The high module current
threshold has been exceeded.
Evaluate the threshold setting. If necessary, adjust
it for your situation.
High Subfeed Current
The high subfeed current
threshold has been exceeded.
Evaluate the threshold setting. If necessary, adjust
it for your situation.
Low Module Current
The low module current
threshold has been exceeded.
Evaluate the threshold setting. If necessary, adjust
it for your situation.
Low Subfeed Current
The low subfeed current
threshold has been exceeded.

The maximum module current
threshold has been exceeded.
Evaluate the threshold setting. If necessary, adjust
it for your situation.
Maximum Subfeed Current
The maximum subfeed current
threshold has been exceeded.
Evaluate the threshold setting. If necessary, adjust
it for your situation.
Minimum Module Current
The minimum module current
threshold has been exceeded.
Evaluate the threshold setting. If necessary, adjust
it for your situation.
Minimum Subfeed Current
The minimum subfeed current
threshold has been exceeded.
Evaluate the threshold setting. If necessary, adjust
it for your situation.
Modular Distribution
Communication
Communication has been lost
with the modular distribution
breakers.
Check the communication cables to ensure they
are properly connected. Contact APC Customer
Support.
Module Breaker Open
A modular circuit breaker is
open.
Check the modular circuit breakers to see if one
has overloaded. Replace if necessary.
