Safety information

When transporting the devices and replacing components, note the following:
• Some of the devices and components are heavy or top heavy.
• Due to their weight, the devices must be handled with care by trained personnel.
Serious injury or even death and substantial material damage can occur if the devices are
not lifted or transported properly.
Note
When installing the cabinet unit, make sure that no foreign bodies – especially metallic
objects, such as drill swarf, wire end ferrules, or cable cut-offs – fall into the device. If
necessary, cover the ventilation slots.
Note
Safety regulations governing shock protection must be observed. See also EN 60204-1.
CAUTION
To ensure that the entire system functions properly, you are advised to use original
Siemens accessories.
Only original DRIVE-CLiQ cables may be used for wiring the DRIVE-CLiQ nodes.
Before commissioning, check the tightening torque of all the terminal screws.
Cable shields and unused cores/conductors of the power cables must be connected to PE
potential.
Non-observance can cause lethal shock voltages.
Note
On ungrounded systems and systems with a grounded phase conductor and a line voltage
> 600 V AC, measures must be taken on the line side to limit overvoltages to overvoltage
category II in accordance with IEC 60664-1.
