Power Relays

G7Z

335

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 sup-

plied 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.

• 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 x 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 auxil-

iary contact block catches in the

mounting hole on the Relay.

Removing

Slide

the

auxiliary

contact

block,

remove the auxiliary contact block tab
