Introduction
This manual has been especially written for use by qualifi ed fi tters. No information given in this
manual can be considered as being of interest to end users. This manual is enclosed with control
unit D750M and may therefore not be used for different products!
Important information:
Disconnect the panel from the power supply before opening it.
The D750M control unit has been designed to control an electromechanical gear motor for automating
gates and doors of all kinds.
Any other use is considered improper and is consequently forbidden by current laws.
Please note that the automation system you are going to install is classifi ed as "machine construction"
and therefore is included in the application of European directive 98/37/EC (Machinery Directive).
This directive includes the following prescriptions:
- Only trained and qualifi ed personnel should install the equipment;
- the installer must fi rst make a "risk analysis" of the machine;
- the equipment must be installed in a correct and workmanlike manner in compliance with all the
standards concerned;
- after installation, the machine owner must be given the "declaration of conformity".
This product may only be installed and serviced by qualifi ed personnel in compliance with current,
laws, regulations and directives.
When designing its products, TAU observes all applicable standards (please see the attached
declaration of conformity) but it is of paramount importance that installers strictly observe the same
standards when installing the system.
Unqualifi ed personnel or those who are unaware of the standards applicable to the "automatic
gates and doors" category may not install systems under any circumstances.
Whoever ignores such standards shall be held responsible for any damage caused by the sys-
tem!
Do not install the unit before you have read all the instructions.
Before proceeding, make sure the mechanical components work correctly. Also check that
the gear motor assembly has been installed according to the instructions.
THE EQUIPMENT MUST BE INSTALLED "EXPERTLY" BY QUALIFIED PERSONNEL AS
REQUIRED BY LAW.
In particular:
1. position the board vertically and as near as possible to the gear motor, taking care to keep the
connection cables as short as possible;
2. make sure the cross-section of the power cables (power input, motors, earth and fl ashing light)
is at least 1.5 mm² and, in any case, suffi cient for the absorption and length of the wires. The
above also applies to the other cables used by control and auxiliary devices except that the
minimum cross-section is reduced to 0.5 mm²;
3. make connections to the terminal board so as not to alter the level of protection offered by the
container which must be installed in a dry and protected place;
4. keep the power circuits separate from the control and auxiliary circuits, especially if the cables
are long;
5. short any unused Normally Closed contacts.
NB : it is compulsory to earth the system and to observe the safety regulations that are in force in
each country.
IF THESE ABOVE INSTRUCTIONS ARE NOT FOLLOWED IT COULD PREJUDICE THE
PROPER WORKING ORDER OF THE EQUIPMENT AND CREATE HAZARDOUS SITUATIONS
FOR PEOPLE. FOR THIS REASON THE "MANUFACTURER" DECLINES ALL RESPONSIBILITY
FOR ANY MALFUNCTIONING AND DAMAGES THUS RESULTING.
