DANGER Hazard of electric shock, explosion, or arc flash- Do no remove any other plates or panels while there is power on the system.
- Before any work activity is started it, must be confirmed with measurements directly on the terminals that no power is present.
Failure to follow these instructions will result in death or serious injury. - On the
maintenance bypass cabinet, measure for and verify ABSENCE of voltage
with a multimeter probe through the holes in the transparent plate
for input, bypass, output, neutral, and DC.
DANGER Hazard of electric shock, explosion, or arc flashMeasure for and verify ABSENCE of voltage with a multimeter probe through the holes in the transparent plate for input, bypass, output, and DC.Failure to follow these instructions will result in death or serious injury. - On the UPS, measure for and verify ABSENCE of voltage with a multimeter probe through the holes in the transparent plate for input, bypass, output, neutral, and DC.
- Open the inner door of the UPS.
- On the
UPS, measure for and verify ABSENCE of voltage on each input/bypass/output/DC
busbar before continuing.
DANGER hAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASHMeasure for and verify ABSENCE of voltage on each input/bypass/output/DC busbar before continuing.Failure to follow these instructions will result in death or serious injury. - Remove the busbars and insulator parts that connect the UPS to the maintenance bypass cabinet. See Install Busbars Between the UPS and the Maintenance Bypass Cabinet in Single Mains System or Install Busbars Between the UPS and the Maintenance Bypass Cabinet in Dual Mains System for details. Save all parts for reinstallation.
- Remove the top bracket and the screws in the front that interconnect the UPS and the maintenance bypass cabinet externally. Remove the two special screws that interconnect the UPS and the maintenance bypass cabinet internally. See Interconnect the UPS with the Maintenance Bypass Cabinet for details. Save all parts for reinstallation.
- If
external sync is present: Remove the transparent protection cover
from the external synchronization board 0P4809. The external synchronization
board 0P4809 is located on the rear of the front plate. Disconnect
the signal cables from the external synchronization board 0P4809.
DANGER HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASHCheck for absence of voltage for all three signal terminals on the external synchronization board 0P4809. When the external synchronization cables are installed, the terminals on the external synchronization board 0P4809 may be energized. Disconnect the fuse disconnector device at the source before removing the transparent protection cover.Failure to follow these instructions will result in death or serious injury. - Close the inner door of the UPS and reinstall the screws.
- Disconnect and remove any signal cables from the UPS.
- Remove the seismic front anchoring bracket/front transportation bracket from the UPS and the maintenance bypass cabinet. Save for reinstallation.
- Close and lock the front door of the UPS.
- Raise the feet of the UPS until the casters have full contact with the floor.
- Move
the UPS out of the way of the maintenance bypass cabinet by rolling
it on the casters.
WARNING TIPPING hazard- The casters of the UPS are exclusively for transport on flat, even, hard, and horizontal surfaces.
- The casters of the UPS are intended for transport over short distances (i.e. inside the same building).
- Move at a slow pace and pay close attention on the floor conditions and the balance of the UPS.
Failure to follow these instructions can result in death, serious injury, or equipment damage. - Remove the right side panel from the maintenance bypass cabinet.
- Measure for and verify ABSENCE of voltage on each input/bypass/output/DC busbar in the maintenance bypass cabinet before continuing.
- Remove the power cables from the maintenance bypass cabinet. SeeConnect the Power Cables for details.
- Perform the following on the maintenance bypass cabinet
to reposition parts to their original position. See Prepare for Installation for details.
- Remove the left side panel from the maintenance bypass cabinet and reinstall it on the left side of the UPS.
- Reinstall the right side panel on the maintenance bypass cabinet.
- Reposition the protections cover to their original position on the right side panel.
- Reposition the two rear brackets and the top bracket on the maintenance bypass cabinet to their original position.
- Close and lock the front door of the maintenance bypass cabinet.
- Raise the feet of the maintenance bypass cabinet until the casters have full contact with the floor.
- You can
now move the maintenance bypass cabinet by rolling it over the floor
on the casters.
WARNING TIPPING hazard- The casters of the maintenance bypass cabinet are exclusively for transport on flat, even, hard, and horizontal surfaces.

- Move at a slow pace and pay close attention on the floor conditions and the balance of the maintenance bypass cabinet.
Failure to follow these instructions can result in death, serious injury, or equipment damage. - If present, remove the rear seismic anchoring bracket from the maintenance bypass cabinet and remove the seismic anchors from the floor. Save for reinstallation.
- For transport over longer distances or in conditions
that are not suitable for the casters of the maintenance bypass cabinet:
WARNING Tipping hazardThe maintenance bypass cabinet can tip easily. Take appropriate precautions during handling and preparation for transport/shipment.Failure to follow these instructions can result in death, serious injury, or equipment damage.WARNING TIPPING hazardFor transport over longer distances or in conditions that are not suitable for the casters of the maintenance bypass cabinet, ensure:- that personnel performing the transport have necessary skill and have received adequate training;
- to use appropriate tools to safely lift and transport the maintenance bypass cabinet;
- to protect the product against damage by using appropriate protection (like wrapping or packaging).
Failure to follow these instructions can result in death, serious injury, or equipment damage.Transportation requirements:
-
Mount the maintenance bypass cabinet in a vertical position in the center of a suitable pallet with minimum pallet dimensions: 1000 mm x 1000 mm. The pallet must be suitable for the weight of the maintenance bypass cabinet: 175 kg.
-
Use appropriate means of fixation to mount the maintenance bypass cabinet to the pallet.
-
The original shipping pallet in combination with the original transportation brackets can be reused, if in undamaged condition.
DANGER TIPPING hazard- The maintenance bypass cabinet must be appropriately fixed to the pallet immediately after being placed on the pallet.
- The fixation hardware must be strong enough to withstand vibrations and shocks during loading, transport, and unloading.
Failure to follow these instructions will result in death or serious injury.WARNING Unexpected equipment behaviorDo not lift the maintenance bypass cabinet with a forklift/pallet truck directly on the frame as it may bend or damage the frame.Failure to follow these instructions can result in death, serious injury, or equipment damage. - Perform
one of the following:
- Decommission the maintenance bypass cabinet, OR
- Move the maintenance bypass cabinet to a new location to install it.
- Only for installing the maintenance bypass cabinet in
a new location: Follow the installation manual to install the
maintenance bypass cabinet in the new location. See Installation Procedure for installation overview.
Startup must only be performed by Schneider Electric.
