(3) Installation
WARNING
• All wiring shall comply with local installation
requirements and local electrical code.
• In hazardous locations, the cable entry devices
shall be of a certified ATEX flameproof type,
suitable for the conditions of use and correctly
installed.
• Unused apertures shall be closed with suitable
flameproof certified blanking elements. (The
plug attached is flameproof certified.)
(4) Operation
(Integral Flowmeter)
WARNING
• After de-energizing, delay 20 minutes before
opening.
• Take care not to generate mechanical spark
when access to the instrument and peripheral
devices in hazardous locations.
