5.2 ELECTRICAL INSTALLATION IN HAZARDOUS AREA
5.2.1 GENERAL INFORMATION AND INSTRUCTIONS
Cautions
• Mounting, electrical installation, start-up and maintenance of this device may only be
carried out by trained persons authorized by the operator of the facility. Persons must
read and understand this manual before carrying out its instructions.
• This device may only be operated by persons who are authorized and trained by the
operator of the facility. All instructions in this manual are to be observed.
• Make sure the measuring system is correctly wired up according to the wiring diagrams.
Protection against accidental contact is no longer assured when the enclosure cover is
removed or the panel cabinet is opened (danger from electrical shock). The enclosure
may only be opened by trained persons authorized by the operator of the facility.
• To maintain the degree of protection of at least IP65 in accordance with IEC 60529,
suitable cable entries and blanking elements must be used and correctly installed.
• Take careful notice of the "Safety rules, instructions and precautionary measures" in the
front of this manual.
• Chapter 4 shows general information regarding the electrical installation of your indicator.
This chapter gives additional specific information regarding Intrinsically safe installation
and overrules the information given in chapter 4.
• When installing this device in hazardous areas, the wiring and installation must comply
with the appropriate installation standards for your industry.
Safety instructions
• For the combined connection of the different supply, input and output circuits, the
instructions in this manual must be observed.
• From the safety point of view the circuits shall be considered to be connected to earth.
• For reasons of ESD and safety, always ground the metal enclosure properly as indicated
5 Electrical installation
• Do not combine metal front covers with non-metallic rear covers, vice versa and / or cable
glands. A metal cover on a non-metallic rear cover could lead to ESD. A metal cable
gland in a non-metallic enclosure could invalidate isolation.
• For enclosures and windows with a high surface resistance, potential charging hazard
exists. Do not rub these surfaces of the indicator. Clean window and enclosure only with a
lint-free cleaning cloth made damp with a mild soap solution.
