Q3: How to install the AGPS retrofit kit? Is commissioning needed after installation? Can I install it myself?

A: Installation of the AGPS retrofit kit requires certain professional knowledge and skills, recommended to be performed by professional engineers trained in ABB drives.

General installation steps (refer to ABB installation manual for specifics):

Preparation: Confirm drive is completely de-energized (disconnect main power and control power); wait for DC bus capacitors to fully discharge (usually wait 15+ minutes, confirm DC bus voltage drops to safe level); prepare new AGPS retrofit kit (confirm model 68766508 matches R8i frame); prepare tools (screwdriver, hex wrench, anti-static wrist strap, multimeter); read ABB official installation instructions.
Remove drive cover: Open drive housing cover, locate the designated AGPS board installation position (usually near IGBT driver board or power module area).
Install AGPS-21C board: Install AGPS-21C power supply board to designated position, fix with screws; connect power input, output, and control signal ribbon cables/plugs on the board, confirm firm connection and correct orientation.
Connect safety input circuit: According to "Prevention of Unexpected Start-up" function safety design, connect safety input signals (e.g. safety door switch, emergency stop button, maintenance switch) to corresponding terminals of AGPS board or drive control board.
Check and close: Check all wiring correct, no looseness, no leftover tools or foreign objects; close drive housing cover.
Power on and parameter setting: Restore drive power; enter drive parameter setting menu, enable "Prevention of Unexpected Start-up" function (+Q950 related parameters), configure safety input logic and response mode.
Safety function verification: According to ABB verification procedure, test that "Prevention of Unexpected Start-up" function responds correctly under various safety conditions (e.g. whether drive cannot start when safety input disconnected, whether manual reset is required to start after safety conditions restored).

Is commissioning needed after installation? Must commission and verify. After AGPS retrofit kit installation is complete, need to:

Perform drive parameter setting, enable +Q950 function and configure related parameters
Perform safety function verification test, confirm "Prevention of Unexpected Start-up" function responds correctly under various operating conditions
Record verification results, form safety function verification documentation (meeting functional safety standard documentation requirements)
If necessary, perform overall drive function test, confirm drive operates normally after retrofit

Can I install it myself?

If you or your maintenance personnel have received ABB ACS800 drive maintenance training, are familiar with drive internal structure, electrical principles, and parameter settings, and have appropriate tools and safety operation knowledge — you can install it yourself.
If no experience — strongly recommend contacting ABB official service or professional drive maintenance service provider for installation and commissioning, ensuring safety function is correctly implemented.
Safety notes:
- Before installation, must completely de-energize and wait for capacitor discharge (at least 15 minutes), use multimeter to confirm DC bus voltage has dropped to safe level
- Wear anti-static wrist strap to avoid electrostatic damage to AGPS board electronics
- Safety function involves personnel safety, installation and verification must be strictly performed according to ABB official documentation
- Retrofit of explosion-proof/special environment drives must comply with relevant regulations, performed by qualified personnel

Q4: My ACS800 drive already has +Q950 function, do I still need to buy this kit?

A: If your ACS800 drive already has +Q950 "Prevention of Unexpected Start-up" function configured at factory, then the drive should already have an AGPS board installed internally, you do not need to buy this retrofit kit.

When do you need to buy 68766508?

Drive did not have +Q950 function at factory, needs field retrofit: This is the most common situation. Already installed ACS800 R8i drives did not have "Prevention of Unexpected Start-up" function at factory, due to safety compliance requirement upgrade (e.g. EU Machinery Directive, functional safety standards, customer safety audit requirements), need to add this function on site, at this time purchase AGPS retrofit kit for retrofit.
Original AGPS board damaged, needs replacement: Drive already has +Q950 function, but internal AGPS board has failed (e.g. abnormal power output, safety function failure, board burnt, etc.), needs AGPS board replacement. At this time can purchase the entire retrofit kit, or separately purchase AGPS-21C board (Contact via email for confirmation whether standalone board part number is available).
Spare parts reserve: For critical application ACS800 drives, to reduce failure downtime, reserve AGPS board as emergency spare part.

How to confirm whether drive already has +Q950 function?

Check drive nameplate/option code: If drive nameplate or ordering code includes "+Q950", it means the function was configured at factory.
Check drive parameters: Enter drive parameter menu, check whether +Q950 related parameter group exists, and whether the function is enabled.
Check drive internal: Open drive housing, check whether AGPS board is already installed (board printed with AGPS-21C etc. identification).
Check drive documentation: Review drive factory test report, configuration list, or user manual, confirm option configuration.

If uncertain, contact via email for confirmation, provide complete drive model, ordering code, and nameplate photo, we can help confirm whether +Q950 function is already configured, and whether retrofit kit needs to be purchased.

Notes:

68766508 is a dedicated kit for R8i frame, ACS800 drives with other frame sizes may have different AGPS kit part numbers
If drive already has +Q950 function but AGPS board is damaged, recommend first confirming failure cause, if necessary have professional engineer inspect before deciding to replace board or entire kit
After retrofit kit installation, must perform safety function verification to ensure function is correctly implemented
