Power Relays G7Z 9 Connecting · Use round or open-end (Y-type) crimp terminals and connect the terminals with the appropriate tightening torque. Refer to the terminal section space in the following figure for the crimp terminal dimensions. Operating Coil (Internal Connections of Coils) DC Coil A2 A1 Relay Contacts (Unit: mm) 14. 5 12. 5 11 6 6 M5 · If a transistor drives the G7Z, check the leakage current and connect a bleeder resistor if necessary. · The must operate voltage is the minimum value for the Relay armature to operate and the contacts to turn ON. Therefore, fundamentally apply the rated voltage to the coils, taking into consideration the increases in coil resistance caused by voltage fluctuation and coil temperature rise. Mirror Contact Mechanism By combining a Relay with an auxiliary contact block, all NC contacts of the auxiliary contact block will satisfy an impulse withstand voltage of more than 2. 5 kV or maintain a gap of more than 0. 5 mm when the coil is de-energized even if at least one NO contact (main contact) of the Relay is welded (according to EN 60947-4-1).

Loose screws may result in fire caused by abnormal heat generated when the power is being supplied. M5 screws: 2. 0 to 2. 2 N·m M3. 5 screws: 0. 8 to 0. 9 N·m · Allow suitable slack on leads when wiring, and do not subject the terminals to excessive force. Microloads The G7Z is used for switching power loads, such as current carry for device power supplies and heater loads. Use an auxiliary contact block (G73Z) if microloads are required for signal applications and operation status feedback. 10 Power Relays G7Z Power Relays G7Z 11 Warranty and Application Considerations Read and Understand this Catalog Please read and understand this catalog before purchasing the products.
