INSTALLATION MANUAL
Our compliments for your excellent choice. The GR300-400-600 electro-mechanical gear motor has been produced for
reliability and high uality. This Manual will offer information you may need to install your gear motor assuring long-lasting
performance and to safeguard your safety.
HOWEVER CAUTION IS UNQUESTIONABLY INDISPENSABLE AND NOTHING IS BETTER THAN PREVENTING ACCIDENTS. GR
products have been made to conform with rules and laws in force at time of manufacture.
This manual is designed exclusively for the specialized installation expert in the criteria of construction and e uipment
to assist in the protection against accidents in the installation and use of the gate; door and automation of such gates (adhere
to the rules and laws in force).
On completion the installer should issue to the end consumer an instruction manual according to EN 12635.
Before proceeding with the installation the installer must provide an analysis of the identification and management of
risks as per the standards EN 12453 and EN 12445.
All wiring of the various external electrical components connected to the automation (e.g. Photocells, flashing lights,
keypads etc) must be carried out according to EN 60204-1 and the amendments made of the point 5.2.2 of EN 12453.
It is prohibited to do any repair or adjustment of the e uipment if you have not taken all necessary precautions to avoid
possible accidents (example: power supply disconnected, engine block). All mechanisms in motion must be e uipped with
appropriate protections.
The mains power line must be protected for maximum current in locked rotor condition as per government electrical
laws.
Install the gear motor on gates that conform to EN 12604.
Perform the measure of strength developed by the gear motor and take the appropriate steps as per EN 12445.
Positioning photocells: These safety devices must be installed at a height not exceeding 70cm from the ground and at a
distance from the floor movement of the door of no more than 20cm. Their proper functioning of the photocells must be
verified at the end of installation according to Section 7.2.1 of EN12445.
Keep the activation controls of automation out of reach of children. The controls should be installed at a minimum 1.5m
height above the ground and outside the range of actions of moving parts such as the gate.
All activation actions must be executed only at points from where the automation is fully visible.
Operate the remote only in view of automation.
Store carefully this manual in a suitable place known to all interested people.
Any unauthorized and arbitrary modification made to this product, releases the company GR Sistemi Automatici di apertura
Srl and from any liability resulting from damage or injury to things, people or animals.
The non-observance of regulations and of safety standards here listed releases the company GR Sistemi Automatici di

explosive mixtures!
Electric Shock!
Use gloves!
Use welding glasses!
Maintain ear protection!
MAINTENANCE
All repairs must be carried out by ualified people.
Before each intervention remove power through the switch
and lock in that position
The e uipment must be maintained so as to preserve the
conditions that ensure safe and efficient operation
Always use original spare parts
Do not make interventions that modify the machine.
The modified e uipment re uires new CE mark
The settings of the operator must be performed by
ualified personnel, in accordance with the rules of reference.
During these operations provide the presence of two operators
for safety.
DEMOLITION
You have to operate the elimination of the materials in
conformity with the regulations in force. All materials must be
divided by type (copper, aluminium, plastic, electrical parts, etc)
DISMANTLING
In order to move away the automation, follow these
instructions:
1 - cut off the power supply and disconnect the electrical
installation;
2 - dismantle the control console and all the other components
of the installation.
If you have noticed that some components have been damaged,
you have to replace them.
CONFORMITY DECLARATION:
It’s in accordance with Machine Directive 39/89/CE and following
modify.
It’s in accordance with the following directive CE:
Electromagnetic compatibility Directive 89/336/CEE and
following modify.
Low tension Directive 73/23/CEE and following modify.
Have been applied the following harmonized norms:
EN292/1/2, EN 294, EN60335-1, UNI EN 12453, and what
applicable of the EN12445-2000.
USE OF THE AUTOMATION
The gearmotor GR300-400-600 was designed and built for the
opening of gates with max of 5 m leaf or weight max. 300kg.
The GR Srl assumes no responsibility for a purpose other than
that provided by gearmotor GR300-400-600. Since automation
can be put into motion in view by button or remotely by remote
control, it is essential to check fre uently the perfect efficiency
of all safety devices. It is advisable to check periodically (every
six months) the regulation of electronic friction of which must be
e uipped the electronic control board.
PRELIMINARY CHECKS
1 - Read carefully the instructions enclosed in this manual.
2 - Make sure that the gate has a rather solid structure and that
there is no friction points in its movement.
3 - Make sure that the leaf is suitably balanced, even after the
installation of the gear motor.
4 - Check that the electrical installation is in accordance with the
characteristic re uired by the gear motor.
