1. For your safety
The machine meets the requirements of safety standard ANSI
B11.3.
This chapter describes the safety concept. The chapter
describes how potential dangers can be avoided. The overview
of residual risks contains measures to be taken by the operator
in order to reduce the residual risks.
Notes
■The operator must adhere to the valid safety and accident
prevention regulations of the respective country and the
safety laws of the state and of the region!
■USA and Canada: TRUMPF also recommends that the
safety regulations for ANSI press brakes be observed.
Certain operations can be a source of danger during operation.
The documentation contains warnings before the instructions for
these activities. There are warning plates on the machine.
A warning contains signaling words that have been explained in
the following table:
Signaling word Description
DANGER ... refers to great dangers. If not avoided, it can result
in death and serious injuries.
WARNING Refers to a dangerous situation. It could lead to seri-
ous injuries, if it is not avoided.
CAUTION ... indicates a potentially dangerous situation. It could
lead to injuries, if it is not avoided.
NOTICE If such a situation is not observed, it can lead to dam-
age to property.
Signaling words Tab. 1-1
Example of a warning:
Risk of fatal injury due to falling load!
ØObserve safety regulations for the handling of heavy loads.
ØNever walk under a suspended load.
ØUse certified tackle and means of transportation of sufficient
size.
ØEmploy qualified technicians to transport the machine.
ØCarry out transport in accordance with the transport regula-
tions.

DANGER

2. Operational safety
The machine can result in the following dangers if it is used
inappropriately or for purposes other than those intended, or
else if it is not safe to operate:
■Dangers to the safety of the operator.
■Damage to the machine and to other property of the opera-
tor.
■Negative effect on the effective functioning of the machine.
2.1 Intended use
The user may use the machine only in the industrial sector.
Installation, operating and transport conditions defined by
TRUMPF must be adhered to and maintenance work must be
carried out in accordance with the Operator's manual. The user
must observe the specifications of the country in which the
machine is being operated as well as national and regional
safety and accident prevention regulations.
The user may bend cold sheets using the machine.
The following is not permitted:
■Unauthorized alteration or conversion of the machine by the
user or personnel.
■Any working procedure that impairs the safety.
■Processing of hot, splintering or brittle materials.
■Use of tools from other manufacturers without release by
TRUMPF.
■The storage of tools no longer required on the press beam.
Any use going beyond this is considered to be unauthorized
use. TRUMPF is not liable for any damage, especially personnel
injuries and production failures resulting from this. The risk is
borne solely by the operator. The warranty will be voided.

3. Hazards
3.1 Dangers due to the open electrical
cabinet
The electrical cabinet may be opened only by an electrician.
Electrical voltage!

ØKeep the electrical cabinet closed.
ØBefore opening the electrical cabinet: turn off the MAIN
SWITCH and secure it against being switched back on
again. Wait for the discharging time (at least 5 minutes).
Hot components!
Burns!
ØKeep electrical cabinet closed.
ØBefore opening the electrical cabinet: switch off the main
switch and secure against being switched back on.
ØWait for the cooling phase (minimum 5 minutes).
3.2 Hazards due to laser radiation
Laser products are divided into laser classes as per the Euro-
pean standard EN 60825-1 (USA: ANSI Z136.1, ANSI B11.21).
The laser class corresponds to the hazard level of the laser light
emitted.
Assembly Class Description
BendGuard optoelectronic safety
device
1 The accessible laser radiation is not dangerous under
normal, foreseeable conditions.
Laser classes Tab. 1-2
Risk of eye injuries due to laser radiation!
Laser radiation causes irreparable damage to the eyes.

upper dead point and the mute point.If the BendGuard is
pushed up by an obstacle (e.g. trapped hand) or if the light field
is interrupted, then the press beam will stop.
The press beam moves at reduced speed between the mute
point and the lower dead point. The optoelectronic safety device
is not active.
The machine is switched on and off via the main switch. The
main switch can be secured against being switched on again
using a padlock.
The main switch has the following positions:
Position Description
0 The machine is switched off and the voltage supply of the
machine is interrupted.
I The machine is switched on.
