Peter -

Depending upon the equipment classification and country for deployment, MOVs
can be connected to protective earth.  Rather than repeat what is already

If your customer's situation is critical, you may want to consider a review
of key target markets for possible immediate deployment, and await re-design
for a more complete market entry.
