Certified Standards Forcibly Guided Contacts (from EN50205) G7SA * EN Standards, VDE Certified EN61810-1 (Electromechanical non-specified time all-or-nothing relays) EN50205 (Relays with forcibly guided (linked) contacts) * UL standard UL508 Industrial Control Devices * CSA standard CSA C22.2 No. 14 Industrial Control Devices If an NO contact becomes welded, all NC contacts will maintain a minimum distance of 0.5 mm when the coil is not energized. Likewise if an NC contact becomes welded, all NO contacts will maintain a minimum distance of 0.5 mm when the coil is energized. 5 G7SA Safety Precautions Refer to the "Precautions for All Relays" and "Precautions for All Relays with Forcibly Guided Contacts". Precautions for Correct Use Wiring * Use one of the following wires to connect to the P7SA-10F/10F-ND/14F/14F-ND. Stranded wire: 0.75 to 1.5 mm2 Solid wire: 1.0 to 1.5 mm2 * Tighten each screw of the P7SA-10F/10F-ND/14F/14F-ND to a torque of 0.78 to 0.98 N*m. * Wire the terminals correctly with no mistakes in coil polarity, otherwise the G7SA will not operate. Cleaning The G7SA is not of enclosed construction. Therefore, do not wash the G7SA with water or detergent. 6 Read and Understand This Catalog Please read and understand this catalog before purchasing the products.
