To maintain hazardous location certifications, you can only replace components in the
field with the exact same part so that the model string on the data plate remains correct.
This means you cannot add any hardware not reflected in the model string or upgrade a
hardware component to a newer version; any such upgrades are prohibited and void the
hazardous location certification. This chapter describes the service tasks that everyone
needs to know such as replacing batteries or installing a firmware upgrade. Any
replacement not covered in this chapter can only be performed at an Emerson-authorized
repair facility.
Important
Only use batteries supplied with the RTU or sold by Emerson Remote Energy and
Transportation Solutions as spare parts for this RTU. If you substitute a battery you obtain
elsewhere you will void your hazardous location certification unless it is the identical part
from the same manufacturer as that supplied with the RTU from Emerson.
EXPLOSION HAZARD - MAY CAUSE DEATH
Ensure the RTU is in a non-hazardous area. Never open the enclosure in a hazardous
area.
EXPLOSION HAZARD - MAY CAUSE DEATH
Do not disconnect equipment unless power has been removed or the area is known to
be non-hazardous.
