Rockwell Automation 440N SensaGuard Magnetically Coded NonContact Switch (MC2) - Manual (Page 3)

1. Installation Instructions
Installation must be in accordance with the following steps and stated specifications and should be carried out by suit-
able competent personnel. The unit is not to be used as a mechanical stop. Guard stops and guides must be fitted.
Adherence to the recommended maintenance instructions forms part of the warranty.
This device is intended to be part of the safety related control system of a machine. Before installation, a risk assess-
ment should be performed to determine whether the specifications of this device are suitable for all foreseeable opera-
tional and environmental characteristics of the machine to which it is to be fitted. Refer to Technical Specifications for
Certification information and ratings.
ATTENTION: The presence of spare actuators compromise the integrity of the safety systems. Personal
injury or death, property damage or economic loss can result. Appropriate management con-
trols, working procedures and alternative protective measures should be introduced to control
their use and availability.
WARNING: Do not defeat, tamper, remove or bypass this unit. Severe injury to personnel could result.
