Infinty epsilon loudspeaker phase adjustment on servo control


On the back of servo control of  infinty epsilon loudspeaker there is a switch to be adjusted to either  0 or  180 for phase change . This is to be adjusted with amplifier and loudspeaker . If this key is set on the wrong phase a very damaging signal runs through the amp and might  damages both amp and loudspeaker . It is not clear how this can be avoided from amp to amp and it is by simply by luck to have the correct phase. Any suggestion how this can be avoided prior to start of woofer amp ? The wrong set up could seriously damage both amp and loudspeaker !
Thanks

Thank you all . I do have all the instruction manuals (I/M) for Infinity Epsilon . In the I/M it only warns you if polarity on the servo is not set correctly and not compatible it severely damages amp and speakers . You only have a 50/50 chance when you try  the amp  which controls the woofer section of the speaker  . I can only tell that setting wrong polarity on the servo  is a dreadful experience and system could be severely damaged !
