Unpack And Inspect; Basic Hardware Installation; Ground The Controller - ABB RMC-100 User Manual

–
All wiring connections and the screw terminals for power, input/output, and communications
support 12 AWG to 22 AWG. Select the wire gauge according to the voltage and current
requirements of the circuitry. The gauge differs for each application.
–
Follow local electrical codes to select the appropriate wire gauge and type based on the load
current, voltage, signal type, and indoor or outdoor environment.
NOTICE – Equipment damage. Field installation cable and conductors must be rated
greater than 70 °C (158 °F) when installed in an ambient temperature greater than 60 °C
(140 °F).

Unpack and inspect

The RMC and additional parts ship in a specially designed shipping carton with a Quick Start Guide,
Safety and Compliance Sheet, and packing list.
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:
–
Inspect the shipping carton for damage.
–
Carefully remove items from the carton.
–
Keep all shipping materials to return any parts.
–
Compare the packing list with the materials received. Check for any missing or incorrect parts.
–
Inspect each item for damage: RMC exterior, LCD display, optional equipment if purchased.
If there are any missing, incorrect, damaged parts or noticeable defects, call the ABB main office
number on the last page of this manual.

Basic hardware installation

This is an overview of a typical hardware installation. For different installations, call the ABB main
office number on the last page of the manual.
NOTICE – Equipment damage. Perform all the procedures in the order presented in this
section before powering the RMC.
DANGER – Serious damage to health / risk to life. Do not allow the RMC components
to contact a non-insulated tool or be without a proper grounding device. This could create a
static electric discharge resulting in bodily injury and damage to the electronic components.
Use properly insulated tools and wear a grounding strap to eliminate static electricity when
connecting or disconnecting wires.
3.5.1

Ground the controller

The RMC must be mounted on a grounded DIN rail to ground it.
NOTICE – Equipment damage. The DIN rail on which the controller is mounted must be
bonded to an earthing terminal. The bonding conductor must have a cross sectional area of
at least 4 mm2 (12 AWG).
To ground the DIN rail:
1. Screw the DIN rail onto the mounting surface.
2. Attach a grounding wire to the DIN rail.
3. Attach the other end of the wire to an electrical ground.
