NOTE
The ground fault circuit interrupter must be a high-speed
type breaker of 30 mA (<0.1 s).
5.9.3.2 Connection for other components
■ Electrical parts of the hydraulic compartment: The XT4/XT5 contains
terminals for solar energy, remote alarm, 2-way valve, 3-way valve,
pump, booster heater and external heating source.
The parts wiring is illustrated below:
■
Equipment must be grounded.
All high-voltage external load, if it is metal or a grounded
port, must be grounded.
■ All external load current is needed less than 0.2A,
if the single load current is greater than 0.2A,
the load must be controlled through AC contactor.
■
"STV1" "STV2", "A1" "A2", "R1" "R1" and "DTF1" "DTF2"
wiring terminal ports provide only the switch signal.
TBH electric heating power is less than 3000W.
