2.6.6 Hand guard at the component trolley locations, SIPLACE HF

WARNING 2

All locations must be equipped with feeder modules in order to guarantee operational reliability. If

there are not enough feeder modules available, unassigned locations should be fitted with a

hand guard (dummy feeder module). When a waffle-pack tray holder is set up, the remaining

locations have to be protected again with a hand guard.

2.7 Residual voltages and discharge times in the

machine

If the emergency stop button is pressed or the placement system is switched off, the 250 VDC link

voltage for the gantry axes and the 145 VDC link voltage for the star axes are reduced to harmless

residual voltages in a very short time.

WARNING 2

The placement system is supplied with 3 x 208 VAC, 3 x 230 VAC, 3 x 380 VAC, 3 x 400 VAC or

3 x 415 VAC ± 5 %, 50/60 Hz mains voltage. This means that some parts of the system carry

potentially lethal voltages - even when switched off at the main power switch. Incorrect handling

of the placement system can therefore result in death or severe injury or considerable damage to

equipment.

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

204, part 1).

Æ The guards over the power supply unit and the axis unit must ONLY be opened by appropri-

ately qualified and trained personnel.
