Connect in series with the data communication or signal
line either near where it enters or leaves the building or close to
the equipment being protected (eg within its control panel). Either
way it must be very close to the systems earth star point. Install protectors
either within an existing cabinet/cubicle or in a separate enclosure.
If installing several protectors together these can be simultaneously
mounted and earthed via a CME kit.
Suitable accessories
Simultaneously mount and earth up to 4 of these protectors
on a CME 4, up to 8 on a CME 8, up to 16 on a CME 16 or up to 32 on
a CME 32 - click here for details.
Enclosures suitable for up to two (WBX 2/G) or three (WBX 3/G) protectors,
or a CME 4 and its associated protectors (WBX 4), CME 8 and protectors
(WBX 8) or one or two CME 16 kits and protectors (WBX 16/2) can be found
here.
