Regular maintenance will extend the lifespan of
your equipment.
WARNING:
All maintenance operations inside the
PQstorI range of products should be undertaken
by a qualified electrician and performed only
when the equipment is off and de-energized.
Before touching the exterior of the module, check
for voltage between its terminals and the ground.
Internal components are isolated but damage to
the equipment could charge external surfaces
and cause serious harm when touched.
Before opening the module, always wait 20
minutes after disconnecting its power supply for
capacitors to discharge.
