Battery Charging Procedure

3-6 Battery Charging Procedure

The battery power supply batteries can be recharged to a certain level without removing them from the battery power

supply case. Either a 115 Vac (105 to 1 25V) or + 28 V (22 to 30V) source can be used to recharge the batteries. The

battery supply can be either attached to or removed from the R/T unit while the batteries are charging. To recharge the

batteries, proceed as follows.

a. Connect the battery case power input terminal to a source of charging power as shown in Figure 3-2. Use

the cable supplied with the battery power supply for this purpose.

NOTE

The R/T unit will not operate properly when charging the supply from a 115 Vac

source. The R/T unit will operate properly when charging from a +28 V source.

b. Allow the battery supply to charge to the proper level. When using the 115 Vac source, the batteries will be

charged to 70 percent full charge in 40 hours. When using the 28 V source. the batteries will be charged to

80 percent full charge in 16 hours.
