Remove  the  selected  knockout  holes  by  tapping  on  the
attachment points with a flat head screwdriver and a hammer.

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:

WARNING

Avoid  sharp  edges  when  routing  cables  to  the  rear.  Make
sure  to  route  the  cables  through  the  left  side  of  the
accumulator foot when passing through the tunnel:

NOTICE

Precautions when making knockout holes:

▪ Avoid damaging the casing and underlying piping.

▪ After  making  the  knockout  holes,  we  recommend  to

remove  the  burrs  and  paint  the  edges  and  areas
around the edges using repair paint to prevent rusting.

▪ When  passing  electrical  wiring  through  the  knockout

holes,  wrap  the  wiring  with  protective  tape  to  prevent
damage.

To connect the external outputs

SVS output

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).
