Installation Instructions
Installation must be in accordance with the following steps and stated specifications and should be
carried out by suitable 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 assessment should be performed to determine whether the specifications of this device are suit-
able for all foreseeable operational 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 sys-
tems. Personal injury or death, property damage or economic loss can result.
Appropriate management controls, working procedures and alternative protec-
tive measures should be introduced to control their use and availability.
