Transformer Connections

High Voltage Wiring

The high voltage wiring section is located inside the SunTouch enclosure. The SunTouch system can be
connected either to 120 VAC or 240 VAC. The SunTouch system should be wired to receive continuous
power (connect directly to sub-panel). The maximum current rating is 820/410 mA at 120/240 VAC 60 Hz/50
Hz.
• For the AC power wire into the SunTouch Power Center from the main circuit breaker at the house, use
a three conductor cable. Follow manufactures instructions when installing and testing of ground fault
circuit breakers (GFCB) and interrupters (GFCI).
Connect input AC wires to the SunTouch Power Center transformer wires as follows:
120 VAC: Connect one wire to the Brown/White wires and one wire to the Blue/Black wires. One wire
must be connected to the grounding bar (see page 45).
240 VAC: Connect one wire to Black wire and one wire to Brown wire. The White/Blue wires are
connected together. One wire must be connected to the grounding bar (see page 45).
