136 ~~**G7SA**~~ ~~**G7SA**~~ ## ~~Precautions~~ ## **Safety Relays** A Safety Relay is a Relay with which a safety circuit can be configured. ## **Wiring** Use one of the following wires to connect to the P7SA-10F/10FND/14F/14F-ND. Stranded wire: 0.75 to 1.5 mm[2] Solid wire: 1.0 to 1.5 mm[2] ## **Cleaning** The G7SA is not of enclosed construction. Therefore, do not wash the G7SA with water or detergent. ## **Forcibly Guided Contacts (from EN50205)** 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. Tighten each screw of the P7SA-10F/10F-ND/14F/14F-ND to a torque of 0.98 N � m securely. Wire the terminals correctly with no mistakes in coil polarity, otherwise the G7SA will not operate. ## **ALL DIMENSIONS SHOWN ARE IN MILLIMETERS.** To convert millimeters into inches, multiply by 0.03937. To convert grams into ounces, multiply by 0.03527. Cat.
