2.5.4 Safety circuits
The SIPLACE automatic placement system has a safety circuit which is monitored by the protec-
tive contactor combination K1. The protective contactor combination is contained in the power
supply unit (see item 14 in Fig. 2.5 - 4
).
WARNING
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 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 these au-
tomatic placement systems are handled incorrectly.
Always follow the applicable accident prevention and DIN regulations (particularly EN 60204,
part 1) and the applicable regulations in your own country.
The guard over the power supply must ONLY be opened by appropriately qualified and trained
personnel. 2
Protective contactor combination K1 monitors the following circuits:
EMERGENCY STOP circuit, safety circuits for the component trolleys or waffle-pack changer,
protective cover switches and the enable software signal
K1 is triggered if any of these functions fail. The main power voltage to the heavy current trans-
former that supplies the gantry axis motors, the star motor, the lifting tables and the used tape
cutter will be interrupted. The DP or Z axes for the placement heads are still supplied with
30VDC. The next diagram illustrates the various statuses of K1 and their effects on the axes and
the PCB conveyor components.

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
