XIOLIFT Car-Top Inspection Box 4-in-1 Power Supply Unit RKP220/12PE-19 XOA7072AAG417

XIOLIFT Car-Top Inspection Box 4-in-1 Power Supply Unit RKP220/12PE-19 XOA7072AAG417 is used in elevator car-top inspection operation, maintenance control, and car-top power supply unit applications.

This product is normally installed on or near the elevator car top, depending on the original XIOLIFT elevator configuration. It may be related to inspection operation, maintenance control wiring, car-top electrical connection, and power supply distribution for selected car-top circuits or auxiliary components.

In elevator maintenance and spare parts purchasing, this product may be searched under several different names:

• XIOLIFT Car-Top Inspection Box
• XIOLIFT Car Top Inspection Box
• XIOLIFT 4-in-1 Power Supply Unit
• Elevator Car-Top Inspection Box
• Elevator Inspection Operation Box
• Elevator Car Top Power Supply Unit
• Elevator 4-in-1 Power Supply
• RKP220/12PE-19 Power Supply Unit
• XOA7072AAG417 Inspection Box
• XIOLIFT RKP220/12PE-19 Unit

The main model references for this page are:

• RKP220/12PE-19
• RKP220 12PE 19
• RKP220/12PE
• RKP220/12PE19

• XIOLIFT RKP220/12PE-19
• XIOLIFT XOA7072AAG417
• XIOLIFT Car-Top Inspection Box 4-in-1 Power Supply Unit

These references are useful for search coverage and customer inquiry matching. However, they should not be treated as confirmed interchangeable part numbers. For actual replacement, the old unit label, power input marking, output information, terminal layout, plug direction, inspection box structure, and car-top installation position must be checked before ordering.

Used on the Elevator Car Top

This product should not be described only as a normal elevator inspection box or a simple power supply module.

In a XIOLIFT elevator system, the car-top inspection box is used by technicians during elevator maintenance, inspection running, adjustment, and troubleshooting. When the unit also includes a 4-in-1 power supply function, it may be connected with more than one car-top electrical circuit, depending on the original design.

If the inspection box or power supply unit is damaged, the elevator may show inspection operation problems, unstable car-top circuit power, maintenance control failure, abnormal signal response, damaged terminal connection, or car-top electrical fault. However, these symptoms may also come from wiring harness damage, loose terminals, inspection switch problems, control board faults, power input failure, or previous site modification.

The complete car-top wiring and related control circuit should be checked before confirming that the unit itself is faulty.

RKP220/12PE-19 and XOA7072AAG417 Should Be Checked Together

For this product, the old label is the most important reference.

Some units may show RKP220/12PE-19 on the power supply label or electrical unit marking. Other supplier records, stock labels, or elevator spare parts lists may use XOA7072AAG417 as the part number. These two references should be checked together because customers may search by either the RKP model or the XOA part code.

Before quotation, buyers should confirm:

• complete model number on the old unit label
• whether the label shows RKP220/12PE-19
• whether XOA7072AAG417 appears on the label or previous quotation
• input voltage marking on the old unit
• output voltage and output current information if shown
• terminal layout and wiring direction
• plug type and connector quantity
• inspection switch and button layout, if included
• emergency stop button type, if included
• cable outlet direction
• box size and mounting hole position
• installation position on the elevator car top
• old unit front, side, back, internal wiring, and label photos
• elevator controller or car-top unit information if available

For this product, a clear label photo and terminal wiring photo are more reliable than only writing “4-in-1 power supply unit”.

Where This Unit Is Usually Checked

Maintenance teams may inspect or replace this XIOLIFT car-top inspection box and power supply unit when the elevator has problems such as:

• inspection operation not responding
• unstable car-top power supply
• damaged inspection box housing
• loose wiring plug or terminal
• power output abnormality
• emergency stop or inspection switch fault
• car-top electrical signal failure
• damaged connector after long-term use
• abnormal maintenance operation signal
• old unit needing replacement during elevator repair or modernization

These problems may also be caused by control cabinet wiring, car-top junction wiring, inspection switch damage, output load short circuit, power input failure, controller-side fault, or incorrect wiring after previous maintenance. The unit should be checked together with the related car-top circuit before replacement.

Terminal Layout and Car-Top Wiring Are Critical

Do not replace XIOLIFT Car-Top Inspection Box 4-in-1 Power Supply Unit RKP220/12PE-19 XOA7072AAG417 only by similar box appearance.

Car-top inspection and power supply units may look similar from the outside, but the terminal definition, power output, connector position, cable outlet direction, inspection switch layout, mounting hole position, and internal wiring structure may be different. If the wrong version is installed, the inspection operation may not work correctly, or the car-top circuit may still show power and signal faults after replacement.

Before installation, technicians should compare the old and new units carefully. The label, terminal layout, input and output marking, wiring plug, box size, mounting position, and switch layout should match the original unit. If the terminal definition or output marking is different, the unit should not be forced into use.

For overseas buyers, sending clear photos of the old unit label, internal wiring, terminal area, connector close-up, switch layout, cable outlet, and car-top installation position is the safest way to confirm the correct replacement before shipment.

Practical Procurement Notes

This product is often purchased by elevator maintenance companies, repair teams, and spare parts distributors for XIOLIFT elevator car-top inspection system repair and power supply unit replacement.

For customers in Saudi Arabia, Jordan, Egypt, Iraq, UAE, Kuwait, Brazil, Chile, Spain, and Italy, inquiries for this type of XIOLIFT car-top inspection box often come from maintenance sites where the old unit is already installed on the car top or removed during troubleshooting.

When sending an inquiry, the buyer should provide the complete model number, old label photo, terminal close-up, internal wiring photo, car-top installation position, and quantity required. If the unit will be shipped together with other XIOLIFT elevator spare parts such as inspection switches, car-top boards, power modules, door parts, or control boards, model and wiring confirmation should be completed before packing to reduce the risk of wrong supply.
