6 Remove the selected knockout holes by tapping on the
attachment points with a flat head screwdriver and a hammer.
7 Install a cable protection in the knockout hole:
▪ It is recommended to install a PG type cable gland in the
knockout hole.
▪ When you do not use a cable gland, protect the cables with
vinyl tubes to prevent the edge of the knockout hole from
cutting the wires:

8 Route the cables out of the unit.
9 Reattach the service cover. See "14.2.2 To close the outdoor
unit"[425].
10 Connect an earth leakage circuit breaker and fuse to the power
supply line as specified in "17.2 Specifications of standard
wiring components"[433].
17.5 To connect the external outputs
SVS and SVEO output
The SVS and SVEO outputs are contacts on terminal X2M.
The SVS output is a contact on terminal X2M that closes in case a
leak is detected, failure or disconnection of the R32 sensor (located
in the indoor unit).
The SVEO output is a contact on terminal X2M that closes in case of
occurrence of general errors. See "8.1Error codes: Overview"[413]
and "22.1.1 Error codes: Overview" [4 42] for errors that will trigger
this output.
Outdoor output connection requirements
Voltage 220~240V
Maximum current 0.5A
Wire size Only use harmonised wiring providing double
insulation and suitable for the applicable
voltage.
2-core cable
Minimum cable section of 0.75mm²
NOTICE
Do NOT use the outputs as a power source. Instead, use
each output to energize a relay that controls the external
circuit.

INFORMATION
Sound data about the refrigerant leakage alarm are
available in the technical data sheet of the user interface.
E.g. the BRC1H52* controller generates an alarm of 65dB
(sound pressure, measured at 1 m distance from the
alarm).
17.6 To connect the cool/heat selector
switch option
NOTICE
Do NOT use the cool/heat selector switch in case the T3T4
input is used.
In order to control the cooling or heating operation from a central
location, the following optional cool/heat selector switch
(KRC19-26A) can be connected:
1 Connect the cool/heat selector switch to terminal X1M of the
cool/heat selector PCB.
