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 and load.

DANGER
Hazard of electric shock, explosion, or arc flash Measure for and verify ABSENCE of voltage with a multimeter probe through the holes in the transparent plate for input/bypass and load. 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 on each busbar or terminal for input, bypass, output, neutral, and DC. See UPS installation manual for details.

DANGER
hAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH Measure for and verify ABSENCE of voltage on each busbar or terminal for input/bypass/output/neutral/DC busbar before continuing. Failure to follow these instructions will result in death or serious injury.

On the UPS, disconnect and remove the internal power cables coming from the maintenance bypass cabinet. See the UPS installation manual and Connect the Internal Power Cables for details. Save all parts for reinstallation.

Remove the screws in the front that interconnect the UPS and the maintenance bypass cabinet externally. See Interconnect the UPS and the Maintenance Bypass Cabinet for details. Save all parts for reinstallation.

Reinstall the front panel on 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.

For transport over longer distances or in conditions that are not suitable for the casters of the maintenance bypass cabinet:

WARNING
TIPPING hazard For 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.

WARNING

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: ? mm x ? mm. The pallet must be suitable for the weight of the maintenance bypass cabinet: 110-120 kg (243-265 lbs).
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 behavior Do 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 Top Cable Entry or Installation Procedure for Bottom Cable Entry for installation overview. Startup must only be performed by Schneider Electric.

DANGER
hAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH Startup must only be performed by Schneider Electric. Failure to follow these instructions will result in death or serious injury.
