It is connected to a blind switch with interlock. Then you set the end positions \u2013 mechanically on the motor head or electronically using the hand-held transmitter. The connection to the mains is done by a qualified electrician.<\/p>\n<h2>Safety first<\/h2>\n<p>Work on the 230 V mains may only be carried out by a qualified electrician. Before any work: switch off the circuit breaker, secure it against being switched on again and verify that the circuit is dead with a voltage tester. Secure the shutter beforehand so the curtain cannot unroll during removal.<\/p>\n<h2>The four wires: tubular motor wiring<\/h2>\n<table>\n<thead>\n<tr>\n<th>Wire<\/th>\n<th>Function<\/th>\n<th>Connection<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Blue<\/td>\n<td>Neutral (N)<\/td>\n<td>N at the switch or in the junction box<\/td>\n<\/tr>\n<tr>\n<td>Brown<\/td>\n<td>Phase, direction 1<\/td>\n<td>Switch output \u201cup\u201d or \u201cdown\u201d<\/td>\n<\/tr>\n<tr>\n<td>Black<\/td>\n<td>Phase, direction 2<\/td>\n<td>second switch output<\/td>\n<\/tr>\n<tr>\n<td>Green-yellow<\/td>\n<td>Protective earth (PE)<\/td>\n<td>PE<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>This applies to most 230 V tubular motors with wired control. The motor\u2019s data sheet is always decisive \u2013 for A-OK motors you will find it under Downloads on the respective product page. If the shutter runs the wrong way, swap brown and black at the switch.<\/p>\n<h2>Which switch is suitable?<\/h2>\n<ul>\n<li><strong>Blind switch or push-button with interlock:<\/strong> Up and down must never be energised at the same time. Normal double switches are not suitable.<\/li>\n<li><strong>Several motors on one switch:<\/strong> Do not simply connect motors with mechanical end positions in parallel. Use isolating relays or a group control instead.<\/li>\n<li><strong>Radio motors:<\/strong> only need a permanent supply (phase, neutral, earth). They are operated by hand-held or wall transmitter, no blind switch is needed.<\/li>\n<\/ul>\n<h2>Setting the end positions<\/h2>\n<h3>Mechanical end positions (e.g. A-OK AM45 mechanical)<\/h3>\n<ol>\n<li>Run the shutter down with the switch until the motor stops by itself.<\/li>\n<li>There are two adjusting screws on the motor head, marked with arrows for the directions of rotation.<\/li>\n<li>Turn the screw for the relevant direction \u2013 usually marked plus and minus: towards plus the shutter travels further, towards minus it stops earlier.<\/li>\n<li>Briefly run up and down again, check and readjust. Repeat for the upper end position.<\/li>\n<\/ol>\n<p>Set the upper end position so that the curtain does not pull against the stop in the box.<\/p>\n<h3>Electronic end positions (e.g. A-OK AM45 radio, AM55)<\/h3>\n<p>Electronic end positions are programmed with the hand-held transmitter or a setting cable \u2013 the sequence of button presses is given in the motor\u2019s instructions. The A-OK AM45 radio tubular motor can learn the end positions automatically, semi-automatically or manually and recalibrates them every 100 cycles.<\/p>\n<h2>A-OK motors at a glance<\/h2>\n<table>\n<thead>\n<tr>\n<th>Motor<\/th>\n<th>Torque<\/th>\n<th>End positions \/ control<\/th>\n<th>Suitable for<\/th>\n<th>Net price<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td><a href=\"https:\/\/ventsystems.de\/en\/product\/a-ok-am35-tubular-motor\/\">A-OK AM35 tubular motor<\/a><\/td>\n<td>6 \/ 10 Nm<\/td>\n<td>mechanical or electronic with radio<\/td>\n<td>small shutters, 40 mm octagonal shaft<\/td>\n<td>from \u20ac69<\/td>\n<\/tr>\n<tr>\n<td><a href=\"https:\/\/ventsystems.de\/en\/product\/a-ok-am45-tubular-motor-mechanical\/\">A-OK AM45 mechanical tubular motor<\/a><\/td>\n<td>15\u201350 Nm<\/td>\n<td>mechanical, wall switch<\/td>\n<td>roller shutters, roller doors, awnings, 60 mm octagonal shaft<\/td>\n<td>from 65 \u20ac<\/td>\n<\/tr>\n<tr>\n<td><a href=\"https:\/\/ventsystems.de\/en\/product\/a-ok-am45-radio-tubular-motor\/\">A-OK AM45 radio tubular motor<\/a><\/td>\n<td>6\u201330 Nm<\/td>\n<td>electronic, radio 868 MHz, obstacle detection<\/td>\n<td>roller shutters with convenient operation<\/td>\n<td>from \u20ac100<\/td>\n<\/tr>\n<tr>\n<td><a href=\"https:\/\/ventsystems.de\/en\/product\/a-ok-am45e-awning-motor\/\">A-OK AM45E awning motor<\/a><\/td>\n<td>30\u201350 Nm<\/td>\n<td>with emergency hand crank<\/td>\n<td>Awnings<\/td>\n<td>from \u20ac125<\/td>\n<\/tr>\n<tr>\n<td><a href=\"https:\/\/ventsystems.de\/en\/product\/a-ok-am55-venetian-blind-motor\/\">A-OK AM55 external venetian blind motor<\/a><\/td>\n<td>6\u201320 Nm<\/td>\n<td>electronic, wired or radio<\/td>\n<td>Raffstores and external venetian blinds<\/td>\n<td>from \u20ac97<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>Which torque your shutter needs and which shaft fits is explained in the guide <a href=\"https:\/\/ventsystems.de\/en\/roller-shutter-motor\/\">Retrofitting &amp; replacing a roller shutter motor<\/a>.

The connection to the 230 V mains must be carried out by a qualified electrician.<\/p>\n<h3>Which wire is up and which is down?<\/h3>\n<p>That depends on the mounting side: a motor installed on the left turns the other way than one installed on the right. So connect brown and black on a trial basis first and swap them if the direction is wrong.<\/p>\n<h3>Can I connect two roller shutter motors to one switch?<\/h3>\n<p>Not directly in parallel if the motors have mechanical end positions. Use an isolating relay or a group control so that the motors do not interfere with each other.<\/p>\n<h3>Do I need a switch for a radio motor?<\/h3>\n<p>No. A radio motor only needs a permanent power supply. It is operated via hand-held transmitter, wall transmitter or timer.<\/p>\n<h2>Questions about your shutter?<\/h2>\n<p>Send us the shaft diameter, shutter size and material \u2013 we will name the right motor.
