Do not touch its terminals while the power is turned on because the terminals are charged and may cause an electric shock. All G9S-series Relays fall under Safety Category 4 of EN954-1 except the G9S-321-T. The G9S-321-T has an OFF-delay output block falling under Safety Category 3. Use the following to wire the G9S. Strand wire: 0.75 to 1.5 mm2 16 to 18 AWG Steel wire: 1.0 to 1.5 mm2 16 to 18 AWG The above is provided according to circuit examples presented by OMRON. Therefore, the above may not apply to all operating environments. Tighten each screw to a torque of 0.78 to 1.18 NSm (8 to 12 kgfScm), or the G9S may malfunction or generate heat. The applicable safety category is determined from the whole safety control system. Make sure that the whole safety control system meets EN954-1 requirements. External inputs connected to T11 and T12 or T21 and T22 of the G9S-301 must be no-voltage contact inputs. Safety Category 4 of EN954-1 PE is a ground terminal. Apply 2-channel external input to the T11 and T12 terminals and T21 and T22 terminals through switches each incorporating a force-separation mechanism. If limit switches are used, make sure that at least one of them incorporates a force-separation mechanism. When a machine is grounded at the positive, the PE terminal should not be grounded. J MOUNTING MULTIPLE UNITS Refer to Application Examples and input a signal for the normally-closed contact of the contactor (i.e., input to X1 of the G9S-301, X2 of the G9S-501, or X2 of the G9S-321-T). If the output current is 3 A or more, make sure that there is a minimum distance of 50 mm (1.97 in) each between all adjacent G9S Units. (24-VDC models do not require this spacing.) Be sure to ground the PE terminal. If the relay is operating with DC, the power supply may be grounded instead. 50 mm min. (1.97) J FUSE REPLACEMENT Three- and Five-Pole Models The power input circuit of the G9S includes a fuse to protect the it from damage that may be caused by short-circuiting. The fuse is mounted to the side panel. Use the following type of fuse as a replacement. Littel Fuse 218.4 (rated current 0.4 A), IEC127 approval. Use a flat-blade screwdriver to remove the fuse cover. Be sure to turn off the G9S before replacing the fuse. Fuse 11 ALL DIMENSIONS SHOWN ARE IN MILLIMETERS.
