PowerBox Systems PowerBox Cockpit SRS Instruction Manual page 5

3. First steps, the unit in use:
In the following instructions we do not differentiate between the
PowerBox Cockpit SRS and Competition SRS, since the method of
programming the two units is absolutely identical. The only difference is
that the PowerBox Cockpit SRS includes the door sequencer
function, whereas the PowerBox Competition SRS does not.
3.1. Connections
Plug the batteries into the MPX connectors on the backer with correct
polarity. We recommend PowerBox Batteries of 1500mAh,
2800mAh, 3200 mAh or 4000mAh capacity. If you prefer to use other
makes of battery, or packs you have assembled yourself, please take
particular care over polarity - it is always better to check twice rather
than make a mistake. If you connect a battery to the backer incorrectly,
this will immediately ruin the associated regulator. The unit does not
feature reverse polarity protection, as this minimises power losses
between battery and backer. The + markings are printed clearly on the
case cover.
Connect the SensorSwitch to the appropriate red socket. Note that the
ribbon cable must run upwards. In models subject to powerful vibration
we recommend that you secure the ribbon cable at a minimum of one
point in order to prevent the connector working loose and falling out.
Although this would have no effect on the switched state of the backer,
it would prevent you switching it off.
Do not connect the receiver yet! Please read Point 3.7. to establish
the essential initial settings.
3.2. The procedure for switching on and off
The method of switching the unit on and off is very simple, and the
process effectively eliminates the possibility of changing the backer's
status accidentally. This is the procedure
Locate the SET button on the SensorSwitch and hold it pressed in until
the central LED glows red. Now press buttons I and II in turn to switch
the backer on.
Repeat the procedure to switch off: hold the SET button pressed in, wait
until the central LED glows red, then confirm by pressing buttons I and
II in turn.
