2.4.5 Guard on the component table locations

DANGER 2

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

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

2.5 Residual voltages and discharge times in the

machine

If the EMERGENCY-STOP mushroom-head push-button is pressed or the placement system is

switched off, the 200 V link voltage for the gantry axes and the 100 V link voltage for the star axes

are discharged to harmless residual voltages in a very short time.

The voltages can be tapped off at test sockets X1 - X4 on the voltage measuring unit in the servo

unit. 2

WARNING 2

The placement system is supplied with 3 x 204 VAC (US version), 3 x 230 VAC, 3 x 380 VAC,

3 x 400 VAC or 3 x 415 VAC ± 5 %, 50/60 Hz main power voltage. 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 this automatic placement sys-

tem is handled incorrectly.

Æ Always follow the applicable accident prevention and DIN regulations (particularly DIN EN 60

204, part 1).

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

personnel.
