Power Led - ESI IVX C-Class Installation Manual

Hardware overview/installation
Grounding instructions
System grounding (supplemental ground) is as follows:
• The conductor wires can be no smaller than the ungrounded branch-circuit supply conductors
(usually 16-gauge or larger).
• Acceptable wire: bare or covered with green (or green-and-yellow-striped) jacket.
• Conductors (and power receptacles) shall connect to earth ground at the service equipment (usually
a cold water pipe or copper ground rod).
• The supplemental ground must: be used regardless of power cord ground, be connected to the
ground lug on the bottom of the IVX cabinet, and retain ground connection when IVX power supply
module is unplugged.
Note: IVX C-Class system lines are protected against a 10 KV surge only if the earth ground procedures
described above are followed.
Power
The system cabinet requires a 120 VAC outlet (if possible, a dedicated outlet). Use only the Class-2
power supply module provided. A clean, isolated power source in conjunction with a UPS is
STRONGLY recommended. The system draws a maximum of 25 watts.
If AC power is interrupted, the system will drop all connections. When power is restored, the system
will resume normal operation in approximately one minute, having retained its full programming and
clock setting.
UPS
For system protection and to maintain uninterrupted operation, an uninterruptible power supply is
STRONGLY recommended. A UPS rated for 200 VA will provide approximately two hours of
uninterrupted service for an IVX C-Class system.
LED functions
The unit's various LEDs are designed to provide visual feedback as follows:

Power LED

The Power LED is located on the top-right side of the cabinet and is illuminated when power is being
applied to the system. This LED blinks periodically to indicate that the main processor is operational.
Memory Transfer LED
This LED is located inside the cabinet in the center of the main board. It serves as a diagnostic aid by
flashing as data is transferred to and from the Memory Module.
