• If any battery emission contacts the skin, wash immediately and thoroughly with water .

Follow your company’s approved chemical exposure procedures.

• If any battery emission contacts the eye, wash immediately and thoroughly with water for

10 minutes with pure water or a special neutralizing eye wash solution and seek
immediate medical attention. Follow your company’s approved chemical exposure
procedures.

• Neutralize any spilled battery emission with the special solution contained in an approved

spill kit or with a solution of 1 lb. bicarbonate of soda to 1 gal of water. Report chemical
spill using your company’s spill reporting structure and seek medical attention if
necessary.

• Always replace batteries with those of an identical type and rating. Never install old or

untested batteries.

• Do not charge batteries in a sealed container . Each individual battery should have at least

0.5 inches of space between it and all surrounding surfaces to allow for convection cooling.

• All battery compartments must have adequate ventilation to prevent an accumulation of

potentially dangerous gas.

3.1 Important Troubleshooting Notes

Always troubleshoot communication problems before working on battery-related and/or generator­related problems. The embedded transponder runs off of the power supply’s USM2.5 logic voltages,
and does not require the sensing cables (from the batteries or the generator) to communicate.

1.

USM2.5 Switch Set-up: The 8 position “DIP” switch on the USM2.5 board must be set correctly .
See the complete chart in the USM2.5 Status Monitor Operator’s and T echnical Manual P/N
704-683-B0-xxx. Note that SW1-4 (the fourth switch from the front) must be turned ON when
using an internal Acterna transponder .

2. Transponder Address: The transponder address is the five (5) digit number printed on the sticker
on the FRONT of the Embedded T ransponder Assembly , above the “F” connector . The address

is not the printed circuit board serial number (typically in the format of 1B followed by six
numbers) from the sticker on the PCB itself. The address can be verified from the SOC (Sys-

tems Operation Center).

3. Transponder Driver: The correct Acterna device driver must be downloaded from the HEC to the
transponder. The following is Acterna’ s list of device drivers for embedded (internal) transponders
in Alpha T echnologies XM2 power supplies, as of 17 October 2002.

3. 1 Impor tant Troubleshooting Notes,

If there are two power supplies in the same enclosure, make sure that the interface cable from
the generator ECM is connected to the correct embedded transponder.

4. Battery Voltage Jumper: Verify that the battery voltage jumper block is in the correct position:

continued

• The jumper will be installed in the bottom position for 36VDC battery systems (shorting the

bottom two rows of pins, and with the top row of pins exposed)

• The jumper will be installed in the top position for 48VDC battery systems (shorting the top

two rows of pins, and with the bottom row of pins exposed).
Use extreme care when removing the jumper – lift the jumper only , don’t pry the pin assembly
off the PC board.

5. Battery Voltage Sensing: Verify the battery sensing cables are connected correctly – battery
polarity is critical. The battery numbering / labeling conforms to the requirements of the SCTE
HMS standard. (Refer to section 1.3, Battery Monitor Connections.) The battery numbering
shown in Acterna’ s CheetahNet display will be as listed in the manual.

• Each string is labeled A, B, C, or D, shown as “x” below. Not all battery sensing wires will

be present in all harnesses. For example, in a 2 string system, there may only be one
NEG wire - connect to either string’s battery # 1 negative post.
