Item Descript ion (Location) Function
1 Display Screen
(SCC and modules)
This screen displays all vital UPS information in one convenient location. All of the UPS
monitoring functions and conditions are indicated here.
2 Up
(SCC and modules)
This touch-sensitive pad (button) is used to move the c ursor up through various
selections present on the display screen. Note that all pads on this control panel have
touch-sensitive switches behind them.
3 Down
(SCC and modules)
Similar to the Up pad, this pad is used to move the cursor down through the various
selections present on the display screen.
4 Select
(SCC and modules)
After choosing the desired item (with highlighted cursor) from the display screen with
the Up and Down pads, pushing this pad tells the microprocessor to go to the
highlighted selection.
5 Alarm Reset
(SCC and modules)
This pad is used to clear all of the alarm conditions that are no longer present.
However, all active alarms remain in memory and on the applicable screens until they
are corrected. This pad also resets the History Status Report memory buffer when held
until the screen clears.
6 Voltage Adjust
(SCC only)
This push-to-turn knob permits adjustment of the UPS output voltage to meet load
requirements or to match the bypass voltage before transferring the load to or from
bypass.
7 UPS
(SCC only)
This pad activates the circuits that connect the UPS to the critical load (a retransfer).
When this pad is pushed (along with Control Enable), the UPS output circuit breaker
closes and the bypass circuit breaker opens.
8 Bypass
(SCC only)
This pad activates the circuits that connect the bypass line to the critical load (a
transfer). When this button is pushed (along with Control Enable), the bypass circuit
breaker closes and the UPS output circuit breaker opens.
9 Control Enable
(SCC and modules)
This pad must be pressed simultaneously with the UPS, Bypass, Battery Trip, or Output
Trip pads to activate them.
10 Horn Off
(SCC only)
This pad is used to silence the alarm horn after it is activated. When this switch is

During an emergency, pressing this guarded switch will transfer the load to bypass and
then shut down the UPS modules. The load will remain on bypass power. (Refer to
3.3.3 - Shutdown Procedures.)
13 Battery Trip
(modules only)
This pad can be used (along with Control Enable) to trip the module battery disconnect
(MBD) circuit breaker open (disconnecting the battery from the UPS module).
