There is a danger of: • Uncontrolled movements • Permanent damage • Malfunctions Before performing any work on the M3000 ® automation system or M3000 ® modules, it is essential that the system is stopped and the power supply is disconnected. Therefore, all power supplies must be switched off, including those from attached peripherals such as externally supplied transmitters, programming devices, etc.! The signal cables of M3000 ® modules are connected over plug-in terminal strips that are inserted into the relevant connectors on the front of the module. 6.3.1 Plug-In Terminal Strips Plug-in terminal strips for the following methods are available from Moog: • Screw terminals • Spring loaded terminals All plug-in terminal strips are suitable for wire cross sections of up to 2.5 mm² (14 AWG). �-"11.8-Plug-In Terminal Strips" on page 121 6.3.1.1 Spring Loaded Terminals CAUTION When connecting a wire, insert the screwdriver only into the rectangular opening of the spring loaded terminal. If a screwdriver is inserted into the round opening for the wire, the spring loaded terminal might be destroyed. Spring loaded terminals make it easy to rapidly connect supply and signal cables. Procedure for connecting a wire: 1. Insert the tip of a screwdriver into the rectangular opening of the spring loaded terminal and press the screwdriver downward. 2. Insert the wire into the corresponding round opening. 3. Remove the screwdriver from the opening. The spring will hold the wire in place.

6.3 Connecting Signal Cables<br />

WARNING No work of any kind, such as mounting, removing, wiring,<br />

or repairs to the M3000 ® automation system or<br />

M3000 ® modules may be performed while the automation<br />

system or the modules are in operation!<br />

There is a danger of:<br />

• Uncontrolled movements<br />

• Permanent damage<br />

• Malfunctions<br />

Before performing any work on the M3000 ® automation system<br />

or M3000 ® modules, it is essential that the system is<br />

stopped and the power supply is disconnected.<br />

Therefore, all power supplies must be switched off, including<br />

those from attached peripherals such as externally supplied<br />

transmitters, programming devices, etc.!<br />

The signal cables of M3000 ® modules are connected over plug-in terminal<br />

strips that are inserted into the relevant connectors on the front of the module.<br />

6.3.1 Plug-In Terminal Strips<br />

Plug-in terminal strips for the following methods are available from <strong>Moog</strong>:<br />

• Screw terminals<br />

• Spring loaded terminals<br />

All plug-in terminal strips are suitable for wire cross sections of up to 2.5 mm²<br />

(14 AWG).<br />

6.3.1.1 Spring Loaded Terminals<br />

CAUTION When connecting a wire, insert the screwdriver only into the<br />

rectangular opening of the spring loaded terminal.<br />

If a screwdriver is inserted into the round opening for the<br />

wire, the spring loaded terminal might be destroyed.<br />

Spring loaded terminals make it easy to rapidly connect supply and signal<br />

cables.<br />

Procedure for connecting a wire:<br />

1. Insert the tip of a screwdriver into the rectangular opening of the spring<br />

loaded terminal and press the screwdriver downward.<br />

2. Insert the wire into the corresponding round opening.<br />

3. Remove the screwdriver from the opening.<br />

The spring will hold the wire in place.<br />
