Minuteman Continuous Power Series UPS
Top LED is red
:
Line voltage(s) is above acceptable limits. UPS on battery
power.
Middle LED is green:
Line voltage(s) is at acceptable levels. If the LED is
not lit the UPS is on battery power.
Middle LED flashes green:
A site wiring fault is detected. Consult
Troubleshooting Guide for details.
Bottom LED is red:
Line voltage(s) is below acceptable input level. UPS
is on battery power.
All three AC Input LEDs are on:
Input frequency is outside the bypass
range but line voltage is within acceptable range. See Configuring the
UPS later in this section for instructions on changing frequency range.
Battery Level LEDs
The battery level LEDs indicate the amount of approximate charge in the
battery. Adding external batteries will increase backup-times.
Bottom LED is red:
Indicates impending low battery. The UPS has 2-5
minutes battery backup left before shutdown.
Remaining Four LEDs:
4 LEDs are green: >90% charge
Load LEDs
There are two columns of LEDs above the load icon that indicate load levels.
Load level is based on RMS current or watts, whichever is greater. On single-
phase models, the first and second columns indicate the same load informa-
tion. On two-phase models the first column shows the amount of power drawn
from line 1 and the second column shows the amount drawn from line 2.
Top LED is red:
Overload.
Load is >100% of total load capacity.
4 LEDs are green:
75-100% of total load capacity
3 LEDs are green:
50-75% of total load capacity
2 LEDs are green:
25-50% of total load capacity
1 LED is green:
5-25% of total load capacity
Bypass LED
The bypass LED is red when the UPS is in bypass mode. This LED must be
on before the MBS switch can be used.
Battery Service LED
The Battery service LED is solid red when the battery requires service. See the
Troubleshooting Guide for details.
