The Relay cannot be mounted, however, to some reinforced rails (e.g., those produced by Kameda Denki or Toyogiken). • Mount the Relay sideways when it is mounted on a rail. • Use End Plates (PFP-M) on both sides of the Relay to make sure that it is properly secured. Up 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. Precautions for Correct Use Installation DIN Track (35 mm) • Provide at least 5 mm of space between the sides and top of the Relay and nearby grounded metal surfaces. • Mount the G7Z with the coil terminal at the top. 5 mm min. Grounded metal surface Up Coil terminal 5 mm min. 5 mm min. • Provide at least 30 mm of space between Relays when two or more Relays are mounted in a row. • Do not use the Relay with the terminal screw surfaces facing down. 30 mm min. • The auxiliary contact block (G73Z) can be mounted on the Relay. Mounting and Removal Mounting 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. 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. (1) Hook Tab (2) 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. (1) Tab (2) Hook 6 G7Z Connecting Coil • 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. Relay Contacts (Unit: mm) (Internal Connections of Coils) DC Coil A2 • If a transistor drives the G7Z, check the leakage current and connect a bleeder resistor if necessary. 14.5 12.5 11 6 6 • 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. • Counter-electromotive voltage generated by the coil when the coil is OFF may destroy semiconductor elements or cause malfunctions. Attach surge-absorbing diodes to both ends of the coil as a countermeasure. Particularly, when driving G7Z with semiconductor elements, always attach the surge-absorbing diodes. Note that the relay reset time will be extended, so always use after verifying implementation under actual usage conditions. Use surge-absorbing diodes with a minimum of 600 V reverse voltage resistance, and a forward current of approximately 1A. G7Z does not have coil polarity so attach surge-absorbing diodes so that the polarity is reverse to the applied voltage of the coil. M5 Relay Coil 6.8 4.3 M3.5 Auxiliary Contact Block 9.5 6.8 Mirror Contact Mechanism 5.5 5.5 M3.5 • One crimp terminal can be used for the Relay contact section (M5 screw). Two crimp terminals can be connected for the coil terminal and auxiliary contact block. By combining a Relay with an auxiliary contact block, all NC contacts of the auxiliary contact block will satisfy an impulse withstand voltage of 2.5 kV or higher or maintain a gap of 0.5 mm or greater when the coil is de-energized even if at least one NO contact (main contact) of the Relay is welded. Description of Mirror Contact Mechanism Recommended Crimp Terminals and Wire Location Contact section Coil section Crimp terminals A1 Impulse withstand voltage: 2.5 kV min. or contact separation (a + b): 0.5 mm min.

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. Relay NC NO NC NO NO NO Contact welding 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. 7 Read and Understand This Catalog Please read and understand this catalog before purchasing the products.
