• Installation in Zone 0 (electronics: NAMUR): The intrinsic safe supply circuit must have
galvanic isolation to a non- intrinsically safe area. Otherwise, provide protection for the
device against lightning strikes (see EN 60079-14).
• Power supply (electronics: NAMUR): Intrinsically safe protection is only valid when
connected to a certified intrinsically safe power supply.
• For the LVS Pipe extended and cable extended models with Namur electronics for gas
hazardous approvals: When mounting the units on a vessel lid that separates Zone 0
(Cat. 1G) from Zone 1 (Cat 2G), the units have no safe separation between Zone 0 and
Zone 1. Gas can pass from Zone 0 through the unit to Zone 1.
