Attach the spade fork connectors to the terminals on the control unit (see wiring diagram Fig. 7) and fix them
tightly by the screws. A safe and good quality connection on each cable is again essential.
Find a suitable place for the battery power isolation switch (23) which includes an external holder with hinged
cover. Important: The switch must be mounted onto the exterior body of the caravan and be easily
accessible from the outside of the caravan in case of any emergency. The switch must be mounted close
to the location of the battery in order to keep the length of the battery cables to a minimum.
Use the cardboard template to position the hole positions and the drill holes. Mount the switch and the housing
with the bolts, washers and nuts, and finally mount it on the caravan with stainless steel screws (12).
Route the positive (+) power cable (including fuse) from the battery to the battery power isolation switch and
then further to the control unit.
Cut the positive power cable to an appropriate length and remove approx. 5mm of the insulation from the ends.
Fix the O-ring connectors (21) by using crimping pliers. A secure and good quality connection on each cable is
essential.
The electronic connections of the battery power isolation switch must be covered by the supplied rubber
isolation shells (24).
Route the negative (-) power cable directly from the battery to the control unit.
No cables may be routed over the control unit!
Again it is recommended to use the supplied trunking (25) to protect the cables against sharp edges. Attach the
cables and trunking with the cable ties (16) or P-clips (13 & 14) and P-clip screws (12).
Cut the cables to an appropriate length and remove approx. 5mm of the insulation from the ends. Fix the spade
connectors (22) by using crimping pliers. A secure and good quality connection on each cable is essential.
Connect the battery cables (18 & 19) to the control unit: Attach the spade fork connectors to the positive (+)
en negative (-) terminal of the control unit and fix them tightly by the screws.
Connect the battery cables to the existing battery terminals (red = positive, black = negative). Two types of
battery terminal connector (20 & 21) are provided for use as appropriate.
Caution! Make sure that you do not reverse the positive (+) and negative (-) connections.
Incorrect connection (reverse polarity) will result in damage to the control unit.
Seal 25mm hole in vehicle under body using plastic body sealant.
Next you can connect the cable for the emergency draw back function (option, not obliged). If you forget to
draw back the corner steady before you start to drive, the corner steady or your caravan can get significant
damage. This emergency draw back function ensures that (if installed properly!) the corner steady will be
drawn back automatically when the caravan is connected on the constant 12 Volt power source of the car (via 7
or 13 pin plug).
Connect one end of the blue cable for the emergency draw back function (17) to the constant power source
(+12V) of the car (via 7 or 13 pin connector) and not in direct connection is with the caravan battery! You can
also find this constant power source in the 12 Volt central distribution box of your caravan. It is normally used
to use your refrigerator during driving. If necessary measure again with a multimeter.
If necessary you also need to connect the ground (-) of the car power source to the minus (marked 12V-) of
the control unit (when the caravan battery is also used for lighting/water pump of the caravan this is not
necessary).
If you need any help finding the constant power source of the car (in your caravan) please contact the
manufacturer or supplier of your caravan for the wiring diagram.
NOTE: This constant e cable power source (+12V) CANNOT be in direct connection with the
caravan battery! Check this very carefully, otherwise the autoSteady system will not work!
You can test this by disconnecting the connector from the car so the constant +12V voltage
drops. By connecting the connector on the car again, the +12V voltage will be restored. If
you have doubts you can drop this option (it is not obliged).
Route the cable for the emergency draw back function from the constant power source (+12V) to control unit.
Again it is recommended to use the supplied trunking (25) to protect the cables against sharp edges. Attach the
cable and trunking with the cable ties (16) or P-Clips (13 & 14) and mounting screws for P-Clip (12).
Cut the cables to the correct length. Remove approx 5mm of the insulation from the end. Fix the spade
connectors (22) by using crimping pliers. A secure and good quality connection on each cable is essential.
