ATEX Warnings and Conditions of Safe Usage
Power, Input, and Output (I/O) wiring must be in accordance with the authority having jurisdiction
A Warning - Explosion Hazard - When in hazardous locations, turn off power before replacing or wiring modules.
B Warning - Explosion Hazard - Do not disconnect equipment unless power has been switched off or the area is
known to be non-hazardous.
C These products are intended to be mounted in an IP54 enclosure. The devices shall provide external means to
prevent the rated voltage being exceeded by transient disturbances of more than 40%. This device must be used
only with ATEX certified backplanes.
D DO NOT OPEN WHEN ENERGIZED.
Battery Life Advisory
The MVI46, MVI56, MVI56E, MVI69, and MVI71 modules use a rechargeable Lithium Vanadium Pentoxide battery to
backup the real-time clock and CMOS. The battery should last for the life of the module. The module must be
powered for approximately twenty hours before the battery becomes fully charged. After it is fully charged, the battery
provides backup power for the CMOS setup and the real-time clock for approximately 21 days. When the battery is
fully discharged, the module will revert to the default BIOS and clock settings.
Note: The battery is not user replaceable.
