12/01 AWB2700-1428GB

A maximum of three bus modules for PROFIBUS-DP and CANopen

can be fitted between the power supply and CPU module.

Modules for the basic configuration: a, b, f, g

Bus modules: c, d, e

Mounting

The modules are supplied separately and must be fitted together.

Observe the order shown in Figure 1 and fit the base module first

of all on a horizontal mounting rail.

Fitting/removing modules

The back of the base module is provided with an eccentric plate.

Using a cheese head screwdriver, turn this plate so that it grips

underneath the mounting rail and secures the base module. The

front of the plate has number markings to ensure that it is posi-

tioned correctly.

X To fit the controller on the mounting rail, rotate the eccentric

plate until the longer slit is pointing to Position 1 (a Fig. 2).

X Hook the base module on the mounting rail (a Fig. 2).

X Turn the eccentric plate to the right until the base module is

secured firmly.

X Fit the power supply module and then the function modules.

The operator module is the last component to be fitted

(a Fig. 3).

Caution!

Only remove or fit modules with the power supply

switched off. Discharge yourself on any electrostatic

charge before touching a module.

Voltage peaks on the bus connector may cause

malfunctions or damage to the module.

The modules are removed as shown in a Fig. 4 and

Fig. 5.

Important!

When fitting the modules together, ensure that the socket

connectors fit exactly into the plug connectors.
