1.0 Introduction
The SDU AC - A Series is a compact, “Off-Line” DIN rail mountable UPS, which provides conditioned power to
sensitive electronic equipment in an industrial environment. It supplies connected equipment with stepped
approximation to sinewave input during power outage to simulate the power generated by the utility.
Figure 1: Transition to Back-Up Mode Due to Power Outage
AC Mode AC Loss
of Power Battery Mode
Input voltage range is 80% to 110% (ideal protection for the critical connected loads). Battery charging occurs
automatically when ac power is applied, no need to switch ON the UPS. When power fails, the UPS can be
automatically turned OFF, as long as the connected loads are not operating to save the battery energy. The
SDU also includes an automatic self-test feature to test the UPS function and battery. If the battery is no longer
useful, the unit will sound an alarm and an LED indicator will illuminate
This SDU AC - A Series has a communication port that can accommodate an optional communication card.
Contact a SolaHD Technical Support representative for a list of currently available communication cards.

!WARNING
Risk of electric shock, disconnect AC main power source before wiring. Ensure proper grounding
4. I/O Wiring: Make sure the UPS and the AC Supply is OFF (disconnected) before installation. Wire the
UPS terminals with 90 °C rated copper wire according to the table below. Connect the AC input ground
terminal to the main supply ground. Connect line in neutral supply conductors. Connect the loads to the
output hardwire connector. Verify proper wiring connections then apply power to the UPS.
Reference Figure 2.
Wire Gauge 10-18 AWG
Screw Torque 9 lb-in. (101.7 N-cm)
5. Internal Battery: Charge the UPS battery for a minimum of 8 hours before initial use. The UPS charges
its battery whether the UPS is on or off, when it is connected to AC power.
6. Warning Label: Apply the provided electrical shock warning label to the panel, making it clearly visible
to the user.
Risk of electrical shock—
hazardous live parts inside this

!WARNING
Remote ON/OFF is grounded to the UPS internal signal ground so it should be isolated from the
chassis ground to prevent any ground potentials that may cause a unit malfunction or damage. In
addition, isolate the Remote ON/OFF wiring away from high current, high voltage, and high frequency
components to prevent any magnetically coupled noise on the Remote On/Off connections.

7.0 Operating Instructions
7.1 TURNING ON THE UPS
• Press the POWER ON/OFF/TEST button for more than 2 second until you hear the “3 quick beeps” and
the LEDs turn ON.
Note: If utility power is not present, the UPS will be in back-up mode. The load will be powered from the
internal batteries until the discharge point is reached.
7.2 TURNING OFF THE UPS
• Hold the POWER ON/OFF/TEST button until the LEDs turn OFF.
7.3 ALARM
• Factory default setting is alarm enabled.
• To enable/disable Alarm:
• When the UPS is in back-up mode, press the POWER ON/OFF/TEST button for at least 1 second to silence
the alarm (this function is disabled when the UPS status is either LOW BATTERY or OVERLOAD MODE). To
re-enable the alarm, press the POWER ON/OFF/TEST button for at least 1 second. Additionally, you can
enable/disable the alarm via UPSMON Software.
7.4 SELF TEST
• ThisUPShasaselfdiagnosticfeaturethatveriesboththeoperationoftheUPSandtheconditionofthe
battery.
• In AC mode, press and release the POWER ON/OFF/TEST button for at least 1 second to perform a self-
test. During the self-test, the UPS momentarily operates in back-up mode (YELLOW LED will illuminate
momentarily then goes back to GREEN). If the UPS passes the self-test, it returns to AC mode.
• If the YELLOW LED does not illuminate momentarily, please contact SolaHD Technical Support or your
local SolaHD distributor for a replacement.
• Additionally a self-test can be ran via UPSMON software.
7.5 GREEN MODE
• Factory default setting is Green Mode disabled.
• Green Mode is a feature to reserve battery energy in low load conditions. In back-up mode and if the
load level is less than approximately 2% ~ 4% (or 60W), the UPS will shutdown to save battery in 180
seconds. If power is restored within 180 seconds, the UPS will return to AC mode.
• Green Mode Enable/Disable:
• Green Mode can be ENABLED or DISABLED by pressing the POWER ON/OFF/TEST at start-up per TABLE 2:
Green Mode Alarm Signal
Enabled press POWER ON/OFF/TEST button and release until “3 beeps” are heard
Disabled press POWER ON/OFF/TEST button and release until the “2 beeps” are heard

This 3 minute window (or maximum run time depending on loading) allows the user to shut off or place
equipment into safe mode.
7.7 REMOTE ON/OFF
• Allows the user to perform remote power ON/OFF functions using a switch on terminals

disconnect cables connected to the UPS to avoid unnecessary draining of the battery.
Extended Storage
During extended storage in environments where the ambient temperature is:
-15 °C to +30 °C (+5 °F to +86 °F), charge the UPS battery every six months.
During extended storage in environments where the ambient temperature is:
+30 °C to +45 °C (+86 °F to +113 °F), charge the UPS battery every three months.
