Specific conditions for use
• Before taking into use, the user shall make an evaluation of the compatibility between process media
and the materials in the 1400 or 3400 Expert TM
• The equipment must be connected via an approved or certified interface/zener barrier placed out
side the hazardous area.
• For installations in which both the Ci and Li of the connected apparatus exceeds 1% of the Co and Lo
parameters (excluding the cable), then 50% of Co and Lo parameters are applicable and shall not be
exceeded.
• For model 3400 Expert Level Transmitter: Warning - Clean only with a damp cloth to prevent the
TM
possibility of electrostatic discharge.
The maximum length of the cable is calculated from the Expert pressure transmitters internal capacity
(3,5 nF) and internal self-induction (7 μH). The cable capacity (MJK 0,8nF/m) and the self-induction (MJK
1.5 μH/m) is added.
The 2 values are added to calculate the total capacity and the total self-induction. The Ex isolator or
Zener barrier is marked with the maximum capacity and self-induction for the connection. These two
values must never be exceeded.
