Getting Started; Important Guidelines - VWR International 250V Instruction Manual

Getting Started

Installing the 250V Power Supply
1. Check the label located near the AC inlet to ensure that the unit is compatible with locally
provided voltage.
2. Place the 250V Power Supply on a level laboratory bench. Keep the area around the power
supply clear to ensure proper ventilation of the unit.
3. For your safety: Position the unit properly such that the On-Off switch and the AC inlet
located on the rear of the unit are easily accessible.
4. Ensure the AC power switch is in the Off position.
5. Attach the power cord to the AC inlet. Use only properly grounded AC outlets and power
cords.
6. Connect the leads from the electrophoresis unit; insert the red lead (+) into the red output
jack, and the black lead (-) into the black output jack.

Important Guidelines

Introduction
The important guidelines for operating the 250V Power Supply are provided in this section. We
recommend that you carefully review these guidelines before operating the instrument.
Important
For best results, do NOT use the 250V Power Supply at its maximal electrical load limits.
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.
General Operating Instructions
Follow the instructions below to operate the 250V Power Supply.
•
Turn on the 250V Power Supply by toggling the power switch on the rear side of the
instrument. Upon start-up, the Display Screen appears on the screen.
