A- Wiring instructions
Factory fieldbus (EtherNet/IP™) is connected to one of the 2 ports of the embedded Ethernet
switch (shielded M8/RJ45 cable).
Connect the “COVAL bus” using the provided bridge connectors or M8/M8 female cable for re-
mote modules.
24V DC power supply is connected to the rear connector of the last secondary module of the
island (or to the rear connector of master module if used as standalone LEMCOM) through the
COVAL bus termination cable.
Standalone secondary module or “Secondary only” island?
Refer to chapter VI for wiring and initial setup.
The LEMCOM vacuum pump must be used with power supply units that provide
a Protective Extra Low Voltage (PELV) and with an isolation of the supply voltage
according to EN60204.
This guide provides first-time users with information on wiring the different modules of a
LEMCOM island and on setting up the LEMCOM.

B- Consumption
The LEMCOM structure implies that all vacuum generators connected together on the COVAL
bus are electrically supplied by the same power source. The consumption table(left) must be fol-
lowed when calculating the required power supply voltage and amperage.
