Chapter 12 : Maintenance - Delta Amplon RT Series User Manual

1. Unscrew the screws shown in Figure 27 to remove the cover plate of the
MANUAL BYPASS SWITCH.
NOTE :
Under the cover plate, there is a manual bypass detector (please
see Figure 28). Once the cover plate is removed, the detector will
automatically activate to send a message to the UPS. The message is to
ask the UPS to transfer into bypass mode. If there is a power interruption
while the UPS is running in bypass mode, the connected loads won't be
protected.
2. After you confirm that the UPS has been run in bypass mode, switch the
MANUAL BYPASS SWITCH to the BYPASS position (please see Figure 29).
