Live Swap: Add, Remove, or Replace a Power Module

NOTE: This UPS has been designed and evaluated for power module insertion and removal in any operation mode: Live Swap . This page specifies manufacturer’s instructions for how to perform Live Swap .
NOTE: Incident energy is <1.2 cal/cm2 when installed and first startup commissioned in accordance with product instructions. Incident energy is measured 200 mm (8 in) from cabinet front.


  • Electrical equipment should be installed, operated, serviced, maintained, replaced, or have similar work carried out on it only by suitably qualified, trained, experienced, and competent personnel who hold any necessary authorizations (e.g. licenses, permits or certifications) to perform such work. All work must be carried out in a way that does not give rise to danger and using appropriate personal protective equipment (PPE). 

  • User must ensure compliance with the manufacturer’s instructions and user manual and with all applicable laws, regulations, standards, and guidance when using this equipment and carrying out work or permitting work to be carried out on or near electrical equipment.

  • Neither Schneider Electric nor any of its affiliates shall be liable for any claims, costs, losses, damages, death, or injuries arising out of the improper use of this equipment or any failure to comply with any of the above requirements.

Hazard of electric shock, explosion, or arc flash
  • Verify that the UPS has the Live Swap label present.
  • If no Live Swap label is present on the UPS, contact Schneider Electric for power module replacement.
  • Apply appropriate personal protective equipment (PPE) and follow safe electrical work practices.
  • Persons must not be present behind the UPS during this procedure.
  • Insertion or removal of power modules must only be performed by qualified personnel knowledgeable of electrical work and the required precautions. Keep unqualified personnel away.
  • This procedure requires opening the front door. All other doors and covers must remain closed and secured during this procedure.
  • Verify that the UPS is secured against movement before performing this procedure.
  • If evidence of poor maintenance or poor installation is observed, do not proceed with this procedure.
  • Do not install power modules which have been accidentally dropped, broken, flooded, contaminated, infested, or damaged in any way.
  • Do not install power modules which are of unknown operational state.
  • Keep a minimum distance of 200 mm (8 in) from the cabinet front while the system is energized.
  • Do not use any tools inside the empty power module slot.
  • Do not reach into the empty power module slot.
Failure to follow these instructions will result in death or serious injury.
risk of equipment damage
  • Store the power modules at an ambient temperature of -15 to 40 °C (5 to 104 °F), 10-80% non-condensing humidity.
  • Store the power modules in their original protective packaging.
Failure to follow these instructions can result in death, serious injury, or equipment damage.
Heavy load
Power modules are heavy and require two persons to lift.
  • 20 kW power module weighs 25 kg (55 lbs).
  • 50 kW power module weighs 38 kg (84 lbs).
Failure to follow these instructions can result in injury or equipment damage.
  • Check and verify that the remaining power modules can support the load before removing a power module from the UPS.

  • Increasing or decreasing the number of installed power modules in the UPS can only be performed on the scalable UPS models (GVSUPS50K150HS, GVSUPS50K150GS, or GVSUPS25K75FS). Check and verify that the installation is correctly sized for the increase in power rating before installing more power modules in the UPS. Incorrect sizing of the installation can result in an installation overload. See the installation manual for requirements for upstream and downstream protection, cable sizes, etc.

  • On all non-scalable UPS models, only replacement of already present power modules can be performed.

NOTE: The procedure shows the power module installed in a horizontal position in the UPS. The procedure will be the same for power modules installed in a vertical position in the UPS.
  1. Remove a power module:
    1. Remove the screws and push the unlock switch.
    2. Pull the power module halfway out. A locking mechanism prevents the power module from being pulled all the way out.
    3. Release the lock by pressing the release button on both sides of the power module and remove the power module.
    4. Only on scalable UPS models: If no replacement power module will be installed: Install a filler plate in front of the empty power module slot.
  2. Install a power module:
    1. Only on scalable UPS models: To install an additional power module , remove the filler plate from the empty power module slot. Save the filler plate for future use.
    2. Push the power module into the slot. The enable mechanism will latch when the power module is correctly inserted.
    3. Install the provided screws in the sides of the power module.
    The power module will perform a self-test, automatically reconfigure according to the system, and then go online.
Hazard of electric shock, explosion, or arc flash
All power module slots must have either a power module or a filler plate installed.
Failure to follow these instructions will result in death or serious injury.
