The ground fault circuit interrupter must be a high-speed
type breaker of 30 mA (<0.1 s).
Procedure
Door 2 : electrical parts of the hydraulic compartment, backup
heater: XT5
（
3-phase
）
/XT4(1-phase)
For remote alarm:
1. Connect the cable to the appropriate terminals as shown on the
diagram.
2. Fix the cable with cable ties to the cable tie mountings to ensure
stress relief.
Procedure
1. Connect the cable to the appropriate terminals as shown in the
picture
2. Fix the cable with cable ties to the cable tie mountings to ensure

Procedures
1. Connect the valve cable to the appropriate terminals as shown
in the picture
2. Fix the cable with cable ties to the cable tie mountings to ensure

For 2-way valve SV2:
For 3-way value SV1
NOTE : Only a normal closing valve is available for this unit
NOTE : Wiring of the 3-way
valve is different for NC(normal
close) and NO (normal open).
Before wiring, read the Installation
& Owner's manual for the 3-way
valve carefully and install the valve
as showed in the picture. Make
sure to connect it to the correct
terminal numbers.

For solar energy kit
Type 2: Port provide the signal with 220V voltage. If the current of
load is <0.2A, load can connect to the port directly.
If the current of load is >=0.2A, the AC connector is required to
connected for the load.
