Operating instructions

M 8200

The connections are made by way of the two plug-in terminal

strips: conductor cross-section max. 2.5 mm

. Fig. 1 shows the

connection diagram of the M 8200.

The number of occupied terminals is determined by the select-

ed functions. The Startup/Restart Inhibit and Contactor Moni-

toring functions can be deselected separately by means of wire

links.

Depending on the function selection, the reset device and the

NC contacts of the external contactors need to be connected in

addition to the sensor, the power supply and the outputs. When

contactors are connected, appropriate arc suppression

elements must be used directly on the contactor coil. Fig. 2

shows the configu-ration of the M 8200 with a external reset

and contactor monitoring.

Terminals C 1, C 2, C 3, C 4 and D 1, D 2, D 3, D 4 have a load

capacity of 2.5 A..

Electrical Connections

Isolated plastic-sheathed cables

Outside the control cabinet the connected output cables of

protective device sensors that are not short circuit monitored

must be routed in separate plastic-sheathed cables, and the

wires of the switching outputs (signal lines to the contactors)

must be individually shielded and the shields must be

connected to 0 V in the control cabinet.
