This section contains information instructions and warnings that the user must follow by its own
security and to ensure safe operation of the device.

regulators are usually connected to equipment containing ca-
pacitors, which remain charged after removing supply voltage. To avoid risk of
electric shock, you must wait at least 5 minutes between the disconnection of
the equipment and handling of the internal components thereof.
Any handling or use of equipment in different way or conditions to that
specified by the manufacturer, may compromise the user safety.
In case that some damage or deterioration signs are detected in the device or a wrong opera-
tion is observed, disconnect the supply voltage and contact CIRCUTOR authorized technical
service.
To safely use the computer MAX 6 and computer MAX 12 it is important that people installing
it or handling it follow the usual safety precautions stated in the LV or MV Electrical Code Rules
of each Country as well as the different warnings stated in this instruction manual.
4.1.- MECHANICAL INSTALLATION
Mechanically, the device is intended to be mounted attached to the front door of the cabinet.
The fitting hole must be according to DIN 43 700, (dimensions 138
+1
x138
+1
mm).
4.2.- CONNECTIONS
Before connecting the supply to the device check the following items:
The installation and maintenance of the device must be carried out by specialised
and dully trained staff, according to National Electric Codes and Rules and Inter-
national Standards.
All the connections must be at the inner part of a protection cabinet.
Notice that when the device is connected to supply, the voltage at certain termi-
nals can be hazardous and cause electric shock in case of contact. Opening the
electrical cabinet or removing certain covers can compromise the user safety and
should only be done by qualified and authorized staff.
The computer MAX devices are used together with capacitor banks, which can
remain charged after supply disconnection. In order to avoid shock hazard, wait
during 5 minutes after supply disconnection before any manipulation inside the
equipment cabinet.

devices require current sensing of the installation. A current transformer (CT)
must be installed externally to perform this function. Usually the current ratio of the CT is In / 5
A , where In must be at least 1,5 times the Maximum expected load current.
The CT must be installed at the incoming supply line (point of coupling of the user), so that
