3.7.1.7 The UPS has successfully passed the start-up procedure. The UPS will
charge the batteries whenever the UPS is connected to an AC source and
there is an acceptable AC voltage present. It is recommended that the
UPS's batteries be charged for a minimum of 8-hours before use. However
the UPS may be used immediately, but the “On-Battery” runtime maybe
less than normally expected.
NOTE:
If the UPS is going to be out of
service or stored for a prolonged period of time, the batteries must be
recharged for at least 12-hours every 3 months.
3.7.2 Startup in Battery Mode (Cold Start)
3.7.2.1 Switch the UPS’s input circuit breaker (on the rear panel) to the On
position.
3.7.2.2 Press and hold the UPS On Switch (on the front panel)
for
approximately 3-seconds, then release, the audible alarm will sound 2-
beeps. The LCD display will scroll from drawing A to drawing G this will
take approximately 10-seconds.
3.7.2.3 During this 10-seconds press and hold the UPS On Switch again
for
approximately 3-seconds, then release, the audible alarm will sound 2-
beeps. The LCD display will change from drawing G to drawing H, the
UPS will be in self-test mode. The UPS will provide an output within
approximately 1-minute, and then the LCD display will display drawing I. If
the UPS On switch was not pressed within the 10-seconds, the UPS will
automatically turn off. You will have to repeat the above steps again.
G
* It shows “Off”, which means the UPS pre-start is successful.
H
* It shows the Utility input is “0VAC”.
31
I
* It shows the UPS is providing power to the “load”.
3.7.3 Measured Values detected by UPS
3.7.3.1 If you would like to check the measured values detected by the UPS,
please use the scroll down
and scroll up
keypads. When you use
scroll down keypad, the LCD display will display the drawings in the
following order:
Drawing C (Voltage from Utility Input)
Drawing I1 (Voltage from Bypass Input)
Drawing J (Frequency from Utility Input)
Drawing K (Frequency from Bypass Input)
Drawing L (UPS Output Voltage)
Drawing M (UPS Output Frequency)
Drawing N (UPS Output Load %)
Drawing O (UPS Battery Voltage)
Drawing P (UPS Internal Temperature)
I1
* It shows the input voltage from the Bypass Input.
J
* It shows the input frequency from the Utility Input.
