2.40Reserve Power/Power Failure Options

2.41The STRATA DK systems offer two options to protect system operation in the event of a power failure; the Reserve Power option (Paragraph 2.42- 2.44), and the Power Failure Emergency Transfer option (Paragraph 17).

2.42Reserve Power Option STRATA DK16 sys- tem power supply provides the capability of con- necting a reserve power source (two customer supplied 12-volt batteries) to ensure uninterrupted system operation in the event of a power failure. A pre-assembled interface cable for installation of the Reserve Power option is available from Toshiba (PBTC-3M), refer to Figure 5-9.

IMPORTANT NOTE!

Local ordinances may dictate battery type and installation details.

2.43The batteries require a well-ventilated loca- tion close (within 9 feet) to the system —the interface cable is 9 feet long.

WARNING!

To reduce the risk of fire or injury to persons, read and follow these instruc- tions:

1.Use only the following type and size batteries: 12-volt, gelcell.

2.Do not dispose of the batteries in a fire. The cells may explode. Check with local codes for possible special dis- posal instructions.

3.Do not open or mutilate the batteries. Released electrolyte is corrosive and may cause damage to the eyes or skin. It may be toxic if swallowed.

4.Exercise care in handling batteries in order not to short the battery with con- duction materials such as rings, brace- lets, and keys. The battery or conduc- tor may overheat and cause burns.

5.Charge the batteries provided with or identified for use with this product only in accordance with the instruc- tions and limitations specified in this manual.

6.Observe proper polarity orientation between the batteries and battery charger.

2.44Reserve Power Installation. Install the Re- serve Power option in accordance with the follow- ing steps (refer to Figure 5-9):

1)Connect the PBTC-3Mblack jumper wire from the positive terminal of one 12VDC battery to the negative terminal of the second 12VDC battery.

2)Ensure that a serviceable 10-ampere fuse is installed in the in-line fuse holder of the PBTC- 3M battery cable.

3)Connect the white lead of the PBTC-3Mbat- tery cable to the open positive terminal of the 12VDC battery. Connect the black lead to the open negative terminal of the second 12VDC battery.

IMPORTANT NOTE!

The KSU must be connected to the live operating (HOT) AC power source, and the power supply ON/OFF switch set to ON prior to the final step of connecting the reserve power batteries to the power sup- ply via the BATT +/- receptacle. If the batteries are connected after AC power is lost, reserve power will not function.

4)Connect the PBTC-3Mbattery cable two- prong male plug to the power supply BATT +/ - receptacle.

5)To test reserve power operation, disconnect the system AC power plug with the power supply power ON/OFF switch in the ON posi- tion. The system should continue to operate without any interruption.
