RISK OF DEATH BY ELECTRIC SHOCK
➠ Switch the placement system off at the main switch.
➠ Disconnect the placement system from the power supply.
➠ Wait approximately 1 minute until the residual voltages have dropped to a safe level (electro-
lytic capacitor C1).
➠ 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.

The transformer can be connected to the following main power supplies:
3 x 230 VAC for the "on-board electrical system" is drawn at terminals 1U5, 1V5 and 1W5. This is
used to supply the PC, the monitor and the lifting table motors.
