High Voltage Wiring
The high voltage wiring section is located inside the SunTouch
®
Control System enclosure. The SunTouch
Control System can be connected either to 120 VAC or 240 VAC. The SunTouch Control 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 Control System 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 Control System 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.
•
240 VAC: Connect one wire to Black wire and one wire to Brown wire. The White/Blue wires are
connected together.
