2. Safety advice
2.1 Basic safety advice
Please read the safety and operating advice carefully, and observe the advice when operat-
ing the LLD-500 laser distance measurement device.
Danger, laser radiation. The LLD-500 must not be opened unauthorized, otherwise laser ra-
diation can be emitted that can cause injuries to the eyes. Please observe all information and
guidelines for operating the laser.
Danger, electric shock
The LLD-500 may only be opened for repair purposes by the manufacturer. If the device is
opened arbitrarily without authorization, all warranty claims will expire.
The operating and storage conditions ( chapter 9) have to be observed. The non- observance
of this advice and the adverse use of the device can lead to injuries of the user or to damage
of the device.
Connectors may not be plugged or unplugged when voltage is applied.
All installation work may only be carried out when no voltage is applied.
The device may only be operated as intended and in faultless condition.
Safety installations must not be rendered ineffective.
Safety and warning signs must not be removed.
Protection degree:
In accordance with the protection degree IP67, the LLD-500 is protected against jet water
and dust, and against short submersion into water.
When operating the device under extreme outdoor environmental conditions, the use of addi-
tional weather protection is recommended (e.g. a cover plate with a short distance to the
LLD-500). Rapid temperature changes can lead to humidity entering the device.
If the device is exposed to humidity, the temperature difference between the de- vice and the
environment may be ± 5K maximum.
The device is not shatter-proof. Do not let the device fall onto the ground, and avoid any agi-
tation.
The device may not be used in explosive environments; otherwise there is the danger of
damage to the LLD-500 and the surrounding equipment, and of injuries of the user.
