6. Fuse operation
There is a fuse inside the Zener Barrier that is rated for 40 mA. If the
current at the input to output exceeds 40 mA by an Input or Output
short, the fuse will be blown. Since the fuse is underneath the epoxy, if it
is ever blown the Zener Barrier will need to be completely replaced. It
cannot be fixed and the fuse cannot be replaced.
7. Cleaning and decontamination
For cleaning, turn off the power to the unit and clean with a damp cloth.
Make sure that the unit is dry before turning the power back on.
DO NOT USE SOLVENTS .
Solvents should not be used, as they may harm the painted finish. Never
open the cover of the enclosure while power is applied to the system
due to the danger of explosion. Never connect or disconnect the wires
inside the enclosure with power applied. Always assume that the
hazardous atmosphere is present.
