Notes RLA is based on following conditions: indoor temperature: 27°CDB/19°CWB, outdoor temperature: 35°CDB
Voltage range: units are suitable for use on electrical systems where voltage supplied to unit terminal is not below or above listed range limits
Maximum allowable voltage range variation between phases is 2%.Select wire size based on the value of MCA
Instead of fuse, use circuit breaker. MFA is used to select circuit breaker and the ground fault circuit interrupter (earth leakage circuit breaker).
MSC means the maximum current during start up of the compressorEN/IEC 61000-3-12: European/international technical standard setting the limits for harmonic currents produced by equipment connected to public low-voltage system with input current > 16A and <= 75A per

3TW30402-1
Integrated heating capacity coefficientThe heating capacity tables do not take account of the reduction in capacity, when frost has accumulated or while the defrosting operation is in progress.The capacity values, which take these factors into account, in other words, the integrated heating capacity values, can be calculated as follows
Formula:Integrated heating capacity = AValue given in table of capacity characteristics = BIntegrating correction factor for frost accumulation (kW) = CA = B x C
Correction factor for finding integrated heating capacity

Please note that, when there is an accumulation of snow against the outside surface of the outdoor unit heatexchanger, there will always be a temporary redusion in capacity, although this will of course vary in degree inaccordance with a number of other factors, such as the outdoor temperature (°CDB), relative humidity (RH) andthe amount of frosting which occurs.
Note:1. The figure shows that the integrated heating capacity
expresses the integrated capacity for a single cycle (fromdefrost operation to defrost operation) in terms of time.

Notes:1 All wiring, components and materials to be procured on the site must comply
with the applicable local and national codes.2 Use copper conductors only.3 For more details, see wiring diagram.4 Install a circuit breaker for safety.5 All field wiring and components must be provided by a licensed electrician.6 The unit shall be grounded in compliance with the applicable local and national
codes.7 Wiring shown are general points-of-connection guides only and are not intended
for or to include all details for a specific installation.8 Be sure to install the switch and the fuse to the power line of each equipment.9 Install the main switch that can interrupt all power sources in an integrated
manner because this system consists of the equipment utilizing the multiplepower sources.
10 For detailed control box side connection, see control box manual and wiringdiagram.
