 Safety Information
2.1 Avoiding Electrical Shock
The Labnet Enduro™ 250V and 300V Power Supplies produces up to 250 or 300 voltage outputs
respectively which, are electrically isolated from ground to reduce the risk of electrical shock to the user.
Please follow the guidelines below, and read this manual in its entirety to ensure safe operation of the
units described herein.
The Labnet Enduro Power Supplies have been designed for use with electrophoresis gel box systems
with shielded banana plugs thus minimizing any potential shock hazard to the user. Always use gel box
systems that are compatible with the Power Supply, have been designed for your specific applications,
and are suitable for the voltage, current, and power range of the Power Supply. To prevent accidental
electric shocks to the user, always use gel box systems that have safety lids. Labnet recommends against
the use of gel box systems and/or power leads that have unshielded banana plugs, thus minimizing any
potential shock hazard to the user.
To avoid electrical shock:
NEVER connect or disconnect wire leads from the power jacks when the red indicator light at the
Start/Stop key is on or when “RUNNING” is displayed on the screen.
WAIT at least 5 seconds after stopping a run before handling output leads or connected apparatus.
ALWAYS make sure that hands, work area, and instruments are clean and dry before making any
connections or operating the power supply.
ONLY connect the power supply to a properly grounded AC outlet.
2.2 Avoiding Damage to the Instrument
For proper ventilation, leave at least 10 cm of space behind the instrument, and at least 5 cm of space
on each side.
Do not operate the power supply in high humidity environments (>95%), or where condensation may occur.
To avoid condensation after operating the power supply in a cold room, wrap the unit in a plastic bag,
and allow at least 2 hours for the unit to equilibrate to room temperature before removing the bag
and operating the unit.
NOTE: If the unit is used in a manner not specified by the manufacturer, the protection provided
by the equipment may be impaired.
This symbol is used on the Labnet Enduro Power Supplies to indicate an area where a potential
