Use as Prescribed
The equipment (device, module) must not be used for any other purposes than
those described in the Catalog and the Technical Description. If it is used together
with third-party devices and components, these must be recommended or ap-
proved by Siemens.

When electrical equipment is operated, hazardous voltages are inevitably present
in certain parts. If proper action is not taken, death, severe injury, or property dam-
age can result.
• The equipment must be grounded at the grounding terminal before any connec-
tions are made.
• All circuit components connected to the power supply can carry dangerous volt-
age.
• Hazardous voltages can be present in equipment even after the supply voltage
has been disconnected (capacitors can still be charged).
• Equipment with exposed current transformer circuits must not be operated.
Prior to disconnecting the equipment, ensure that the current transformer cir-
cuits are short-circuited.
• The limit values stated in the document must not be exceeded. This must also
be considered during testing and commissioning.
