Retrofit Existing Multilin MII Family Devices

Traditionally, retrofitting or upgrading an existing relay has been a challenging and time consuming task often requiring re-engineering, panel modifications and
re-wiring. Similar features and form factor of some models of MII family devices allow users to replace their existing relays with 3 Series relays with enhanced
protection and control features and advanced communications.

The SR3 Enervista Setup software allows users to create new setting files based on existing MIFII and MIVII setting files and can be uploaded to a 339 relay with
a compatible model number. Retrofit is smooth and simplified with minor wiring or switchgear modifications.
