Field Serviceability
The 825-P firmware can be upgraded in the field; refer to
Firmware Upgrade Instructions. You know when a self-test failure has occurred
by monitoring the front-panel messages. By using the metering functions, you
know if the analog front-end (not monitored by relay self-test) is functional.
Refer to
: Testing and Troubleshooting for detailed testing and
troubleshooting information. The only two components that can be replaced in
the field are the power supply fuse and the real-time clock battery. A lithium
battery powers the clock (date and time) if the external power source is lost or
removed. The battery retains the thermal memory for the thermal overload
function when the power source is lost or removed. The battery is a 3V lithium
coin cell, Rayovac® BR2335 or equivalent. At room temperature (25°C), the
battery operates nominally for ten years at rated load. When the relay is powered
from an external source, the battery experiences a low self-discharge rate. Thus,
battery life can extend well beyond ten years. The battery cannot be recharged.
ATTENTION:
Disconnect or de-energize all external connections before opening this
device. Contact with hazardous voltages and currents inside this device can cause
electrical shock that can lead to injury or death. Equipment components are sensitive to
electrostatic discharge (ESD). Undetectable permanent damage can result if you do not
use proper ESD procedures. Ground yourself, your work surface, and this equipment,
before removing any cover from this equipment. If your facility is not equipped to work
with these components, contact Rockwell Automation about returning this device and
related Rockwell Automation equipment for service.
