General safety instructions
3.3 Electrical safety measures and fire prevention measures
The following safety instructions must be observed during the installation
and repair of cables that carry electrical power:
DANGER!
Sensors and controller are designed for compliance with the U.S. and
Canadian NEC as well as the European low voltage directive. No internal
electrical or electronic parts are allowed to be modified in any way, as this
could render the CE conformity void.
WARNING!
Only qualified experts may perform the tasks described in this section of the
manual, while adhering to all locally valid safety regulations.
• Prior to maintenance or repair of the instrument, isolate it from the power
supply.
• When making electrical connections, all applicable local and national
regulations are to be met.
• The use of earth leakage trips is strongly recommended.
• The instrument must be correctly earthed for correct operation.
This symbol, if present on the instrument, indicates that safety glasses must be worn.
This symbol, if present on the instrument, identifies the location of the connection for the protective earth (ground).
As of 12 August 2005, electrical appliances marked with this symbol are no longer allowed to be disposed of in
Europe in unsorted household or industrial waste. As per the applicable regulations (EU directive 2002/96/EC), from
this date on consumers in the EU must return old appliances to the manufacturer for disposal. This disposal is free of
charge for the consumer.
Note: You can obtain instructions on the correct disposal of all (marked and unmarked) electrical products that have
been supplied or manufactured by Hach-Lange from your local Hach-Lange sales office.
