7.2.2 COMPAX-M system network, NMD10 / NMD20 mains module

Short circuit connectors

A COMPAX-M drive system consists of one mains module and one or more drive controllers. The units are coupled with one another with flatband cables (see below). These are arranged behind the front plate cover of the power unit and the drive controller.

The power unit converts mains power (up to 3 * 500V AC) into DC current for the intermediate circuit.

The two connectors for connection to the bus systems are located on the front plate of the power unit. The connection assignment complies with the specifications for 2-cable remote bus.

The 24V DC control voltage required by the system network is supplied from the power unit.

A connector terminal on the front of the power unit is used for connecting the control and status signals (EMERGENCY STOP, readiness) which you can incorporate in the control of the entire system.

These signals and the bus lines are connected internally via a preformed doublesided flatband cable. These cables are included with the drive controller. The connectors which receive these connection cables are housed under the front plate cover of the mains module and the drive controller.

Attach a short circuit connector to the outgoing connector on the drive controller that is furthest away from the mains module. The short circuit connector (order No. 102-908000) is included with the mains module.

Installation arrangement

Before wiring up, always de-energize the unit.

Even once the mains supply has been switched off, dangerous levels of voltage can remain in the system for up to 5 min.

Wiring up the system network

The wires required for creating the system network are included in the delivery. Open the front cover (upper section of front side) by loosening the top right knurled screw and wire up the following:

!24V DC voltage supply.

!PE and DC current.

!Emergency stop, ready and bus signals with a terminating connector on the last unit.

From the mains module to the individual COMPAX-M.

When delivered, the terminating connector is located on the mains module.
