3.1. Location
The APC are suitable for indoor installation, on appropriate surfaces. Shelter the equipment from dust and
moisture and place it in a well-ventilated area where the ambient temperature doesn't exceed the following
values:
40°C maximum;
35°C over 24h;
25°C over one year.
Appropriate action must be taken for ambient temperature down to -5°C or above 40°C.
3.2. Harmonics
The installation of capacitors on networks disturbed by harmonics may require special precautions especially
when there is a risk of resonance.
Consult your closest local ABB agent if it is the case.
3.3. Fixation
3.3.1. APCL2 box
Fix the box on the wall by means of the fixation kit provided for this purpose.
The ground clearance must be of 10 cm minimum.
It's advised to keep a distance of 10 cm between the boxes.

3.4. Connection
Cabling of equipment requires three main power connection (no neutral required) to each unit, two control
wires from the current transformer to the master unit and, in case of master unit + slave unit configuration,
the wiring of the interconnection cable from the slave unit to the master unit. The interconnection cable is
factory wired in the slave unit.
