5-31.8 SAK 0.0 WFF 163 6.0-30. 1.5 2.5 1. acid- and alkalifree Vaseline, and connect the terminal immediately.0 SAK-Series SAK 2. Solid round and sector conductors Terminal type Rated cross-section Reduced rated current when connecting an aluminium conductor Clamping screw thread size Tightening torque W-Series mm2 „A“ Nm WDU 2.5 0. with a knife, remove the layer oxide. Caution: not use brushes, files or emery paper because particles of aluminium can deposited on other conductors.0-12.0 WDU 4. 4. Fit the washer in such way that the copper side in contact with the current bar, and the aluminium side contact with the cable lug. Repeat the above procedure any time the conductor disconnected and reconnected.0-6. Installation advice when using flat cable lugs When tightening the terminal is advisable hold the conductor to prevent deformation the terminal rail and avoid twisting the foot the terminal.6 SAK 2. 3.5 0.8 WDU 1.0 WFF 120 120 230 10.0-6. 2.5 WDU 3.0 WFF 300 300 409 30. After removing the layer oxide, coat the end the conductor immediately with neutral grease, e. Fixing screw Current bar 1 3 2 4 5Al side Al conductor Cu-plated washer 1 2 3 It necessary fit copper-plated aluminium washer between the aluminium cable lug and the copper current bar the modular terminal.4 SAK 105 4.0-2. This the only way guaranteeing a reliable transition between the copper and the aluminium.0 WDU 240 240 415 25. When connecting stranded aluminium conductors modular terminals, advisable use an aluminium cable lug chosen match the type conductor and connected according the instructions the cable lug manufacturer.0-2.0 SAK 3. And that, in unfavourable conditions, can lead to poor contact.0 Stranded conductors W-Series WFF 105 3.5 0.2 WDU 3.251282250000 2012/2013 . In contrast copper, aluminium exhibits certain characteristics that must taken into account when using this material conductor in electrical engineering.5 2.5 2. A thin, non-conductive layer oxide forms immediately the unprotected surface the aluminium soon it is exposed the air.0 Al cable lug Cu side 4 5 W Technicalappendix W.4 SAK 2. This layer increases the contact resistance between the aluminium conductor and the current bar of the modular terminal.5-0.g. Scrape the stripped end the conductor carefully, eg.0 WFF 185 185 300 15.2-1.5 2.4 WDU 0.Installation instructions The use aluminium conductors Weidmüller terminal blocks are suitable for the direct connection single strand round and sector-shaped aluminium wires.6-1.0-20. The above installation instructions are valid for solid round sector aluminium conductors only.0-60.0 WDU 120 150 290 15
