The VW3AE2302 is a line-voltage voltmeter designed as a diagnostic accessory for Schneider Electric Altivar 61 Plus and Altivar 71 Plus floor-standing drives with separate air flows or compact enclosure versions. It monitors three-phase supply voltage across a 0 to 600 V AC range, intended for panel-mount integration within the drive enclosure to give operators a local read of incoming line voltage.
Installation constraint — 12-pulse supply
A specific condition of use applies: in installations with a 12-pulse supply configuration, only one voltmeter is built into the drive. This is a design limitation of the accessory, not a general restriction for 6-pulse or 18-pulse topologies.
