!
WARNING – Bodily injury. Carefully review the specifications in this section to select
compliant equipment. Failure to comply with these specifications might create unsafe
conditions, resulting in bodily injury and equipment damage.
3.1.1

Enclosure requirements

The RMC must be installed in an enclosure that complies with the following specifications:
–
The enclosure protects the RMC-100 against shock and impact.
–
For Class I, Division 2, or other outdoor installations, the RMC is installed in an enclosure rated
at least Type 3R, according to the environment.
–
For Class I, Zone 2 installations, the RMC is installed inside an enclosure tested for IP54 in
accordance with IEC 60529 and IEC 60079-15.
3.1.2

Battery and charger requirements

Comply with the following specifications when powering the controller with a battery (battery mode).
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, 30 W or less, or
–
Power source: 14.5 Vdc to 15.5 Vdc, 1.65 A
3.1.3

External power supply requirements

Comply with the following specifications when powering the controller with an external power source
(external power mode):
External power mode operation is +9 Vdc to 30 Vdc, 5 A maximum.
RMC rating for ambient temperature without battery is Ta = -40 °C to +70 °C (-40 °F to 158 °F).
NOTICE – Equipment damage. A battery cannot be used when the RMC is in EXT PWR
mode.
3.2

Location specifications and design

Install an RMC standalone on a DIN rail on an interior wall, in an Xcore enclosure, or in a customer-
supplied enclosure. Xcore enclosures meet the requirements in section
Verify that any non-Xcore customer-suppled enclosures also meet these requirements.
3.2.1

General requirements

The installation location should:
–
Allow access to the enclosure, RMC, power sources, cables and connections
–
Be at a distance that does not exceed the maximum or recommended field wiring lengths for
connections to peripherals or external equipment. Field wiring requirements depend on the type
of connection. See section
If you use a solar panel to provide power, select where and how to install the solar panel outdoors. Do
not place the solar panel where it is in shadow for any part of the day.
3.2.2

Mounting requirements

Mounting surfaces or walls require sufficient strength to support the hanging weight of the RMC
(maximum of 1.816 pounds), the enclosure, and associated equipment to meet the requirements of
IEC715.
3.3

Wiring requirements

Field wiring must meet the following requirements:
3 0 | R MC-1 00 | 2 10 55 5 2MN A E
