External Power Supply Requirements; Wiring Requirements; Unpacking And Inspecting - ABB RMC-100 Startup Manual

2.3

External power supply requirements

When powering the controller with external power (EXT PWR mode), comply with
the following specifications:
— Power supply must be rated as a NEC Class 2 power source. EXT PWR mode
operation is +9 Vdc to 30 Vdc, 5A maximum.
RMC rating for ambient temperature without battery is Ta = -40 °C to +70
–
°C (-40 °F to 158 °F).
WARNING – Equipment damage. A battery can not be used when the
controller is in the EXT PWR mode.
2.4 Location specifications and design
Decide on the location to install the controller. The RMC mounts on a DIN rail. Mount
the DIN rail in an enclosure or on an interior wall that meets the environmental
ratings for the location (see details in section 2.1, Enclosure requirements).
The RMC mounting surface must have sufficient strength to support the hanging
weight of the controller (maximum of 1.816 pounds) and associated equipment to
meet the requirements of IEC715. The installation location should allow sufficient
access to the RMC, power sources, cables, and connections.
If a solar panel is used, decide where and how to install the solar panel outdoors. For
optimum charging, avoid placing the solar panel where it will be in shadows any part
of the day.

Wiring requirements

All wiring connections and screw terminals for power, input ports, output ports, and
communications support 12 AWG to 22 AWG. Wire gauge selection should be based
on the voltage and current requirements of the circuitry as well as the expected
length of the wires. The gauge differs for each application.
Follow local electrical codes when selecting the appropriate wire gauge and type
based on the load current, voltage, signal type, wire length, and indoor or outdoor
application.
WARNING – Equipment damage. Field installation cable and
conductors must be rated greater than 70 °C when installed in an
ambient temperature greater than 60 °C.

3 Unpacking and inspecting

IMPORTANT NOTE: If there is any damage to the shipping carton,
keep it and the packing materials until the contents are inspected and
found to be free of damage.
To unpack the RMC and inspect for damaged, missing or incorrect parts:
1. Inspect the shipping carton for damage.
2. Carefully remove items from the carton.
3. Keep all shipping materials to return any parts.
