2. Using others than reverse polarity protected connectors will void your warranty Suitable for up to 35A are Gold 2mm with limitations Gold 2 5mm or the green MPX 6 pin systems For higher currents 4mm systems like the Conzelmann CT4 may be used available as accessory Soldering instructions for 43 cables to 4mm CT4 connectors 43 battery Feed red cable from the rear through the tighter red tube of the double housing solder female socket and press it in 43 battery Feed black cable from the rear through the wider tube of the double housing solder male pin and press it in f43 motor Feed red cable from the rear through the wider yellow tube of a split double housing solder pin and press it in f43 motor Feed black cable through the wider yellow tube of a split double housing solder pin and press it in Please use red housings on cables of accumulator pack and yellow housings on cables of your motor For correct installation of connectors we recommend to use a parallel vice and a hammer Damage to the socket during installation can be avoided by leaving a single pin inserted The cut off tighter housing halves are used to insulate the sockets soldered to the motor cables If motors with integrated sockets are used the leftover housing halves are replaced by yellow heat shrink tubing Whenever possible the motor should be directly soldered to the motor cables red and yellow of the f43 Keep the length of
3. All 43 have been examined carefully before the delivery under practice conditions with accumulators at the motor If you should have reason for the complaint please send the device back tous with aclear error description The text No 100 function is not enough Test the f43 carefully once more before returning it If our tests show no problem with your device you have to buy the costs of our testing Itis insignificant whether the device will be send back within the time of warranty or later Hint If you have a problem with a device of us please send it directly back to us without previously soldering in it So the results of repair are the fastest the costs remain low and warranty errors are recognized without doubt Then you can be sure too that only original parts will be inserted We have had to make already bad experiences with alleged service stations Cause of previously done repair outside of our firm and or by improper repair the costs of repair can not longer be estimated a repair of such devices is possibly refused by us completely schulze elektronik gmbh prenzlauer weg 6 D 64331 weiterstadt tel 06150 1306 5 fax 1306 99 internet http www schulze elektronik com e mail mail schulze elektronik com schulze 43 speed controller series not recommended in addition with SIMPROP System 90 transmitters elektronik gmbh issue 9 2 97 page 4 of 4 user manual 10 Installation Instructions
