Precautions
Be sure to read the common precautions provided in Best Control Devices Catalog Version 17 before using the Relay.
!WARNING
Take measures to prevent contact with charged parts
when using the Relay for high voltages.
!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.
Precautions for Correct Use
Installation
• Mount the G7Z with the coil terminal at the top.
Up
• Do not use the Relay with the terminal screw surfaces facing down.
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.
Washer (external dia.: 7 max.)
• 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.
Up
• Provide at least 5 mm of space between the sides and top of the
Relay and nearby grounded metal surfaces.
Grounded metal surface
• Provide at least 30 mm of space between Relays when two or more
Relays are mounted in a row.
30 mm min.
• 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
