The Multilin 3 Series Retrofit takes place in four general steps, as follows.
1. Select a replacement relay - see the summary tables and the specific order code
comparisons for the MII Family relays shown in this chapter. If you need to determine
your MII relay order code, refer to section 1.10 Finding your M and MII Family relay
order code.
2. Convert the existing settings file if applicable; MIF II, and MIV II file conversion is
currently supported for most models - see Chapter 2: Converting Settings Files.
3. Install the new 3 Series Retrofit - see Chapter 3: Installing the 3 Series Relay.
4. Wire the new 3 Series Retrofit - see Chapter 4: Electrical Installation.
3 Series relays have an IP54 rating, superior to that of the MII Family relays which have an
IP52 rating. In addition, vibration tests for 3 Series relays have been passed for both the 4-
screw mount (as used in the MII Family retrofit) and 8-screw mount (as used for new
installations).
