Handling

■ Flat type socket

● Mounting method of relay

1) Match the direction of relay and socket.

2) Insert both ends of the relay firmly, all the way in.

3) Press the hooks in the direction of the arrows to attach the relay securely.

● Removing method of relay

1) Pull out the relay after fully releasing both hooks.

2) Take care not to push or spread the hooks more than necessary when installing or removing the relay, because doing so may cause deformation which will prevent the hooks from engaging with the relay, or the hooks may break.

■ Slim type DIN terminal socket

● Mounting method of fastening bracket

Install the fastening bracket before mounting the relay.

Press the fastening bracket into the terminal socket until it stops and check that the claw has engaged with the terminal socket.

● Removing method of fastening bracket

Pull out the fastening bracket while pressing the tab with a screwdriver or similar.

● Mounting method of relay

1) Match the direction of relay and terminal socket.

2) Insert both ends of the relay firmly, all the way in.

3) With the included fastening bracket, securely attach the relay.

● Removing method of relay

1) Pull out the relay after fully releasing fastening bracket.

2) Take care not to push or spread the hooks more than necessary when installing or removing the relay, because doing so may cause deformation which will prevent the hooks from engaging with the relay, or the hooks may break.

■ Slim type socket

● Mounting method of relay

1) Match the direction of relay and socket.

2) Insert both ends of the relay securely and all the way until both hooks engage with the mounting grooves.

● Removing method of relay

1) Pull out the relay while pressing and spreading the hooks.

2) Take care not to push or spread the hooks more than necessary when installing or removing the relay, because doing so may cause deformation which will prevent the hooks from engaging with the relay, or the hooks may break.
