sure the instruments in the loop are installed in accordance with intrinsically safe or
non-incendive field wiring practices.
In an Explosion-proof/flameproof installation, do not remove the transmitter cover
when power is applied to the unit.
Eliminate the risk of ESD discharge prior to dismounting the transmitter head.
Probes may generate an ignition- capable level of electrostatic charge under extreme
conditions. During any type of installation or maintenance in a potentially explosive
atmosphere, the responsible person should make sure that any ESD risks are
eliminated before attempting to separate the probe from the transmitter head.
