Notes:
1. See Protection Device description in this section.
2. Metal conduit or shielded cable should be used. Connect conduits so
the use of a Reactor or RC Device does not interrupt EMI/RFI shielding.
3. Use the same gauge wire for Earth as used for L1, L2, L3 connections.
4. Reference EMC wiring in control manual (MN1220 Section 8).

Important:
Be sure to connect the proper voltage for X3
Logic Power input. Look at the last digit of the
identification number to determine voltage:
BPSxxx0 = 230VAC – 1 phase
BPSxxx1 = 115VAC – 1 phase
