Special Conditions for Safe Use
Intrinsically Safe
This equipment is intrinsically safe and can be used in potentially explosive atmospheres.
The electrical parameters of certified equipment which can be connected to the device must not exceed the following
≤ 30 VDC ; I
values: U
0 0
Ambient temperature: T5, at Tamb = 40_C ; T4, at Tamb = 71_C
Flameproof
The flame path is other than required by EN 60079‐1. Contact the manufacturer for information on the dimensions of
the flameproof joints.
Electrical connections are typically made using either cable or conduit.
D If using a cable connection, the cable entry device shall be certified in type of explosion protection flameproof
enclosure "d", suitable for the conditions of use and correctly installed.
For ambient temperatures over 70_C, cables and cable glands suitable for at least 90_C shall be used.
