Precautions for Correct Use

Installation

• Mount the G7Z with the coil terminal at the top. 

• Do not use the Relay with the terminal screw surfaces facing down. 

• To mount the Relay, secure M4 screws in two locations. 

Use a screw-tightening torque of 1.2 to 1.3 N·m. 

• The Relay can be mounted directly on a mounting rail (PTP) or a 

DIN Track (EN 50022-35 

×

 7.5, 15). 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. 

• Provide at least 5 mm of space between the sides and top of the 

Relay and nearby grounded metal surfaces.  

• Provide at least 30 mm of space between Relays when two or more 

Relays are mounted in a row. 

• 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. 

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. 

Take measures to prevent contact with charged parts 
when using the Relay for high voltages. 

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.
