11. MPM, MOVTEC PROTECTION
MODULE
The MPM utilises a high energy Neutral to
Earth spark gap to provide robust protection
against earth potential rise problems. Care is
required to ensure co-ordination of this device
if any other voltage limiting device is
connected either upstream or downstream in
the Neutral to Earth circuit. Contact your
local agent for further information if
other N-E protection devices are
installed and co-ordination may be
affected.
