Opening the Main Cabinet Door
- Before opening the main cabinet door, turn off all upstream switches for the SACU to power off the SACU. After that, wait at least three minutes and then operate the SACU. If you have to operate the SACU with power-on, wear insulation gloves and take protective measures.
- If you need to open the main cabinet door on rainy or snowy days, take protective measures to prevent rain or snow from entering the cabinet. If it is impossible to take protective measures, do not open the main cabinet door on rainy or snowy days.
- Do not leave unused screws in the cabinet.
Loosen the screws on the main cabinet door, open the cabinet door, and adjust the support bar.
