Installing the RMC requires that customer-supplied enclosures, power sources,
wiring, and location comply with the specifications described in this section.
WARNING – Bodily injury
. Carefully review the specifications listed in
this section to select compliant equipment.
Failure to comply with these specifications may create unsafe
conditions, resulting in bodily injury and equipment damage.
2.1 Enclosure
requirements
The RMC must be installed in an enclosure complying with the following
specifications:
— Enclosure must protect the RMC-100 against shock and impact.
— For Class I, Division 2, or other outdoor installations, the RMC-100 shall be
installed in an enclosure rated at least Type 3R, according to the environment.
— For Class I, Zone 2 installations, the RMC-100 shall be installed inside an

2.2 Battery and charger requirements
When powering the controller with a battery (battery mode), comply with the
following specifications:
— Battery
specifications:
–
Nominal 12 Vdc Sealed Lead Acid
–
RMC rating for ambient temperature with battery is Ta = -40 °C to +60 °C
(-40 °F to 140 °F)
— Battery charger specifications:
–
Solar panel must be nominal 12 Vdc, 30W or less, or
–
