1.3.2.3 Communication module
This module enables communication to various instruments:
• One Ethernet 10/100 Mbps port for communication with a server;
• One USB port (same function as the one on the front);
• One serial port for half-duplex RS-485 (TWS and Modbus RTU) or full-duplex RS-422 (Modbus RTU)
communication.
1.3.2.4 Power input
A 3-position removable female type screw terminal connector allows power input wiring. The ZPU-5000 unit
should be installed in compliance with national and local electrical standards.
1.3.2.5 Protection fuse
The ZPU-5000 acquisition unit is protected by a fuse accessible from outside the back panel. Replace only
with the same type of fuse: 3.15A / 250V slow-blow, 5x20 mm.
1.3.2.6 Protective conductor terminal
The protective conductor terminal on the rear panel must be connected to a grounding point in compliance
with local regulations. Grounding through the protective conductor terminal is essential for safety purposes. It
also provides better efficiency against ESD and EMI disturbances.
