9.1.4 About electrical compliance
Only for ERGA04E▲V3▼, ERGA06E▲V3H▼ and ERGA08E▲V3H▼ (not for
ERGA04~08E▲V3A▼)
Equipment complying with EN/IEC 61000‑3‑12 (European/International Technical
Standard setting the limits for harmonic currents produced by equipment
connected to public low-voltage systems with input current >16A and ≤75A per
phase.).
Only for the backup heater of the indoor unit
See "9.3.2To connect the backup heater power supply"[4122].
9.1.5 About preferential kWh rate power supply
Electricity companies throughout the world work hard to provide reliable electric
service at competitive prices and are often authorised to bill clients at benefit
rates. E.g. time-of-use rates, seasonal rates, Wärmepumpentarif in Germany and
Austria, ...
This equipment allows for connection to such preferential kWh rate power supply
delivery systems.
Consult with the electricity company acting as provider at the site where this
equipment is to be installed to know whether it is appropriate to connect the
equipment in one of the preferential kWh rate power supply delivery systems
available, if any.
When the equipment is connected to such preferential kWh rate power supply, the
electricity company is allowed to:
▪ interrupt power supply to the equipment for certain periods of time;
▪ demand that the equipment ONLY consumes a limited amount of electricity
during certain periods of time.
The indoor unit is designed to receive an input signal by which the unit switches
into forced OFF mode. At that moment, the outdoor unit compressor will NOT
operate.
The wiring to the unit is different depending on whether the power supply is
interrupted or NOT.
