The OmniCare EVC System Remote Units can be damaged if
either of the following situations occur:
• If Power is connected across the Data pair,
• If Power is reversed i.e. 0V and +V swapped.
NOTE: It is important to ensure each connection to the termination block
is made correctly and the screw terminals are tightened sufficiently.
The majority of problems encountered during commissioning are due to
loose, poor, or incorrect terminations on Remote Units that impair the
integrity of the ring.
