Manually entering or leaving bypass mode
When the AC input power is normal, it is handled by the UPS in one of two ways:
•
The input AC power is sent to the inverter, where it is regulated and passed on to the load. This
is called normal mode or inverter mode.
•
The input AC power bypasses the inverter entirely and goes directly to the load with no
regulation. This is called
Bypass Mode
.
Usually only a technician will need to manually switch the UPS to Bypass mode.
T
HERE ARE TWO WAYS TO MANUALLY ENTER OR LEAVE BYPASS MODE
:
•
Using the manual bypass switch on the UPS rear panel.
•
Using the system console.
10.1.1
Entering bypass mode via the manual bypass switch
Note: the Manual Bypass Switch is OPTIONAL EQUIPMENT, not standard. If the customer desires a
Manual Bypass Switch it must be specifically ordered as a separate item.
The manual bypass switch on the Power+ rear panel can be used to move the system to bypass mode.
Simply turn the switch from the “UPS” position to the “BYPASS” position. The “Bypass” LED on the system
console lights.
Figure 7: The manual bypass switch on the rear panel
To end bypass mode and transfer the load back to the system inverter, simply turn the manual bypass
switch from the “BYPASS” position to the “UPS” position.
