The nVent ERICO System lightning
protection system requires no user
operation and is completely automatic
in operation.
• The nVent ERICO Dynasphere becomes
active only during storm activity.
• The system does not require any external
power requirements or replacement
components for normal operation.
• It is essential that the nVent ERICO
System be regularly maintained.
Maintenance should be undertaken:
• After each known strike to the nVent
ERICO Dynasphere
• At least once per year
• If any changes have been made to the
structure, whether they be structural,
antennae or building maintenance unit
additions, etc.
Use the maintenance record table below to
record the relevant details. These records
and manual should be kept in a safe place
near the installation.
Maintenance should be undertaken as follows:
Do not attempt maintenance during
potential lightning periods.
1. Check that the building is in the same
physical shape and that no additional
structures such as antennae, advertising
signs, satellite dishes, building
maintenance units or similar have been
installed within m ( in.) height of the
nVent ERICO Dynasphere.
2. Inspect the nVent ERICO Dynasphere to
ensure that it is not dented or physically
damaged in any way.
Operation and Maintenance
3. Inspect the finial tip on top of the nVent
ERICO Dynasphere to ensure that it is not
excessively burnt, deformed or missing. A
finial tip must be replaced if more than
mm (¼ in.) of the tip is missing.
4. Check that the FRP mast and lower
mast assembly is securely attached
to the structure and is placed in a
vertical position. Check that the guys
are secure and undamaged. Replace
if necessary. Check that all fastenings
are secure and tight.
5. If connected, check the structure bonding
cable from the upper termination or
mast base is securely connected to the
structural steel work.
6. Look for signs of damage to the nVent
ERICO Ericore downconductor (whether
by lightning, careless handling, vandalism
or other causes). Check that the
downconductor is inaccessible to people
and machinery.
7. Check that all labels and signs are still
attached and clearly legible. These
labels MUST be in place. Refer to the
section on Labelling.
8. Check that the nVent ERICO Lightning
Event Counter (LEC) is secure, and that
the display is registering a reading, then
record the reading.
9. Record resistance and continuity
measurements using Figures
