Module Status And Diagnostics; Connecting The Expansion Power Supply To The Main Frame Power Supply; Connecting The Expansion Power Supply To Ground - Motorola ACE3600 RTU Owner's Manual

Module Status and Diagnostics

Detailed module status and diagnostics information can be retrieved via the main CPU using
the STS Hardware Test utility. For more details, see the Hardware Test section of the
ACE3600 STS User Guide.
Module Warnings and Errors
Power supply module warnings and errors are logged in the main frame CPU memory. The
RTU error logger information can be retrieved using the STS Error Logger utility. For more
details, see the Error Logger section of the ACE3600 STS User Guide.
Connecting the Expansion Power Supply to the Main Frame Power
Supply
The expansion power supply can only be connected to the power supply on the ACE3600 RTU
main frame and to other expansion power supply modules.
For instructions on connecting the expansion power supply, see the Connecting the Expansion
Power Supply to the Main Frame Power Supply section of the Installation chapter above.
If all the power supplies on I/O expansion frames are attached via DC cable to the power
supply on the previous I/O expansion frame in a daisy-chain manner, the main power supply
controls the entire RTU. This enables the user to turn off the entire RTU simply by turning off
the main power supply.
If the main power supply does not control all other power supplies in the RTU (e.g. when the
total power consumption required does not allow all frames to be daisy chained), it is
recommended that the main power provided to the power supplies be connected to a single
external on/off power switch.
All power and ground connections must be in accordance with local standards and
laws.

Connecting the Expansion Power Supply to Ground

The power supply on each expansion frame must be connected to the grounding strip of its
frame. For important warnings on ground connections, see Connecting Power and Ground in
the Installation chapter above.
Connect the terminal ring on the (green/yellow) ground wire of the DC cable
(FKN8559A/3002360C26) to the grounding strip located on the frame beneath the power
supply slot. Make sure to tighten the screw firmly. See Figure 19-3 below.
