Up !CAUTION Do not touch the terminal section (charged parts) when power is being supplied. Always use the Relay with terminal covers mounted. Contact with charged parts may result in electric shock. Do not touch the Relay when power is being supplied or right after the power has been turned OFF. The hot surface may cause burn injury. DIN Track (35 mm) • Provide at least 5 mm of space between the sides and top of the Relay and nearby grounded metal surfaces. 5 mm min. ■ Precautions for Correct Use Installation • Mount the G7Z with the coil terminal at the top. Up Grounded metal surface 5 mm min. Coil terminal 5 mm min. • Provide at least 30 mm of space between Relays when two or more Relays are mounted in a row. 30 mm min. • Do not use the Relay with the terminal screw surfaces facing down. • The auxiliary contact block (G73Z) can be mounted on the Relay. Mounting and Removal Mounting Insert the tab on the auxiliary contact block into the groove on the Relay and press down until the hook on the auxiliary contact block catches in the mounting hole on the Relay. Hook (1) Tab (2) Terminal screw surface • To mount the Relay, secure M4 screws in two locations. Use a screw-tightening torque of 1.2 to 1.3 N•m. 39 mm Removing Slide the auxiliary contact block, remove the auxiliary contact block tab from the groove on the Relay, and remove the auxiliary contact block hook from the Relay. Be careful not to apply excessive force on the hook. Washer (external dia.: 7 max.) (1) Tab (2) Hook • The Relay can be mounted directly on a mounting rail (PTP) or a DIN Track (EN 50022-35 x 7.5, 15). The Relay cannot be mounted, however, to some reinforced rails (e.g., those produced by Kameda Denki or Toyogiken). Power Relays G7Z 335 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. Relay Coil 6.8 4.3 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. 336 Power Relays G7Z Omron Electronic Components, LLC Terms and Conditions of Sales I.
