g7s 7 precautions j forcibly guided contacts when no contacts are welded, the coil will be non-energized so all nc contacts will maintain a distance between the contacts of 0.5 mm minimum. likewise if nc contacts are welded, the coil will be energized so all contacts will maintain a distance between each other of 0.5 mm minimum. caution do not touch the terminal area of the relays or the socket ter- minal area (charged area) while power is on. electric shock will result. j safety relays a safety relay is a relay with which a safety circuit can be configured. for common precautions when using and handling relays, consult omron. j contacts the coil terminals have polarity ( positive and negative).operation is not possible if these are connected in reverse. ! omron on-line global - http://www.omron.com usa - http://www.omron.com/oei canada - http://www.omron.ca all dimensions shown are in millimeters. to co nvert millimeters into inches, divide by 25.4 cat. no. gc safety-2 a printed in usa omron canada, inc. 885 milner avenue toronto, ontario m1b 5v8 416-286-6465 omron electronics llc one commerce drive schaumburg, il 60173 847-843-7900 for us technical support or other inquiries: 800-556-6766 2/03 -11/06 specifications subject to change without notice
