Safety
Caution/Warning
PowerPac power supplies use high output voltages that are electrically isolated from earth
ground to minimize the risk of electrical shock to the user. The following guidelines should
be observed and followed when using a PowerPac power supply.
PowerPac power supplies have passed test for operation at temperatures between 0º and
40º C, with relative humidity between 0 and 95% non-condensing. Operating the power
supply outside these conditions is not recommended by Bio-Rad and will void the
warranty.
1. To ensure adequate cooling of the power supply, be sure that there is at least 6 cm
clearance around the power supply. Do not block the fan vents at the rear of the unit.
2. Always connect the power supply to a 3-prong, grounded AC outlet, using the
3-prong AC power cord provided with the power supply.
3. Bio-Rad electrophoresis cells have molded two-prong plugs that are inserted into the
power supply's high voltage output jacks. These plugs have been EN 61010* certified
for safety compliance for use with PowerPac power supplies. Use of other plugs or
banana jacks is done at the user's own risk and is not recommended by Bio-Rad.
When inserting and removing the molded two-prong plug, always grasp the plug by the
molded support at the rear of the plug. Do not grasp the individual prong ends.
4. Do not operate the power supply in extreme humidity (>95%) or where condensation
can short the internal electrical circuits of the power supply.
5. When taking the power supply into a cold room, the unit can be operated
immediately. However, when removing the power supply from the cold room, let the
unit equilibrate to room temperature for a minimum of 2 hours before using it.
6. Never connect a high voltage output lead to earth ground. This defeats the floating
electrical isolation of the power supply and exposes the user to potentially lethal high
voltages.
Important
This instrument is intended for laboratory use only.
This product conforms to the class A standards for Electromagnetic Emissions, intended
for laboratory equipment applications. It is possible that emissions from this product may
interfere with some sensitive appliances when placed nearby or on the same circuit as
those appliances. The user should be aware of this potential and take appropriate
measures to avoid interference.
Bio-Rad's PowerPac power supplies are designed and certified to meet EN 61010* safety
standards. Certified products are safe to use when operated in accordance with the
instruction manual. This safety certification does not extend to electrophoresis cells or
accessories that are not EN 61010 certified, even when connected to this power supply.
This instrument should not be modified or altered in any way. Alteration of this instrument
will void the manufacturer's warranty, void the EN 61010 certification, and create a
potential safety hazard for the user.
Bio-Rad is not responsible for any injury or damage caused by the use of this instrument
for purposes other than those for which it is intended, or by modifications of the
instrument not performed by Bio-Rad or an authorized agent.
*EN 61010 is an internationally accepted electrical safety standard for laboratory instruments.
