Safety Considerations
Read and understand this manual completely before attempting to set up or use
this instrument.
This equipment has been designed and tested to conform to CSA1010 safety standards, as
applicable to laboratory instrumentation. This applies only to the EPS-3000P-II(V) when used
as specied in the documentation, in its intended applications, with CBS Scientic approved
electrophoresis apparatus only. Usage in any other manner may not provide similar performance
or safety protection.
This equipment is provided with a 3-conductor, grounded AC line cord. The protective earth
ground is necessary for safe operation. Do not use any other AC line cord with this instrument.
The EPS-3000P-II(V) is a high voltage power supply capable of generating dangerous levels
of voltage and current during operation. Exercise caution when working around and with the
electrical connections of this equipment. Always check electrical connectors, wires, and associated
apparatus for any signs of wear or damage before using with this equipment. Be sure to use only
electrophoresis equipment that is suitably rated for the voltage and current capabilities of the EPS3000P-II(V) power supply.
The output of the EPS-3000P-II(V) power supply is intended for connection to electrically isolated
electrophoresis apparatus only. Use only with electrically isolated electrophoresis apparatus with
minimum isolation of 3000V. Do not connect any terminal of the EPS-3000P-II(V) output to earth
ground. This may impair the safety protection provided by the equipment, or cause equipment
damage.
The high voltage output of the EPS-3000P-II(V) power supply takes some amount of time to
decay when unloaded or lightly loaded. Wait a minimum of 60 seconds after stopping a run
before touching the power supply leads.
This equipment has a protective ground leakage current of 0.5mA at 120VAC, and 1mA
at 230VAC. While signicantly below the 3.5mA limitation for laboratory instrumentation,
some applications and locations require a leakage current below 0.5mA. Check the specic
requirements of your application before using this equipment.
This equipment is for indoor use only.

Introduction
Thank you for selecting a CBS Scientic EPS-3000P-II(V) Electrophoresis power supply. This
manual describes the operation of the EPS-3000P-II(V). The power supply that you have purchased
is the most productive and easy-to-use unit available anywhere. This manual should answer any
questions that might arise in operating your power supply; however, don’t hesitate to call our CBS
Scientic Technical Support at 1-800-756-5737 or email us at TechnicalService@cbssci.com if you
need any assistance.
The EPS-3000P-II(V) power supply is designed to provide constant voltage, current, power, or
temperature in both Manual and Programmed modes of operation commonly used in electrophoresis
applications. One to four sets of electrophoresis cells can be connected in parallel and run
simultaneously. The EPS-3000P-II(V) can deliver up to 400W of total output power. When operating
in any constant mode, the power supply automatically limits the other parameters to either the power
supply maximum, or a lower limit if set by the user. If any non-constant limit is reached, the power
supply will automatically switch control modes, controlling the limit parameter. Note:
crossover and control for temperature when the unit is in the Constant Current, Constant Voltage, or
Constant Power mode. The only time the unit will control for temperature as an upper limit is when the
unit is in the Constant Temperature mode (See Constant Temperature Operations section for details).
In this way, the EPS-3000P-II(V) protects your electrophoresis cells from damaging over power
conditions. The EPS-3000P-II(V) power supply also provides for timed and volt-hour operation in all
control modes, and allows an automatic completion in the event of a power loss if enabled.

Unpacking the Power Supply
When unpacking your EPS-3000P-II(V) power supply, be sure you have received the following items.
. •EPS-3000P-II(V) unit
. •AC line cord(s)
. •This manual
Inspect your equipment and packaging material for signs of damage. Damage to the shipping
container may indicate rough handling which could cause internal damage to the power supply. If you
suspect shipping damage to the power supply, contact your carrier for instructions on ling a claim. If
you are missing any of the above items, contact your supplier for instructions.
