Instructions should be read by experienced individuals before operating the instruments. Any improper usage of the instruments may cause damage. Please refer to the safety notice included with this equipment. The instruments shall not be modified or altered in any way.
EPS-300 X A-3. Safety Notice EPS-300 X power supply uses high voltage output. To minimize the risk of electrical shock to the user the following guidelines should be observed and followed when using EPS-300 X power supply. Always read the product manual before operating the unit. EPS-300 X power supply shall be operated at temperature between 0℃ and 40℃, with relative humidity between 10% and 90% non-condensing.
EPS-300 X B. Introduction EPS-300 X power supply is compact, space saving and light weight in design. It can be used with many electrophoresis applications, such as running standard PAGE gels, multiple PAGE mini gels, horizontal/vertical agarose gels, semidry transfer and mini-gel tank transfer. The LED display reports power supply status. Parameters are set by pressing UP/DOWN arrow buttons in combination with a MODE button. Four pairs of output jacks accept 4 mm plugs, which operate in parallel.

Setup and Operation of the EPS-300 X Power Supply C-2-1. Unpacking Unwrap all packages carefully and compare contents with the packing list, ensure the arrival of all the items. If any part is missing, contact your local C.B.S. Scientific representative. Inspect all the components for damage that may have occurred while the unit was in transit.
EPS-300 X Caution: If you are in the middle of a run and wish to connect or disconnect the leads, always turn the power off (RUN button) and wait for the display to read “OFF” 1. Connect the main power cord: Connect the main power cord to the power cord receptacle on the rear panel and to a suitable grounded AC power outlet. 2. Connect the HV power leads: Connect the apparatus to the power supply by plugging the lead connectors into one pair of the recessed output jacks.
EPS-300 X run, a ~3 second beep sounds and the display changes to “OFF”. To reset the power supply press any button except the RUN button. PFD: The Power Failure Detection feature will save the time, voltage and current settings in the event of a power outage and automatically continue the run when the power is restored. To alert the user that a power failure occurred during the run, the error message “E6” flashes at the end of the run instead of the usual “OFF” message.
EPS-300 X D. Troubleshooting D-1. Basic troubleshooting Caution: Wait 10 seconds while disconnecting the main AC input power cord to allow voltage discharge within the power supply when restarting. Symptom Action and possible causes 1. Check main power source Fan is not spinning LED & Display do not light up Front panel power on indicator off 2. Check the fuse, replace a new same configuration fuse if necessary and try again 3. Check if power switch malfunction 4. Contact your local C.B.S.
EPS-300 X D-2. Error codes The EPS-300 X power supply has built-in error messages to help troubleshoot problems with the electrical circuit. The error codes and possible corrective actions are listed below: Error Explanation Code Possible Solution No load detected 1. Check all the connections The voltage leads to the 2. Verify that buffer volumes are sufficient to electrophoresis cell are not E1 contact all electrode wires and that buffer plugged. is contacting both surfaces of the gel.
EPS-300 X 1. Check for any short circuit or evidence E7 Short Circuit Load current exceeded 500 mA of electrical arching. 2. Buffer concentration is too high. 3. Press any button* to clear the error code. *Press any button, except the RUN button, to clear the error message. D-3. Replacing the fuses 1. Unplug the power cord from the power supply. 2. Locate the fuse compartment on the rear panel. 3. Use a screwdriver to pry out the fuse compartment. There are two fuses in the compartment.
EPS-300 X E. Care and Maintenance Turn the main power switch off and unplug the power cord before cleaning. Use a soft cloth dampened with water or a mild cleaning solution to clean the cabinet and display. If spilled liquids contact the circuit boards, unplug the power supply and allow to dry completely.
