Protect electronic equipment

outside the building

Electronic equipment outside the main building in ancillary

buildings, on site or in the field should also be protected.

CCTV cameras

Protect outdoor CCTV cameras with

protectors on the power supply, and

video cable (and, if relevant, telemetry

control line).

External buildings

If the UPS is housed in a separate

building with a separate earth, incoming

and outgoing supplies will need to be

protected. This is because most modern

UPS systems contain electronics that

make them vulnerable to being disabled

by transient overvoltages. To prevent

transient overvoltage damage to the UPS it must have a

protector installed on both its input and output (outgoing the

building). A protector will also need to be installed on the

power supply into the main building (2).

Data communication/telephone lines

Protection is also installed on mains

power, data communication and telephone

lines entering the neighbouring building.

Additional protection (not shown) may be

required within this building (whether it’s

a computer-controlled warehouse or

automated manufacturing operation with PLCs, drives and

computer controls).

Data & signal lines

Protectors are installed on CCTV video

cables from outdoor cameras to

prevent damage to the control desk.

A protector is installed at the network

hub to protect it from transients on

the between building data link.

Equipment such as our RF receiver,

with antenna (or satellite) links will

also need protecting.

Protect the power supply locally to

important equipment

Within the building transient overvoltages

can be injected on to the mains power

supply (downstream of the protector

at the incomer). Consequently, protectors

should be installed close to important

pieces of equipment.

CCTV cameras

Protect outdoor CCTV cameras with

protectors on the power supply, and

video cable (and, if relevant, telemetry

control line). The telephone PBX is

protected locally by a plug-in protector.

This illustration is designed to demonstrate the main aspects and

individual components of a system of Surge Protection methods. It is not

intended to represent an actual scheme conforming to a particular

code of practice. The drawing is not to scale.
