General Notes:
1. Rotary switch emulates drop down menu for "Pol Signal Sel" parameter setting in PCM600.
Switch position shown for default setting (Calculated Vo).
2. "Pol Signal Sel" parameter setting Calc Vo, and 59N-1 functions not applicable for open delta connected VTs.
3. Default labels for programmable pushbuttons 13 and 14. Pushbuttons are shown latched and toggle to emulate flip-flop
bus selection logic in PCM600 ACT (Application Configuration Tool). Relay defaults to Bus 1 selection when energized.

General Notes:
1. Style and code numbers for FT-1 switches provide black covers and handles, screw terminals and standard depth. Poles selection follows arrangement
shown in this drawing set. For custom designs, different selection options can be made by using FT-1 configurator at ft1switch.com
2. Refer to 620 series ANSI Installation Manual for relay and cutout dimensions ( Document ID: 1MAC457436-iB, Revision: A, Product version 2.0)
