Bio-Rad PowerPac™ HC High-Current Power Supply - Manual (Page 5)

Safety
Caution/Warning
PowerPac power supplies use high output voltages that are electrically isolated
from earth ground through a protective impedance 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
0° and 40°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.
