Safety Instructions for Transporting the MTC2
Residual Volt ages at the In verters after Switching the MTC Off
Residual Voltages at the Inverters after Switching the MTC Off
After switching off the MTC2
▪ by pressing the EMERGENCY STOP button,
▪ by opening a protective door or
▪ via the SIPLACE station
it takes about 5 minutes before the intermediate-circuit voltages of the inverters have discharged down
to non-hazardous residual voltages.
When the MTC2 is switched off, the protective contactor combination is still supplied with 24 V AC from
the SIPLACE station.
Safety Instructions for Transporting the MTC2
▪ The MTC 2 should only be transported over any
significant distance using a suitable pallet jack or fork
lift truck.
▪ If the fork lift or pallet jack has adjustable forks, the
MTC2 must be lifted at the outer edge of the guide
rails.
▪ The forks should only be inserted into the guides from
the side on which tower 1 is located.

Protective Doors
Both towers have a protective door. When you open the
protective door, the tower is powered down. The following
error message appears on your screen:
Tower x: protective door not closedThe other
tower continues to work until it completes its cycle. Once
the protective door is closed, the cycle must be restarted.
CAUTION! Do not open the protective doors of
the MTC2 unless you are informed to do so on the screen
of the station computer or when the MTC2 has been
switched off.

Location of the EMERGENCY STOP button
Legend
1. EMERGENCY STOP button
The EMERGENCY STOP button is a self-latching
combination and designed with bypass protection
according to EN 418. This red, mushroom-shaped button
remains depressed when you press it.
When you press the EMERGENCY STOP button, the
entire line, with SIPLACE station and MTC2, is
immediately stopped. Placement is interrupted and, once
the machine is in working order again, can be resumed or
canceled. Watch out for any incompletely assembled
printed circuit boards.
Pressing the EMERGENCY STOP button opens the two
switching contacts of the safety circuits; the relevant
safety combination is triggered. The intermediate-circuit
voltages (500 V) for the inverters are disconnected. Both
the lifting and feed axes are deactivated while the logic
circuitry of the inverters continues to be supplied with 24
V DC. The following error message appears on your
screen: EMERGENCY STOP operated will be shown on
the screen.
