Unit with VDIS

DANGER
HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH You must use the VDIS unit to detect and indicate the presence or absence of operating voltage. You must not use the VDIS unit to distinguish between voltage not present (that is U < 10% of nominal voltage) and dead circuit state (that is U = 0 V). Failure to follow these instructions will result in death or serious injury.

The VDIS unit is an integrated, self-powered voltage detecting and indicating system.

The VDIS unit is integrated into Schneider Electric high-voltage equipment, flush mountable, and designed according to IEC 62271-213: 2021 standard. Fitted with a three LED display, it detects the operating voltage presence/absence on the main circuit.

The VDIS unit receives the information through a capacitive sensor installed inside the high-voltage equipment.

The range of VDIS units consists of three versions:

• No Voltage Output (VO): voltage presence detection and interface to phase concordance units.

• VO FlairDIN: voltage presence detection, interface to phase concordance units and voltage output cable connection to fault passage indicators.
  The VO FlairDIN cable is connected to the input of the Flair 2xD or VD23 ranges.

• VO T300: voltage presence detection, interface to phase concordance units and voltage output cable connection to SC150 for voltage measurement. The VO T300 cable is connected to the VDIS voltage adapter, which is linked to the Easergy SC150 module of T300 via an Ethernet cable.

The VDIS unit has three main functions:

1. Visual indication of MV operating voltage presence/absence.

2. Phase concordance output.

3. Voltage Output (VDIS-VO only).
