3 Safety Aspects
Before installing the system, please study the Installation Manual in its entirety.
WARNING
Follow the installation and operating instructions! Please read the instructions carefully in
its entirety before working on the system.
Hazardous voltage!
Disconnect the power before installing or servicing the equipment. Ignoring this warning
can result in severe personal injury or material damage. Read the instruction carefully to
ensure correct connection of all power and signal leads.
Make sure that the correct voltage is connected to the system.
Circuit breaker!
The installation must include a means of isolating electrical power by a clearly marked
switch or circuit breaker external to the system. The external switch or circuit breaker shall
be in close proximity to the system and within easy reach of the operator.
Overload protection!
For compliance with the safety requirements IEC 61010-1 (2010), the installation must
include a means of overcurrent protection to provide protection against excessive energy
being drawn from the power supply system in case of a fault in the equipment.
Protective earth!
The system must be connected to protective earth.
Installation and fault finding!
Electrical installation and fault finding on the system should only be undertaken by a suit-
ably trained and qualified engineer.
Warning Laser Hazard
Visible laser radiation. When the transceiver operates in pulsed mode, the laser is classified
as Class 1, which is safe under all conditions of normal use. When it op- erates in the
continuous mode (i.e. there is a steady light beam in the aligning mode), the laser is clas-
sified as Class 3R. Thus, please avoid eye exposure to direct or scattered radiation when
the transceiver operates in the continuous mode.
