SHOR
Salicru UPS SHOR: inverter fault from output short circuit
Risk level
High
Professional inspection is recommended.
Urgency
Immediate
Quick answer
Fault code SHOR on a Salicru SLC TWIN PRO2 LCD panel (or the Output short-circuited fault code on SPS SOHO+) warns of an inverter short caused by a short circuit on the UPS output or in connected loads.
Safety first
Stop and check this first
- Never turn the UPS back on before confirming the short circuit is removed and never open the cabinet: Salicru warns that a UPS is an electrical generator carrying hazardous internal voltages even when disconnected from the mains.
Safe checks you can perform
- Turn off the UPS and disconnect all loads from the output sockets
- Do not restart with suspect loads and observe the unloaded display status
- Compile the system details required by Salicru Technical Service and Support
Leave these tasks to a qualified professional
- Do not attempt this professional task: Electrical testing of disconnected loads and UPS output for short circuits
- Do not attempt this professional task: Inverter and internal fault inspection by Salicru T.S.S.

These are the steps they must carry out and show you. Tick them as they work: if steps are skipped, do not accept a part swap.
These are not instructions for opening or handling the equipment yourself. They are the checks that should support a technical conclusion.
Electrical testing of disconnected loads and UPS output for short circuits
What they doWith all loads removed and the UPS turned off, a qualified technician tests the disconnected equipment, cords, and output wiring to locate and clear the short circuit before the UPS is switched back on.
They must show youthe continuity or insulation test identifying the shorted load or cable and confirming the output circuit is clear.
In writingwhich disconnected load or cord caused the short circuit and verification that the output is clear before restart.
Inverter and internal fault inspection by Salicru T.S.S.
What they doIf fault code SHOR or the red fault alarm remains active with all output loads disconnected, Salicru Technical Service and Support (T.S.S.) inspects the inverter stage for internal faults.
They must show youunloaded inverter verification on the LCD panel or the official Salicru T.S.S. service report.
In writingUPS model and serial number, inverter test findings, and T.S.S. repair or replacement documentation.

Nothing has been shown yet. Do not accept a part swap based on the code alone.
Follow these steps
Note: Follow the documented order. An error code identifies the affected system, but it does not prove by itself which part has failed.
Turn off the UPS and disconnect all loads from the output sockets
- Who:
- you, following the immediate action specified in Salicru's troubleshooting table.
- How:
- switch off the UPS from its front control panel and unplug every device and power cord connected to the output sockets.
- Result that matters:
- isolate the UPS output completely from any external equipment that may have shorted.
- If you spot a damaged power cord or a device that triggered SHOR the moment it was plugged in:
- keep that item permanently disconnected from the UPS.
- If all external cords and devices look intact:
- leave them unplugged while verifying that the short circuit has been removed.
- Evidence to keep:
- list of all loads that were plugged into the UPS output when SHOR appeared.

Do not restart with suspect loads and observe the unloaded display status
- Who:
- you, before attempting to turn the Salicru UPS back on.
- How:
- keep suspect loads and prohibited devices (such as laser printers or scanners) unplugged; check whether an SPS SOHO+ restarts cleanly once the shorted load is removed or whether an SLC TWIN PRO2 requires professional verification before restarting.
- Result that matters:
- comply with Salicru's requirement to ensure the short circuit is removed and the UPS has no internal faults before turning it on again.
- If on an SPS SOHO+ unit, disconnecting the short-circuited load and restarting restores normal Line mode:
- leave the faulty load disconnected.
- If SHOR persists with all loads unplugged or you cannot confirm the output is free of a short:
- keep the UPS off and contact a qualified technician or Salicru T.S.S.
- Evidence to keep:
- LCD fault screen status with all output receptacles disconnected.

Compile the system details required by Salicru Technical Service and Support
- Who:
- you, recording the nameplate and incident information listed in the Salicru manual.
- How:
- note the UPS model and serial number, the date SHOR occurred, the complete LCD panel status and alarm state, the power supply condition and connected load details, and the ambient temperature and cooling conditions.
- Result that matters:
- have all required diagnostic details ready for Salicru Technical Service and Support (T.S.S.) if the fault persists.
- If T.S.S. intervention is needed:
- avoid any unauthorized repair attempt, which Salicru excludes from warranty coverage.
- If an electrician inspects the downstream loads first:
- retain their report identifying the shorted appliance or cable.
- Evidence to keep:
- UPS model, serial number, date of fault, and description of the connected load and LCD indications.

What it means
On Salicru SLC TWIN PRO2 units, the LCD screen displays fault code SHOR (Inverter short) when an output short circuit is detected; similarly, Salicru SPS SOHO+ models show an Output short-circuited LCD fault code, and SPS.ONE units indicate a UPS fault with a solid red LED and constant beeping. Salicru's troubleshooting procedure requires removing all loads, turning off the UPS, checking whether the UPS output or loads are short-circuited, and ensuring both that the short is cleared and that the UPS has no internal faults before turning it on again. Code SHOR alone never proves the inverter is permanently damaged until external loads are isolated.
Warnings and stop conditions
- Highsource verified
Never turn the UPS back on before confirming the short circuit is removed and never open the cabinet: Salicru warns that a UPS is an electrical generator carrying hazardous internal voltages even when disconnected from the mains.

Symptoms and causes
Probable causes · in order
- Short circuit in a connected load or output power cordCommon
A shorted power supply or damaged cord plugged into the UPS output receptacles creates an output short circuit that triggers SHOR or the Output short-circuited fault code.
Evidence: Manual de usuario SAI SLC TWIN PRO2 (0.7.. 3 kVA) · User Manual UPS SLC TWIN PRO2 (0.7.. 3 kVA) · Manual de usuario SAI SPS serie SOHO+ (EL310A00)
- Short circuit on the UPS output wiring or socketsPossible
Salicru's troubleshooting table lists an output short circuit on the UPS output side as a direct cause of the SHOR fault code.

- Internal fault in the UPS inverter stagePossible
If SHOR or the constant fault alarm remains present after all external loads are unplugged, an internal inverter fault may prevent the UPS from restarting safely.
