Figure 6-4. Initial Access Procedure

6.Verify that both LEDs CR317 and CR318 on the Power Supply assembly (A4) are off. If either is lit after three minutes, there is a fault in the high voltage capacitor bleed-off path. Do not rely on an off condition as an indication that dangerous voltage no longer exists on the filter capacitors.

Warning

Do not rely on the power supply leds as an indication of the presence of high voltage. Always use a voltmeter to check for high voltage between TP307 and TP301, and between TP307 and TP304.

7.To confirm that high voltage has dissipated, set a DMM to the 1000V dc range, and take a reading with the common lead to TP307 and the high lead to TP301 on the Power Supply assembly. This is the +400V filter capacitor test point, and it should be at a safe level near zero.
