Initial Commissioning

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.
After you have inserted the battery, assembled the device and connected the supply voltage lines, you can start
the device for the first time. Proceed as follows:
✧
Check that the operational data match the rated data on the label and the technical data of the device (see
chapter 13). This applies in particular to the supply voltage and to the maximum values of alternating
current and alternating voltage.
NOTE
The wiring of the terminals described in the following depends on the type of measurement and analysis of the
measuring result. You only have to wire terminals needed for this purpose
✧
On the terminal side of the device connect the measuring lines linked with the measurement objects at the
terminal blocks E (current) and F (voltage); chapter 6 describes interfaces, connection principles, and
examples of connection possibilities.
✧
On the terminal side of the device, connect the process connections required for the measurements.
✧
For example, connect a cable to the systems control on the terminal side of the device at terminal block J
(for devices with RS485 interface).
✧
On the top side of the device, connect the network cable to the PC at the RJ45 socket Z (Ethernet).
✧
Close the door of the control cabinet to prevent touching live parts.
✧ Switch on the connected peripheral devices (PC, measuring device or modules) for measurand analysis.
