Original Instructions
GuardShield Micro 400 Safety Light Curtains
Catalog Numbers 445L-P4xFP, 445L-C4xFP, 445L-P4xKP
ATTENTION:
• Do not use the GuardShield™ Micro 400 safety light curtain with
machines that cannot stop electrically in an emergency.
• Always maintain the safety distance between the GuardShield
Micro 400 safety light curtain and a dangerous machine
movement.
• Install additional mechanical protective devices so you cannot
reach the hazardous machine elements without passing
through the protective field.
• Install the GuardShield Micro 400 safety light curtain so you can
only access the hazard through the sensing field.
• Improper installation can result in serious injury.
• Never connect the outputs to +24V DC. If the outputs connect to
+24V DC, they are in the on-state and cannot stop hazardous
spots at the machine/application.
• Never expose the GuardShield Micro 400 safety light curtain to
flammable or explosive gases.
• Regular safety inspections are imperative (see
Inspection on page
Only use the GuardShield Micro 400 safety light curtain as defined in these
instructions and publications that are listed in
Only qualified personnel can install, commission, service, and use this safety light
curtain, and only on the machine that the device was intended.
If the device is used for any other purposes or modified in any way, warranty
claims against Allen-Bradley/Guardmaster become null and void.
IMPORTANT Observe the following items to maintain the proper and
safe use of the GuardShield Micro 400 safety light curtain.
The national/international rules and regulations apply to the installation, use, and
periodic technical inspections of the safety light curtain, in particular:
• Machinery Directive 2006/42/EC
• Low Voltage Directive 2014/35/EU
• Use of Work Directive 2009/104/EC
• The work safety regulations/safety rules
• Other relevant health and safety regulations
Manufacturers and users of the machine that uses the safety light curtain are
responsible for obtaining and observing all applicable safety regulations and rules.
