2 .. 1 -CONFORMITY
Press brakes are shipped from the factory with basic safety equipment including:
Adouble
foot pedal (close/open).
A switch-operated mode selector.
Lateral protection
Back protection
SeH-supervising electrical and hydraulic circuits
Optional:
equipment for a second operator.
2.2 -SAFETY INSTRUCTIONS FOR PRESS BRAKES
Do not use, adjust or undertake any action on the machine without first having read the instructions.
Observe all safety instructions when using this press.
Do not place hands between tools.
Do not place hands between tools to adjust the back gauge.
Do not operate press if side or rear safety panels are not in place.
Do not remain between the protective pieces and the danger area.
Before any operation make sure that :
-all protective devices are in place
- the operating cycle is correct for the work to be done
-nothing is interfering in-between the tools
- there is open access to the various parts of the machine
- the floor around the machine is free of grease, oil or water.
Make sure that gloves are worn during operation

2.3 - RULES FOR SAFE OPERATIC)N
Use pliers or any other tooling to help bend small dimension or small width parts. Never
place your fingers nearthe punches.
Remove your hands form the part to be bent after the latter has been pinched between the tools.
Otherwise this might result in serious injuries.
Make sure that the operator removes the punches and the tooling in compliance with the
procedure described in this manual. Make sure that the motor is stopped at that moment.
2-2/4
INSTALLATION MANUEL- 00:03/90

PROMECAM
Never place your hand between the part and the rear gate while operating your machine.
Never place any part of your body between the die and the punch during a bending operation.
Never try to support the end of the workpiece by supporting it on both sides of the beam.
ITS/ITPS • SAFETY
2·3/4

PROMECAM
Take care of sudden rising of the beam. Make sure that the part is bent slowly if it is large.
,
Make sure that the tools are used within the prescribed safety_pressures The tools might break
into pieces and be scattered
if the safety pressure is exceeded.
If two operators are to work on the machine, make sure that use of the pedal is limited to the main
operator and that the pedals are actuated only after receiving a sign from the other operator; the
same caution should be taken for dual control operation.

3 -INSTALLATION REQUIREMENTS
3.1 -ELECTRICAL CONNECTION
The proper operation of an electrical system depends on the quality of the power supply, it should be
stable and free
of disturbances.
Installation should be planned and carried out so as to meet currently applicable regulations.
3.1.1 -GENERAL MAINS CHARACTERISTICS

Specialized line to be exclusively reserved for the
system from the general
LOW VOLTAGE board.
The whole system is powered
by a single 3-phase cable with
earth (possibly also with neutraQ
3.1 .2 -EARTH
In pursuance with applicable standards any equipment which is not provided with double installation
requires an earthing connector. This is also required at operational level and
for floor earth drainage
of electrical noise interferences.
-The cross section
of the earthing conductor must be sufficient. For maximum security earthing
distribution should be made in a STAR CONFIGURATION beginning from the power board
terminal. As in any other electrical installation the quality of the ground connection should be
verified periodically by an approved organization.
-The earthing resistance measured at the bar closest to the earth terminal should be less than 6
ohms.
-The earthing conductor (green and yellow), is reserved exclusively for the system. It is connected
directly to the earthing bar.

3.1.3 -INTERFERENCES RELATED TO MAINS AND ENVIRONMENT
IMPORTANT
DO NOT UNDER ANY CIRCUMSTANCES WELD A PIECE TO THE MACHINE. YOU
COULD DAMAGE THE MECHANICAL, ELECTRICAL AND ELECTRONIC COMPONENTS.
The distribution network introduces some interferences (micro-powercuts, frequency drifts,
harmonics, interferences etc...). These might be detrimental to the correct operation of the system.
So, some electonic components might therefore be submitted to abnormal or excessive voltages and
currents causing their damage beyond repair.
It may be necessary to provide for some adapter elements without galvanic connection to mains
(voltage stablizer, rectifier, converter, transformer, insulation transformer etc...). If required the quality
of this electrical power supply should be checked by an approved organization and analysis of the
results should determine the required equipment type.
The following interference must be considered as disturbing for
any electronic system:
Electrostatic discharges
These are very critical in an environment with relatively low ambient humidity : people or moving
assemblies often create a discharge of several thousand volts by touching a door handle or a metal
upright or, even worse, the chassis. Therefore, it is necessary to provide for an antistatic
environment (anti-static carpetfor example).
Transient on mains powersupply
Transient are electrical noise pulses propagated along the mains leads which may affect system
operation. Their origin may be
internal: motor, lift, refrigerator, air conditioning unit, fluorescent tube
or any other machine generating mains noise :
or external : stormy weather, neighbouring plant ...
Transient specifications accepted by the system are
50% of the nominal voltage for a maximum
duration of 5 ms.
Stormy weather
The charges accumulated in stormy conditions result in transient on the mains or on the connecting
cables.
Magnetic fields
A variable magnetic field induces a voltage into a closed circuit creating considerable interference.
Cathode ray tubes are sensitive to magnetic fields.
Their sensitivity is materialized by faulty
chromatics of the image or of its geometry.
Tl1ese are therefore fitted with a protective shielding.
Medlum- or high-frequency electro-magne!tic radiation
This interference type may be the origin of a large number of problems in the systems (operational
amplifiers, DP memory). Generally, the
ma~Jnitude of such disturbances depends of the radiation
duration and intensity. They may be due
to RADAR installations (near airports for instance) or to
radio frequency transmitters (military, civil, Police, Stations, FM
.. ) or even to defective or badly
filtered discharge tubes. Walkie-talkies can pll'Oduce the same effect when used near input channels.
The reference value to be taken into consideration corresponds to an 0.2 to 0.5 VIM field in a
frequency range of
10KHz to 1 GHZ.

We recommend the installation of a circuit protector or breaker at the head of the line.
Cable may be led in from the floor (fig 3.2) or on an aerial line (fig 3. 1).
The power cable should, in no event, pass through the control box or channel located on its front.
The main switch located in the electrical cabinet is designed to receive up to three safety padlocks.
We advise that you immediately install a lock so as to prevent untimely power-up.

Check your mains voltage. This value should be specified to the AMADA agent who will connect and
start your machine.

4 -SITE AND ENVIRONMENTAL PREPARATION
Press brakes installation requires a stable, rigid ground surface.
Flooring in the work area should be a 50 mm thick concrete
slab, with a plane surface (maximum
tolerance 2 mm per metet'). For the installation conditions please consu It our technical department.
Access to the press shou Id be provided on all four sides :
-At the back leave a space of approximately 1 meter for maintenance operations and adjustments.
-On at least one of the sides provide for a space slightly above the maximum bending length, so
that lateral withdrawal removal of some parts is allowed on the whole press brake lengh
(dimension
A, Figure1).

The handling operations are to be performed as follows:
a) Use lifting means such as travelling bridges or cranes. .'
Use the slinging point (40 mm diameter holes on each upright). These holes can directly receive
the shackles where the lifting slings will be secured.
b) If no appropriate lifting equipment is available the press may be moved on small tractors
(Fig 5.3).
In this case carefully campi ywith the allowed bearing points:
