1 GENERAL PRESCRIPTIONS
1.1 SAFETY PRESCRIPTIONS
This installation manual is addressed exclusively to professionally skilled
personnel. Read all the instructions carefully before starting the installation
procedures. Any operations that are not expressly set down in these
instructions are to be considered prohibited; improper use may result
in damage to the product and place persons and property at risk. The
manufacturer declines all liability for failure to observe best technical practices
in barrier system construction and for any possible deformations that may
occur when using the product. Store this manual in a safe place for future
reference. The design and construction of the devices fitted on the LIMIT
model as well as this manual are in full compliance with statutory legislation.
In consideration of potential hazards that may arise during the installation
and use of LIMIT, also the installation procedures must be carried out in full
compliance with the applicable laws, standards and regulations; specifically:
1.2 INSTALLATION PRESCRIPTIONS
• Before starting the installation procedures make sure you have any
additional devices and materials that may be required to complete the
LIMIT barrier system in consideration of the specific application.
• The automation system must not be used until the transit area has been
made safe.
• Dispose of packaging materials in compliance with local regulations.
1.3 OPERATING PRESCRIPTIONS
• No modifications can be made to any part of the product unless
specified in this manual. Unauthorized modifications of the product are
likely to lead to malfunctions. The manufacturer declines all liability for
damage caused by unauthorized modifications.
• The parts of the automation system must never be immersed in water
or other liquids. During the installation procedures ensure that no solid
objects or liquids penetrate inside the control unit or other open devices.
• If liquids penetrate any parts of the automation system, disconnect the
electrical power supply immediately and consult technical service; the use
of LIMIT in such conditions may give rise to potentially hazardous situations.
• Keep all parts of the LIMIT barrier system away from heat sources and
open flames; exposure to heat or flames may damage the devices and
cause faults, fire, or hazardous situations.
• When the system remains unused for a long time, remove the
optional battery and store it in a dry place to avoid the risk of leakage
of harmful substances.
• Connect the control unit exclusively to an electric power supply line
equipped with an efficient protective earth conductor.
• Any operations that require parts of the LIMIT barrier system to be
opened must be performed with the control unit and the electrical
power supply disconnected; if the disconnect device is not clearly
visible from where you are working, attach a warning notice to the effect:
"WARNING - MAINTENANCE IN PROGRESS".
• In the case of tripping of circuit breakers or blowing of fuses, find the fault
and remedy it before resetting the circuit breaker or changing the fuse.
• If the fault cannot be remedied using the information given in this manual,
consult technical service.
