Electrical Commissioning

11.10.1
Before commissioning the device, check that all connections are made properly.
•
Connect the protective grounding terminal H (protective-conductor terminal) to the protective conductor
of the switch panel or of the control cabinet.
•
The secondary connections of interconnected current transformers must be short-circuited before you
disconnect the power supply that 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.
Initial Commissioning
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
values of alternating current and alternating voltage.
NOTE
i
i
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 the terminals needed for this purpose.
•
Connect the measuring lines that are connected to the measuring objects to the terminal blocks E
(Current) and F (Voltage).
•
Connect the process connections required for the measurements.
•
Connect a cable, for example, for the systems control, to the serial interface J (RS485 interface).
•
Connect a LAN cable for the PC or for other devices in the system to 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.
•
Switch on the supply voltage of the device.
NOTE
i i
A connection cable for the RS485 interface is not component of the delivery. This cable is available in the
specialized trade. The terminal connection of the RJ45 socket see chapter
faces.
NOTE
i i
The device does not have a power on/off switch. Switch the supply voltage on or off directly at the respec-
tive supply cable.
After an operating time of approximately 15 min, the device will stay within the tolerances specified in the
Technical data.
