New Product

Uninterruptible Power Supply (UPS)

S8BA

Compact DC-DC UPS with a DIN rail for

mounting, best suited for prevention of

voltage drop and power failure in

industrial-purpose computers

(IPC)/controllers

• System reliability greatly improved because

24VDC power supply is backed up for a certain

period of time in the event of voltage drop or power failure.

• Compactness, weight reduction, and long battery life

realized thanks to the adoption of a lithium-ion battery.

• Push-in terminal block adopted for the power input and

output I/F.

• Shutdown in conjunction with the industrial

purpose computer (IPC) or controller realized

by the USB/RS-232C/I/O port installed in the UPS.

S8BA I/O signal functions Type of output signals Signal Description Backup signal output (BU) Stays ON during backup operation at a power failure. Low battery level signal output (BL) Goes ON when the battery becomes weak during backup operation at a power failure. Trouble signal output (TR) Goes ON when an internal failure of the UPS occurs or when the battery life counter expires.

S8BA Engineering Data Estimated backup time The backup time varies depending on the capacity of connected devices. After calculating the total capacity of connected devices, refer to the graph of the backup time to obtain an estimation of the initial value of the backup time. (This is also applied to checking the battery.) 1. Convert the total capacity (power consumption) of the connected devices to watts (W). For the indication of connected devices, check your computer and the rear of the display.

S8BA Safety Precautions Warning Indications Warning Indicates a potentially hazardous situation that, if not avoided, could result in serious injury or death. Additionally there may be significant property damage. Caution Indicates a potentially hazardous situation that, if not avoided, could result in minor or moderate injury or property damage. Meaning of Product Safety Symbols General inhibition Notice prohibiting an unspecified general action.

S8BA When you use plug strip and other plugs to connect additional devices, do not connect devices that exceed the current capacity of the available plugs. • The current protection of the unit may operate, which may stop the output. • The cable heats up, which may cause a fire. Do not pinch or sharply bend the cable. Do not fold or knot the cable. • Doing so may cause the cable to be damaged or heated, which may cause an electric shock or a fire.
PAGE 14
S8BA Do not throw the unit into fire. • Since the battery is incorporated in the unit, the insulator may melt, the gas exhaust valve or protection mechanism may be damaged, or the electrolyte may catch fire, and it may result eventually in an abnormal heating, smoke, rupture or fire. Do not insert metal objects into the input terminal block and the output terminal block of the UPS. • Doing so may result in electric shock. Do not insert metal objects into the battery connectors.
PAGE 15
S8BA Correct Installation Method • For installation, to improve the long time reliability of the UPS, pay much attention to heat dissipation. Ensure convection of air around the UPS main body, and use the UPS in an operating condition below the derating curve. • During machining work for mounting, make sure that no metal scrap goes into the product. • The heat dissipation of the UPS may become worse depending on how the UPS is mounted; in rare cases, internal components may deteriorate and get damaged.
PAGE 16
S8BA Precautions for Correct Use • For battery replacement, hold down the “Buzzer Pause/Test” switch on the unit for 10 seconds or longer to activate the battery replacement mode. When “ ” is displayed, the activation is completed. * Activate the battery replacement mode while the “input power supply” is turned ON. If you replace the battery without activating the battery replacement mode, the battery life may not be detected accurately because the battery life counter is not reset.

S8BA Conformance to FCC FCC CAUTION Changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment. • This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment.
