Field Installation Manual
Connection Type # 1
Use this instruction
If 200 Amp circuit breaker is available in customer Main Breaker Panel.
S-50 is designed for use with Main Breaker Panel Three Phase 208V AC WYE/Delta
Connection, up to 1600 Ampere.
S-50 unit should be mounted with four appropriate sized fasteners before connect to
Main Breaker Panel.
1.1 Power Connections
1.11 Using panel key open the door of S-50 exposing connections.
1.12 Locate Earth Terminal in S-50, connect the earth wire to S-50 Earth Terminal. Connect the other
side of earth wire to main breaker panel ground rod. Ensure all mechanical connections are secure
and making full contact.
1.13 Locate existing 3 Pole 200 Amp Circuit Breaker in the Main Breaker Panel.
Connect the wire L1 to Phase 1 of 200 Amp circuit breaker.
(b) Connect the wire L2 to Phase 2 of 200 Amp circuit breaker.
(C) Connect the wire L3 to Phase 3 of 200 Amp circuit breaker.
1.14 Qualified Representative must inspect size of cable minimum 3/0 AWG.
1.15 Connect power cables to BUS BAR of S-50.
1.2 Current Sensor Connections
1.21 Open one side of Split CT (Current Sensor). Clip the CT on the wire L3 before main Circuit
Breaker Panel.
1.22 Locate Terminal Block T2 (S1-S2) in S-50.
1.23 Qualified Representative line side of Main Panel should connect the wires 18-22 AWG from external
CT to T2 (S1-S2), preferably twisted together.
1.24 Firmly secure current sensor to line side (L3) of main circuit breaker.
