Table 2.1 shows terminal description for VPO10.
Table 2.1 – Terminal description for VPO10.
NOTE
All cables used for connecting VPO10 with PROFIBUS-PA network must be shielded to avoid
interference or noise.
Conduits used for power cables must be assembled in order to avoid water entrance in the device
terminal block. Conduit screws must be sealed according to specific area required standards.
Non-used electrical connection must be sealed with appropriate cover.
Figure 2.7 shows the correct installation for conduit, in order to avoid the entrance of water or any
corrosive material that may cause damage to the device.

Terminal Description
Power Terminals - PWR BUS 9-32 Vdc not polarized
Grounding Terminals - 1 internal and 1 external
Communication Terminals – PROFIBUS-PA communication with configurator
Terminals 1, 2 and 3 – Current (4-20 mA) or discrete outputs, configurable
Terminal – 4 – Common – Negative of Power Supply
NOTE
It is extremely important to ground the equipment for complete eletromagnetic protection and
also to ensure the correct performance of transmitter on Profibus-PA network.
