SiEN34-705 Heat Pump 60Hz (RXYQ5~54P)
Installation Manual 287
2.7.1 Power Circuit, Safety Device, and Cable Requirements
! A power circuit (see the following table) must be provided for connection of the unit. This
circuit must be protected with the required safety devices, i.e. a main switch, a slow blow
fuse on each phase and an earth leakage circuit breaker.
! When using residual current operated circuit breakers, be sure to use a high-speed type (1
second or less) 200mA rated residual operating current.
! Use copper conductors only.
! Use insulated wire for the power cord.
! Select the power supply cable type and size in accordance with relevant local and national
regulations.
! Specifications for local wiring are in compliance with IEC60245.
! Use wire type H05VV when protected pipes are used.
Use wire type H07RN-F when protected pipes are not used.
Note: The above table indicates power specifications for standard combinations (see 2-2
Introduction).
If using anything other than the above combinations in a multi system, calculate using the
following procedure.
Minimum circuit amp value: add the minimum circuit amp values for each independent unit
Recommended fuse capacity: select the fuse capacity with the next higher value of the
calculated minimum circuit amp. multiplied by 1.1.
Ex: Combining the RXYQ30PYL using RXYQ8PYL, RXYQ10PYL, and RXYQ12PYL.
Minimum circuit amp. of the RXYQ8PYL in table above = 18.5 A
Minimum circuit amp. of RXYQ10PYL in table above = 22.8 A
Minimum circuit amp. of RXYQ12PYL in table above = 23.9 A
Accordingly, the minimum circuit amp. of the RXYQ30PYL = 18.5 + 22.8 + 23.9 = 65.2A
Multiplying the result above by 1.1 (65.2 × 1.1) = 71.7 A, so the recommended fuse capacity
would be 80 A.
