All three-phase drives (compressor,
pumps, fans) must be connected to a
CLOCKWISE field of rotation. A short-
term operation in the wrong field of
rotation will lead to compressor dam-
age. OCHSNER accepts no liability for
this.
The leakage current protective
measures and the earth connection
necessary for the system are to be
inspected by a qualified electrician
before commissioning.
The compres-
sor motor is not protected by a circuit
breaker in the main supply circuit
.
The switching equipment used to
switch off all poles of the power sup-
plies to the system must conform to
the safety requirements of
EN 60204-
1, Section 5 and 13.4.5 as well as in-
ternational IEC 60947 standards.
When servicing the system, all power
supplied to the heat pump are to be
switched off and the safety measures
according to EN 50110-1 adhered to.
Should the safety requirements or
precautions not be adhered to, this
could lead to serious bodily injuries or
death.
4.9.2 Cable cross sections
Conventional wiring is to be used for sensors and
actuators. The following guidelines are to be ob-
served:
Position Minimum
cross sec-
tion
Supply cable 230VAC:
Connecting cables are always to be sized
according to on-site conditions
1.5 mm²
Control cable 230VAC:
(pumps, valve motors)
1.0 mm²
Sensor cables:
(outside sensors, etc.) must always be run
separately (min. 20 cm) from 230V/400V
cables. If separation is not possible,
sheathed cables are to be used. Sheathing
is to be connected to PE on the heat pump.
The maximum cable length must not ex-
ceed 50 m.
1.0 mm²
Bus cables:
Must always be run as sheathed cabling
(e.g.: eBus from OTE control to room re-
mote controls, auxiliary modules or bus
connections for cascading, etc.) The
sheathing is to be earthed.
OCHSNER recommends the following con-
ventional cables: Y(ST)Y) 2x2x0.8
Attention: Always used a twisted core pair!
0.8 mm²
Pulse cables for the stepping motor of an
electronic expansion valve are to be
sheathed.
OCHSNER recommends
ÖLFLEX® CLASSIC 100 CY
1.0 mm²

4.9.3 Evaporator wiring
The drives and the sensors on the evaporator are
supplied from the inside unit. For this, the follow-
ing cables are necessary from the inside unit to
the evaporator.
Motors/Sensors Cable
230V power supply to fan 3 x 1.5 mm²
Fan alarm 2 x 1.5 mm²
De-icing sensors TQA, TQE 4 x 1 mm²
Electronic expansion valve 4 x 1 mm²
S2 sensor for electronic expansion valve 2 x 1 mm²
