5.5 Connecting the CM5
Note:
- Do not lay high voltage cables along sharp metal parts or in sharp bends and do not
kink them.
- Keep high-voltage cables separate from low-voltage wiring.
- Keep high-voltage cables as short as possible.
1. Connect the earth wire to an earthing point.
2. If necessary, fit the spring connectors to the high voltage cable of the electrodes
Note: the 30 kV and 60 kV models have different connectors.
3. Screw the spring connectors of the charging electrodes into the high voltage connectors of
the generator. Cover unused outputs with the supplied caps.
4. If an “Anybus” module is fitted (back of the generator), it can be connected to the relevant
network. The connector depends on the protocol being used. Please refer to the manual
for the relevant Anybus module.
5. Connect the desired analogue I/O signals to the 25-pin sub-D connector. See section 5.6
to 5.112.
6. Set the [ 0 / l ] switch to the [ 0 ] position.
7. Plug the power cable into the IEC connector at the back of the generator.
8. Plug the power cable into an earthed wall socket or connect the power cable.
5.6 External control signals
On the back of the CM5 there is a 25-pin sub-D connector. This connector is intended for
various external connections. A summary of these connections is given below.
- Remote HV on/off
- Remote control of high voltage and current
- Readout of output voltage and current
- Status indicators
- Power supply for fieldbus sleep mode indication
5.7 Switching the high voltage on and off externally (Remote HV on/off)
The high voltage output of the generator can be switched on and off remotely by a machine or
PLC. In order to switch on the high voltage a voltage must be connected between pin 1 (+V)
and pin 14 (0 V). The voltage must be between 10 and 30 V DC. If no voltage is connected, the
high voltage is switched off. When the indicated voltage is connected to this input the high
voltage is switched on.
