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 suitable for all foreseeable operational and
environmental characteristics of the machine to which it is to be
fitted. Refer to Technical Specifications below for certification
information and ratings.
The presence of spare actuators compromise the
ATTENTION
integrity of the safety systems. Personal injury or
death, property damage or economic loss can
result. Appropriate management controls,
working procedures and alternative protective
measures should be introduced to control their
use and availability.
Do not defeat, tamper, remove or bypass this unit.
Severe injury to personnel could result. The sensor
MUST be connected to a Class 2 SELV 24V DC,
+10%/-15% power supply.

Mounting Information
Use non-removable screws, bolts, or nuts to mount the switch and
actuator. Do not over torque the mounting hardware.
Position the switch and actuator so they are aligned with each
other.
Mount the switch and actuator to removable guard, door, or gate.
Keep the switch and actuator within the sensing range below.
