For DC units:
Use the DC power cord assembly provided.
Only connect the DC power cord
after
all I/O connections are complete. The
power supply automatically senses and adapts to any input from –40 through –
60 V DC.
Connect this equipment directly to the DC supply system earthing electrode
conductor or to a bonding jumper from an earthing terminal bar or bus to which
the DC supply system earthing electrode is connected.
Locate this equipment in the same immediate area (such as adjacent cabinets)
as any other equipment that has a connection between the earthed conductor of
the same DC supply circuit and the earthing conductor, and also the point of
earthing of the DC system. Do not earth the DC system elsewhere.
Place the DC supply source within the same premises as the equipment.
Do not position switching or disconnecting devices in the earthed circuit
conductor between the DC source and the point of connection of the earthing
electrode conductor.
CAUTION
This unit has up to two (2) 100 –240 V
or two (2) –48 V
input power feeders.
Disconnecting less than the maximum will not de-energize the system. To reduce the
risk of injury, disconnect all power feeders when removing power to the system.
Confirming APEX1000 Power-on Sequencing
When power is applied, the STATUS LED indicates APEX1000 sequencing as follows:
LED Color
Condition
Blinking Red
Initially, the STATUS LED blinks red to indicate the APEX1000 is
performing a memory test.
Blinking Yellow
Sequentially, the STATUS LED blinks yellow to indicate a successful
memory test completion and boot code execution.
Blinking Green
The STATUS LED then starts blinking green to indicate that the
application code is configuring the APEX1000 for operation.
Blinking Red and Green
Finally, all of the LEDs blink red, and then green.
Solid Green
When the STATUS LED is solid green, it indicates the unit is
operational.

If the STATUS LED is yellow or solid red, but the error does not prevent activating
the APEX1000 EM, proceed to
•
If the STATUS LED is yellow or solid red and the error precludes activating the
APEX1000 EM to perform the APEX verification, reference
for help
with many common problems.
