Safety Notes

DANGER
Hazard due to high voltage
Non-observance will lead to death or serious injury.
Work may only be carried out by trained personnel (see Preface) who are familiar with and observe the safety
requirements and precautions.
✧
Work may never be carried out if there is any hazardous voltage present.
✧
De-energize the device.
✧
Isolating device: Connect a suitable isolating device upstream to de-energize the device. The isolating
device must be installed near the device, it must be easily accessible to the user and it must be marked
as an isolating device for the device.
✧ Secure the supply voltage with an approved (UL/IEC) fuse: 1.6 A, type C.
✧ If a melting fuse is used, a suitable approved (UL/IEC) fuse holder has to be used.
NOTE
For electrical installations you have to observe and comply with the national and international provisions con-
cerning the installation of electric power installation and the low-voltage directive 2006/95/EG.
✧ Before commissioning the device, check that all connections are made properly.
✧
Connect the protective grounding terminal H
control cabinet.
✧ The secondary connections of interconnected current transformers must be short-circuited at these before
you disconnect the power supply leads to the device.
✧
Voltage measuring inputs: In the case of a direct connection and transformer connection, the device
has to be safeguarded with a listed 10 A backup fuse or a listed 10 A miniature circuit breaker. When
using voltage transformers, their secondary connections must never be short-circuited!
✧ Check the polarity and the phase assignment at the instrument transformers.
Siemens recommends leaving the device for a minimum of 2 hours in the operating room, before using it to
allow temperature equalization and to avoid dimness and condensation.
NOTE
Before you switch on the supply voltage, verify that the operational data match the rated data on the label and
the technical data according to chapter 12. This applies in particular to the supply voltage V
imum values of alternating current and alternating voltage.
