2.3 Electrical Installation
2.3.1 Wire Connection
Conductors with a cross section of 0.08 to 2.5 mm² (AWG 28-12) can be connected using a CAGE CLAMP connection to achieve a vibration resistant, fast and maintenance free connection. To actuate the CAGE CLAMP enter an actuation tool in the opening above the connection. Following this, enter the conductor in the corresponding opening. The conductor is clamped securely with the removal of the actuation tool.

The clamping force adjusts automatically to the cross section. The full surface of the CAGE CLAMP pressure is applied against the conductor without damaging it. Conductor deformation is compensated for and self-loosening is avoided. The transition point between the conductor and the CAGE CLAMP is protected against corrosive influences. The connection can be made quickly and is also maintenance free, saving the costs for a periodic checking of terminal connections.
Two carrier rail contacts are responsible for the electrical contact between the grounded carrier rail and the controller, are fitted underneath the coupler/controller.
Attention
Ensure there is a perfect contact point between the carrier rail contacts and the carrier rail.
The carrier rail must be grounded.

Electrical Installation
2.3.2 Change fuse
Some Power supply modules of the WAGO-I/O-SYSTEM 750 are equipped with a fuse holder. To isolate the modules to the right of the power supply, the fuse can be removed from the fuse holder. For this insert a screw driver into one of the slits available on each side and lift the holder.

The fuses can be removed from or inserted into the holder with the fuse holder cover and push the fuse holder pushed back into the original position.
