G7SA G7SA Precautions Safety Relays Cleaning A Safety Relay is a Relay with which a safety circuit can be configured. The G7SA is not of enclosed construction. Therefore, do not wash the G7SA with water or detergent. Wiring Forcibly Guided Contacts (from EN50205) Use one of the following wires to connect to the P7SA-10F/10FND/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 0.98 N S m securely. Wire the terminals correctly with no mistakes in coil polarity, otherwise the G7SA will not operate. 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. ALL DIMENSIONS SHOWN ARE IN MILLIMETERS.
