5.16 Bypass circuitPlease observe the following during bypass switching (controller shunt with mains voltage):• Mutual locking of mains contactor and bypass protection• Time delay of at least 1 second during switching• The controller “enable” (ON / OFF) must be simultaneously opened together with cut-off of theprotection on the controller output; during connection it must be simultaneously closed again.For this a programming is necessary ( IO Setup Enable ON / OFF).• By switching OFF necessary waiting period before renewed switching on amounts minimum 90seconds! ( connection suggestion for bypass with the required time-delay)• Never apply line voltage to the inverter output!5.17 Manual Bypass-Switch type S-D-25 and S-D-50As accessories are manual main switches with bypass function available.By switching OFF Frequency inverters necessary waiting period before renewed switching onamounts minimum 90 seconds!Switch position• |0| = Switch OFF supply line (lockable)• |AUTO| = Operation Control• |100 %| = Operation Bypass (controller without supply)Technical data• Line voltage max. 690 V, 50/60 Hz• Rated current– Type S-D-25 Part.-No. 349035: 25 A– Type S-D-50 Part.-No. 349040: 50 A• Dimensions w x h x d [mm]– Type S-D-25: 115 x 115 x 163– Type S-D-50: 135 x 135 x 188• Protection class IP65S-D-25AUTO0100 %3 ~ 400 VControllerS-D-2504.12.2007v_sd25.vsdManual Bypass-Switch type S-D-25 / S-D-505.18 Auxiliary contact for version with main switch "Q"For versions with built in main switch (type series FXDM..A Q the switch position is indicated by anauxiliary contact.Switch position |0| = |OFF|• Device switched off• Auxiliary contact open = terminals 33 - 34 interruptedNL1 L2 L3343301Switch position |1| = |ON|• Device switched on• Auxiliary contact closed = terminals 33 - 34 bridgedOperating Instructions Icontrol – model series FXDM Electrical installationL-BAL-E036-GB 1422 Index 008 Part.-No. 00154773-GB17/96
