6 Electrical Connection
Destruction of the measuring module due to short circuit
If a voltage-measurement device is connected to a measuring module in a 4-conductor utility grid, and a voltage
converter is not interconnected, there must not be a conductive connection between the neutral conductor and
grounding conductor. A conductive connection between the neutral conductor and the grounding conductor may
occur by inserting a jumper and then can result in a short circuit during commissioning. The measuring module is
destroyed when a short circuit occurs.
• If a voltage-measurement device without a voltage converter is connected to measuring module 1 in the 4-
conductor utility grid, ensure that the jumper between the terminals X200:4 and X200:5 has been removed.
• If a voltage-measurement device without a voltage converter is connected to measuring module 2 in the 4-
conductor utility grid, ensure that the jumper between the terminals X200:9 and X200:10 has been removed.
• If a voltage-measurement device without a voltage converter is connected to measuring module 3 in the 4-
conductor utility grid, ensure that the jumper between the terminals X200:14 and X200:15 has been
removed.

Requirements:
☐ The connected local utility grid must be a 4-conductor or a 3-conductor utility grid according to its grid type. If
another grid type is used, the connection of the current transformers must be coordinated with SMA Solar
Technology AG.
