29. y grounded electrical outlet 4 Push the power button on the front panel To power off the instrument push the front panel power button WARNING To satisfy safety requirements always use load wires heavy enough not to overheat when carrying the maximum IN short circuit output current of the power supply If there is more than one load then every pair of load wires must be capable of safely carrying the full rated current of the power supply What to Do if the Power Supply Does Not Turn On To solve problems you might encounter when turning on the instrument follow these steps 1 Verify that there is AC power to the power supply First check that the AC power cord is firmly plugged into the power connector on the rear panel of the power supply You should also make sure that the AC power source you plugged the power supply into is energized Then check that the power supply is turned on Verify the power line voltage settings Check that the line voltage selector switch on the bottom of the instrument is set to the proper value for your country 110 Vac or 220 Vac Change the voltage setting if it is not correct NOTE Under certain circumstances powering the instrument from a mains voltage for which it is not configured can cause the mains fuse to open 3 Verify that the correct power line fuse is installed 4 If the fuse is damaged replace the fuse for your power supply If you set the line selection t
