2.5.5 Hand guard on the component table locations

WARNING

All locations must be equipped with feeders in order to guarantee operational reliability. If there

are not enough feeders available, a hand guard ("dummy feeder") must be fitted in place of the

feeder. 2

2.6 Residual voltages in the servo unit and discharge

times

When the EMERGENCY STOP button is pressed or the placement system is switched off, the

electrolytic capacitors quickly discharge to safe residual voltage levels via switched resistors on

the discharge board (00308443-xx).

The voltages can be tapped off at test sockets 001 - 009 on the voltmeter unit in the servo unit. 2

DANGER Automatic placement systems from the SIPLACE family are

powered with 3 x 400 VAC (3 x 208 VAC for the U.S.A. version) ± 5 %, 50/60 Hz main power volt-

age. This means that some parts of the system carry potentially lethal voltages - even when

switched off at the main power switch.

Death, serious injury or considerable damage may result if these automatic placement systems

are handled incorrectly. Always follow the applicable accident prevention and DIN regulations

(particularly EN 60204, part 1).

The guard over the servo unit must ONLY be opened by appropriately qualified and trained per-

sonnel. 2

CAUTION

To avoid losing data, evaluate the following criteria before switching off your automatic placement

system (apart from in emergencies):

– Has the placement system finished transmitting machine, setup and panel data?

– Has the placement system finished processing the PCB?

– Has the placement system completed the run-up phase?

– Has the Windows XP operating system been shut down correctly? 2
