Built-in Power Supply
The built-in Power Supply in each BKSU and EKSU will convert 105V- 129V AC power to +5V DC 
voltage output. The power capacity of the Power Supply is as follows:
Battery Backup Unit Installation
The Battery Backup Unit (BBU) provides 
power for the system during a power failure. 
The BBU connects to the STS via the 
connector on the side of the BKSU.
Battery Backup Wiring
If local AC power fails, the system can be 
equipped to operate...

Power Line Surge Protection
The AC outlet should be equipped with a power surge protection device or UPS. Systems using 
such devices are more resistant to damage from power line surges than unprotected systems. 
Power line surges often occur during normal operations and during violent thunderstorms.
Installation of a surge protector meeting the specifications described in the following 
paragraph may prevent or minimize the damage resulting from power line...

PCB Handling and General Installation
The system cards contain digital circuitry which are extremely reliable, but can be damaged by 
exposure to excessive static electricity. When handling PCBs, a grounded wrist strap should be 
used to protect boards from static discharges. Also, use common sense when handling PCBs.
EXAMPLE -- Do not place a PCB in locations where heavy objects might fall on the PCB and 
damage components.
