PLEASE NOTE: Remember to replace the perspex safety panels over rectifiers V1 and V7
when the measurements are complete. 3
RISK OF DEATH BY ELECTRIC SHOCK 3
Æ Switch the placement system off at the main switch.
Æ Disconnect the placement system from the power supply.
Æ Wait approximately 1 minute until the residual voltages have dropped to a safe level (electro-
lytic capacitor C1).
Æ Attach the perspex safety panel and fix in place with the M5 fillister head screws.
CAUTION
Do not overtighten the fillister head screws. The perspex panel might break. 3
