WARNING: Endangerment of electrical safety during installation and
maintenance work when the power supply is not switched off
An electrical accident can occur during installation and maintenance work when the
power supply to the device or lines is not switched off using a power isolating switch/
circuit breaker.
▸
Before starting the work on the device, ensure the power supply can be switched off
using a power isolating switch/circuit breaker in accordance with DIN EN 61010.
▸
Make sure the power isolating switch is easily accessible.
▸
An additional separation device is mandatory when the power isolating switch cannot
be accessed or only with difficulty after installation of the device connection.
▸
After completion of the work or for test purposes, the power supply may only be
activated again by authorized personnel complying with the safety regulations.
WARNING: Endangerment of electrical safety through power cable with
incorrect rating
Electrical accidents can occur when the specifications of a replacement for a removable
power line have not been adequately observed.
▸
Always observe the exact specifications in the Operating Instructions (Technical Data
Section) when replacing a removable power cable.
WARNING: Hazard by voltage
▸
All connectors of the power supply to the involved subassemblies or lines must be
disconnected before the installation work.
CAUTION: Device damage through incorrect or non-existing grounding
During installation and maintenance work, it must be ensured that the protective
grounding to the devices and/or lines involved is effective in accordance with
EN 61010-1.
CAUTION: Eye injuries caused by improper handling of UV or blue light beams
The UV beam of the deuterium lamp or the blue light beam of the LED can cause serious
injuries through direct eye and skin contact. This results in the following safety
measures when working on the switched on device with access to the light beam exit:
▸
Always wear UV protective goggles (in accordance with standard EN 170).
▸
The UV goggles do not provide protection against injuries caused by blue light beams,
therefore switch the LED off when working.
▸
Use the lamps only when they are perfectly safe. Operation is not allowed when the
lamp, supply lines or operating parts are visibly damaged.
WARNING: Risk of explosion in potentially explosive atmospheres
!
▸
Do not use the GM32 in potentially explosive atmospheres.
