Precautions
Be sure to read the common precautions provided in Best Control Devices Catalog Version 17 before using the Relay.
■ 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
• The Relay can be mounted directly on a mounting rail (PTP) or a
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 sup-
plied or right after the power has been turned OFF.
The hot surface may cause burn injury.

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).

• 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 auxil-
iary 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.
