* Do not connect the terminal. The terminal serves as the neutral point of the measuring system.
Requirements:
☐ The connected local utility grid must be a four-conductor or a three-conductor utility grid according to its grid
type(see Section 6.7.1 "Setup of the current and voltage measurement", page 26). If another grid type is used,
the connection of the current transformers must be coordinated with SMA Solar Technology AG.
☐ Only one grid type must be connected per measurement module.
☐ The cables must be protected in accordance with the locally applicable standards and directives.
☐ The current transformers used must have an accuracy class 1 or lower.
☐ The nominal output power of the current transformer must be at least 2.5 VA.
☐ The outputs of the current transformers are already grounded within the Fuel Save Controller. Therefore, the
outputs of the current transformers must not be grounded in any way outside of the Fuel Save Controller.
