Connection Of The Backup Heater Power Supply - Daikin Altherna Serie Manual De Instalación

Precautions on wiring of power supply
Use a round crimp-style terminal for connection to the power
supply terminal board. In case it cannot be used due to
unavoidable reasons, be sure to observe the following
instruction.
1 Round pressure terminal
2 Cut out section
3 Cup washer

- Do not connect wires of different gauge to the same power
supply terminal. (Looseness in the connection may cause
overheating.)
- When connecting wires of the same gauge, connect them
according to the below figure.
Use the correct screwdriver to tighten the terminal screws.
Small screwdrivers can damage the screw head and prevent
appropriate tightening.
Over-tightening the terminal screws can damage the screws.
See the table below for tightening torques for the terminal
screws.

Attach an earth leakage circuit breaker and fuse to the power
supply line.
In wiring, make certain that prescribed wires are used, carry out
complete connections, and fix the wires so that outside forces
are not applied to the terminals.

Connection of the backup heater power supply

Power circuit and cable requirements
Be sure to use a dedicated power circuit for the
backup heater. Never use a power circuit shared by
another appliance.
Use one and same dedicated power supply for the
unit, backup heater and booster heater (domestic hot
water tank).
This power circuit must be protected with the required safety devices
according to local and national regulations.
Select the power cable in accordance with relevant local and national
regulations. For the maximum running current of the backup heater,
refer to the table below.
