Task 1 - Check the AC Supply and Grounding
It is important that the ac supply for the Access Power Solutions 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 I/O
Interface Board (see the diagram on page
81 for location).
‡
The High VAC alarm signal lines must be isolated from the ac supply by a
voltage-free relay contact.
