GROUNDING THE D.20 RIO
CHAPTER 2: INSTALLING THE D.20 RIO
Grounding the D.20 RIO
Surge and noise suppression components used on the D.20 RIO are designed to prevent
nuisance operation and damage to internal components. To ensure correct protective
operation, the earth ground stud on the D.20 RIO must be connected to a low impedance
ground using a braided cable or heavy solid copper conductor (12 AWG green/yellow wire
is recommended, GE part number 970-0182).
When making ground connections, ensure that all surfaces that are used for grounding
are free of dirt, residue and corrosion.
Torque settings
The recommended tool torque settings for zinc-plated mounting screws are:
•
22.2 in-lb [2.50 Nm] for 10-32 UNF screws
•
31.0 in-lb [3.51 Nm] for 12-24 UNC screws
•
18.1 in-lb [2.04 Nm] for M5 x 0.5 [8 mm] screws
•
33.3 in-lb [3.76 Nm] for M6 x 0.5 [8 mm] screws
Connecting the power supply
The D.20 RIO can be supplied power by a 24 VDC (GE part number 580-3483) or 48 VDC (GE
part number 580-3484) DIN rail mounted power supply. One of these power supplies must
be used to ensure compliance with the standards referenced.
Table 3: D.20 RIO Power Input Requirements
Review the manufacturer-provided documentation that accompanies your power
supply unit before installation. Ensure that you are in compliance with all safety
instructions provided.
Any voltage input supplied to the D.20 RIO is also output through the
Aux
connectors on
the power supply connections block.
The Aux output must not be directly or indirectly connected to another power source.
When the Aux output is connected to a device with two input power sources, a protection
circuit must be used on the Aux output to prevent any voltage feedback. Failure to do so
can negatively impact system operation or damage the power source equipment.
