The dimensioning of the load cable and the fusing must be in accordance with the machine's technical data
and the local regulations of the power supply company.
The supply cable must be routed into the machine. Cut-outs are provided for this purpose in the baseplate
and in the compressor mount (cBoxX 40 – cBoxX 100). Feed the supply cable, protected by rubber grommets,
through these openings
(see
Figure 16 Main supply
).
Please note that the dimensions described in DIN VDE
0298-4 must be observed.
Never switch on the chiller immediately if the machine is moved from a cold into a warm room. The
condensing moisture can damage electronic components. For the initial startup or following a lengthy period
out of use all the electronic components must have become acclimatised.
Use an external control cable to set the chiller's release (see
Chapter 8.3 External release
) of the Chiller. This
must be laid separately from the supply line and wired to the appropriate terminals in the switch cabinet.
(see wiring diagram included in the unit)
Once the electrical installation has been completed the phase sequence must be tested. This is done by
checking the rotational direction of the pump. This has a rotational direction arrow on it. If the rotational
direction does not match the arrow, the phase sequence can be corrected by swapping two phases at the
main supply.

Commissioning
Before commissioning the chiller the checklist must be used to check whether all the necessary work in
Chapter 6 Installation
has been carried out properly.
The chiller must be installed for at least 12 hours at >+5 °C, so that the compressor oil can heat up and the
refrigerant can be liberated from the oil.
If your machine is equipped with oil sump heating and the machine has been completely installed, it is
permissible to switch on the machine at the main switch and to allow the compressor to be preheated for at
least 3 hours without enabling the cooling.
