Safety Precautions
Refer to the “Precautions for All Relays” and “Precautions for All Relays with Forcibly Guided Contacts”.
!WARNING
Take measures to prevent contact with charged parts
when using the Relay for high voltages.
!CAUTION
• The Relay can be mounted directly on a mounting rail (PFP) 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.
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

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

• 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
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.

Removing
Slide the auxiliary contact block, remove

groove on the Relay, and remove the
auxiliary contact block hook from the
Relay.
Be careful not to apply excessive force
on the hook.

• Use round or open-end (Y-type) crimp terminals and connect the
terminals with the appropriate tightening torque. Refer to the

dimensions.

• 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.
• 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.

• 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.
