DEATH ON CONTACTmay result if personnel fail to observe safety precautions. The power cable, interlockswitch, POWER switch, EMI filters, filter capacitor, and the power transformer withtheir associated wiring are components in the BATTERY charger which may have highvoltage on exposed terminals. Before working inside the equipment, set the POWER switch to OFF and remove the power cable from the power source. Ground highvoltage points before touching fumes or gases may be generated during BATTERY charging operations.

2 Besure the working area has adequate ventilation. Do not allow smoking or open flamenear charging batteries; vented gas may explode. Do not attempt to charge a damagedor leaking ventilation should be provided while using TRICHLOROTRIFLUOROE-THANE. Prolonged breathing of vapor should be avoided. The solvent should not beused near heat or open flame; the products of decomposition are toxic and TRICHLOROTRIFLUOROETHANE dissolves natural oils, prolonged contactwith skin should be avoided, When necessary, use gloves which the solvent cannotpenetrate. If the solvent is taken internally, consult a physician the BATTERY charger is to be prepared for shipment or placed in inactive storage formore than 30 days, remove the memory BATTERY (B1).SAFETY STEPS TO FOLLOW IF SOMEONEIS THE VICTIM OF ELECTRICAL SHOCKDO NOT TRY TO PULL OR GRAB THE INDIVIDUALIF POSSIBLE, TURN OFF THE ELECTRICAL POWERIF YOU CANNOT TURN OFF THE ELECTRICALPOWER, PULL, PUSH, OR LIFT THE PERSON TOSAFETY USING A WOODEN POLE OR A ROPE ORSOME OTHER INSULATING MATERIAL SEND FOR HELP AS SOON AS POSSIBLEAFTER THE INJURED PERSON IS FREE OFCONTACT WITH THE SOURCE OF ELECTRICALSHOCK, MOVE THE PERSON A SHORT DISTANCEAWAY AND IMMEDIATELY START ARTIFICIALRESUSCITATIONC hange 1 ATM 11-6130-392-12C1 ChangeNo.

DESCRIPTION AND DATA1-7. Purpose and UseThe PP-7286/U is a portable self-contained batterycharger designed to charge sealed ,nickel-cadmium(Ni-Cd) batteries such as: the BB-516/U used in theLaser Infrared Obscuration Set AN/GVS-5 herein-after referred to as LR; the BB-557( )/U (DigitalMessage Device AN/PSG-2); the BB-699( )/PAQ-l(Target Designator Laser); and the BB-704( )/U(GLLD).

9 It will charge any 6,12,24 or 28 voltsealed Ni-Cd BATTERY capable of either fitting in thefive BATTERY holders on the front panel (pressurecontacts adjustable from to inches) or beingattached to cables connected to the five sets of plug-in-connectors (jacks) located beneath the batteryholders. The MX-10154( )/U is used in conjunctionwith the PP-7286/U . The tray can accommodate upto six sealed nickel-cadmium (Ni-Cd) batteriesBB-503 DescriptionThe batter charger (figure 1-2) consists of an ac todc converter and five 15 to 700 mA constant currentcharging channels. The BATTERY charger operatesfrom either 115 vac or 230 vac, 47 to 400 Hz singlephase power channel is provided withan adjustable pressure contact BATTERY holder foraccepting sealed nickel-cadmium batteries, such asthe BB-516/U BATTERY , used in the LR.

10 Each chan-nel is also provided with remote BATTERY jacks foruse with external cables or clip leads. A CHANNELSELECT switch, VOLTAGE TEST SELECT switch,VOLTAGE TEST/CHG mA switch and a panelmeter are provided for setting individual channelcharge current and for monitoring individual bat-tery voltage. The individual channel currents areadjustable by means of FINE ADJ screws and aCURRENT SET locking toggle switch. The batterycharging tray is made of Lexan plastic material andfurnishes a means of charging one through sixBB-503/TAS batteries from a constant currentsource supplied by the charger . The tray is provi-ded with five single pole, single throw, normallyclosed, five ampere rating pushbutton switches andsix sockets. A cable assembly, terminated at oneend in a Y configuration, has a red banana plugat the positive terminal and a black banana plug atthe negative terminal.
