Terminal Block output
Frequency Voltages* L1 N L2**
60Hz 120 / 208 VAC 120VAC Neutral 208VAC
60Hz 120 / 240 VAC 120VAC Neutral 240VAC

* CAUTION: Refer to the nameplate voltage and frequency ratings
affixed to the unit. This power supply was wired for this particular
voltage configuration when it was shipped from the factory.
**Units shipped as 60Hz, single 120V output, do not use L2.
5. RS-232 TERMINAL COMMUNICATION
“MAINTENANCE PARAMETERS” allow you to customize UPS detection
and warning characteristics. Normally, there should be no need to change these
factory settings.
CAUTION: If any of these parameters are changed, it is vital to thoroughly
test the UPS since an improper adjustment can render the unit useless.
Since each parameter is viewed through reference numbers (1 - 16) and
translated into a scale of “reasonable” adjustments, an increase or decrease
of 2 - 3 reference numbers will have a noticeable affect. If you have
questions, contact Alpha prior to making any adjustment.
Fast Detect Lo Ref
Increasing this value will make the UPS more sensitive to a fast, low
amplitude line disturbance (glitch).
Fast Detect Hi Ref
Increasing this value will make the UPS more sensitive to a fast, high
amplitude line disturbance (spike).
Medium Detect Lo Ref
Increasing this value will make the UPS more sensitive to a slow, low
amplitude line disturbance (sag).
Medium Detect Hi Ref
Increasing this value will make the UPS more sensitive to a slow, high
amplitude line disturbance (surge).
Slow Detect Lo Ref
Increasing this value will make the UPS more sensitive to a slow, low
amplitude line disturbance (brownout) by raising the brownout detection
level.
NOTE: The Slow Detect Hys Lo Ref should also be adjusted by the same
amount.
