Federal Communications Commission Advisory
This equipment has been tested and found to comply with the limits for a Class A digital device, pursu-
ant to part 15 of the FCC rules. These limits are designed to provide reasonable protection against
harmful interference when the equipment is operated in a commercial environment. This equipment
generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance
with the instruction manual, may cause harmful interference to radio communications. Operation of this

quired to correct the interference at their expense. Changes or modifications not expressly approved by
the party responsible for compliance could void the user’s authority to operate the equipment.
SAFETY INFORMATION
Avoiding Electrical Shock
The peqPOWER 250 Volt Power Supply produces up to 3 A or 250 voltage outputs which are electri-
cally isolated from ground to reduce the risk of electrical shock to the user. Follow the guidelines below
to ensure safe operation of the unit.
The peqPOWER 250 Volt Power Supply has been designed for use with electrophoresis cells with
shielded banana plugs thus minimizing any potential shock hazard to the user. Always use gel box sys-
tems that are compatible with the Power Supply, have been designed for your specific applications, and
are suitable for the voltage and current range of the Power Supply. PEQLAB recommends against the
use of gel box systems and / or power leads that have unshielded banana plugs.
To avoid electrical shock:
1.
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.
2.
WAIT at least 5 seconds after stopping a run before handling output leads or connected ap-
paratus.
3.
ALWAYS make sure that hands, work area, and instruments are clean and dry before mak-
ing any connections or operating the power supply.
4.
ONLY connect the power supply to a properly grounded AC outlet.
Avoiding Damage to the Instrument
1.
For proper ventilation, leave at least 10 cm of space behind the instrument, and at least
5 cm of space on each side.
2.
Do not operate the power supply in high humidity environments (> 95 %), or where conden-
sation may occur.
3.
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.
