The water heater is connected to the AC mains with a voltage of 220-240V~ by a three-core
copper electric cable with a minimum cross-section of the core and a circuit breaker in the power
board according to the table below:
Models name
T-WI3-P10*
T-WI6-P10
It is forbidden to use the electrical plug and socket when connecting the water heater to the
electrical network, except for the T-WI3-P10 series.
The water heater must be permanently connected to a 220-240V~, alternating current power
supply with a mandatory connection to a grounding electrical circuit. Make sure the ground loop
resistance is < 4 ohms.
The electrical cable is inserted into the water heater through the rear wall of the device and
connected to the connecting block, according to the marking on the rear panel of the device,
where " " is the ground wire, "L" is the phase wire, "N" is the neutral wire. To enter the
electrical cable and connect it, it is necessary to remove the front panel of the device by
unscrewing the fixing screws in its lower part. After connecting the electrical cable to the
connection block, make sure that all clamping screws of the block are tightened securely. Fasten
the cable inside the heater using the clamping plate, replace the front panel and tighten the fixing
screws at the top and bottom of the device.
* for connection to the electrical network, this series of water heater is completed with a power
cord and a plug, 1.5 m long and with a copper conductor cross section of 3x1.5 mm
