Task 1 - Check the AC Supply and Grounding
It is important that the ac supply for the RM3-340/440 dc power system includes the correct
levels of protection.
Step 1 - High ac voltage protection at the site
1
Check if the ac voltage is expected to exceed 275V (L-N or L1-L2).
2
If so, then it is strongly recommended that an external high voltage protection
unit (HVPU) be installed. This will automatically disconnect the ac at high
voltage and reconnect it at normal voltage.
3
Install the HVPU as in the following diagram.
4
Connect the High VAC alarm output to one of the Digital Inputs on the GPIO
terminal block of the EFX48 e-Fuse unit (see the diagram on page 151 for
location). Then configure this Digital Input as the High VAC alarm by following
the instructions on page 102.
The High VAC alarm signal lines must be isolated from the ac supply by a
voltage-free relay contact – note that this is NOT contained within the
EFX48 unit.
