A higher level of ingress protection rating willbe necessary if the working atmosphere is or can be corrosive or if the enclosure issubject to wet or dusty environments.4 3 DIN-rail MountingThe carrier is designed for mounting on 35mm x 7.5mm T-section “top hat” DIN rail toEN50022 and uses six built-in DIN clamp tabs to hold it on the rail. The F801 powermodules must be removed from the carrier to obtain access to the DIN-rail clampscrews.4 3 1 Mounting ProcedureBefore starting to mount the carrier on the DIN rail, rotate all six of the DIN clampscrews counterclockwise (i.e. unscrew) until the clamping tabs reach the positionshown in Figure 3a and none of the tabs extend into the channel for the DIN rail.a)b)Figure 3 - DIN rail clamp positions before mountingPress the carrier onto the DIN-rail and rotate each of the DIN clamp screws clockwiseuntil the tab tightens against the DIN-rail. The clamping tabs can be seen through theInspect clamps holes when they are in the correct position.4 4 Removal from DIN-railThe Power Modules must be removed from the carrier to obtain access to the DIN-rail clamp screws. Support the carrier by pressing it to the DIN-rail and unscrew(counterclockwise) the six DIN-rail clamp screws. Turn each screw approximately twofull turns when releasing its clamping tab from the rail. Remove carrier.
