DETAIL / 01

Function-based panel design

The panel is built around the protected equipment and its protection scheme. Differential, backup or automatic-transfer functions should be requested as applicable, rather than assumed to be present in every panel.

DETAIL / 02

Measurement and control

Measurement inputs, breaker commands and status signals are arranged with the selected protection devices and control circuits.

DETAIL / 03

Communication interfaces

An isolated RS485 interface is described for system communications. Device protocol, point list and compatibility with the supervisory system must be confirmed.

DETAIL / 04

Local operation and indication

The panel layout coordinates the selected devices, operating controls and indications. Display language and operator requirements should be specified for the destination installation.
