    Immediately upon arrival, please check carefully that the shipment is complete and has not been dam- aged in transit. For missing parts or to report any kind of damage, please contact PEQLAB (see 'TECH- NICAL SERVICE AND ORDERING INFORMATION'). Please retain all packaging materials until the de- livery has been completely checked, since this will speed up the return of goods if required and reduce environmental impact.

    1. Check the label located near the AC inlet to ensure that the unit is compatible with locally pro- vided voltage. 2. Place the peqPOWER 250 Volt Power Supply on a level laboratory bench. Keep the area around the power supply clear to ensure proper ventilation of the unit.

  • Page 9: Important Guidelines

    We recommend that you carefully review these guidelines before operating the instrument. Important For best results, do NOT use the peqPOWER 250 Volt Power Supply at its maximum electrical load lim- its. Variations in buffer conditions can result in exceeding the power supply’s maximum voltage, current, or power output capacity and produce undesirable variations in electrophoretic separations.

  • Page 10: Operational Modes

    250 Volt Power Supply is provided below. We recommend reading the guidelines provided in this manual for best results before starting an operation. 1. Use the power switch on the rear side of the instrument to turn on the peqPOWER 250 Volt Power Supply. On Display Screen Constant Mode and Program Mode will appear.
  • Page 11 Basic Programming Protocol Instructions for operating the peqPOWER 250 Volt Power Supply in the Programming Mode are pro- vided in this section. The Programmable Mode allows you to vary levels in voltage (V), current (mA), and power (W) during specified periods of time as discrete changes (STEP) for up to 10 steps, depend- ing upon your electrophoresis needs.

  • Page 12: Choosing Limiting Parameter Settings

    Discontinuous buffer systems and, to a lesser extent, continuous systems increase resistance during the run. If you use the current limiting setting on the peqPOWER 250 Volt Power Supply, the voltage will increase as resistance increases to satisfy Ohm’s law (V=I*R). If no voltage limit is set and a local fault condition occurs, such as a poor connection, very high local resistance may cause the voltage to in- crease to the maximum capacity of the power supply.

  • Page 15: Repair And Maintenance

    Encountering Problems 1. Check the troubleshooting section. 2. Call Technical Service. 3. If the unit must be shipped back for repair, contact PEQLAB for a decontamination form and shipping instructions. Cleaning Device and output jacks must be always clean. Before using any cleaning or decontamination methods except those recommended by the manufacturer, check with the manufacturer that the proposed method will not damage the equipment.
  • Page 16 For additional fuses, contact PEQLAB’s Technical Service. To replace the fuse: 1. Turn off the main power switch at the rear of the peqPOWER 250 Volt Power Supply and de- tach the power cord from the rear of the peqPOWER 250 Volt Power Supply.

  • Page 17: Technical Support And Ordering Information

    Please have the unit’s serial number (located on the bottom panel of the instrument) available when call- ing. Should an item require return to PEQLAB for service, a decontamination form must be completed first by the user. Items sent without decontamination form will not be accepted.
