FCC AND IC RFI STATEMENTS
FEDERAL COMMUNICATIONS COMMISSION
AND
INDUSTRY CANADA
RADIO FREQUENCY INTERFERENCE STATEMENTS
This equipment generates, uses, and can radiate radio-frequency energy,
and if not installed and used properly, that is, in strict accordance with the
manufacturer’s instructions, may cause interference to radio communication.
It has been tested and found to comply with the limits for a Class A computing
device in accordance with the specifications in Subpart B of Part 15 of FCC rules,
which are designed to provide reasonable protection against such interference
when the equipment is operated in a commercial environment. Operation of
this equipment in a residential area is likely to cause interference, in which case
the user at his own expense will be required to take whatever measures may be
necessary to correct the interference.
Changes or modifications not expressly approved by the party responsible
for compliance could void the user’s authority to operate the equipment.
This digital apparatus does not exceed the Class A limits for radio noise emission from
digital apparatus set out in the Radio Interference Regulation of Industry Canada.
Le présent appareil numérique n’émet pas de bruits radioélectriques dépassant les limites
applicables aux appareils numériques de classe A prescrites dans le Règlement sur le
brouillage radioélectrique publié par Industrie Canada.

CHAPTER 2: Introduction
2. Introduction
Transient surges can enter electronic equipment
through any pathway provided. Even if a facility has a
reliable AC power protection system in place, transient
surge energies generated within a building by sources
such as inductive load switching, ground loop currents,
and electrostatic discharge are clamped by the power
protector into the communication ground, damaging
expensive communications hardware.
The Multiport Hub Protectors guard equipment
networked at distances greater than 30 feet (9.1 m) and
for use in high lightning areas. They give added security
to electronic devices with extremely low tolerance for
voltage rises or ground loop energies. The surge
protector comes in 4- (SP530A-R2), 8- (SP531A-R2), and
12-Port (SP532A-R2) versions. Figure 2-1 illustrates the
front and side views of the available models.
The protectors guard 100BASE-T Ethernet, RS-422,
RS-485, or RS-423 interfaces. You can configure them
to incorporate solid-state thyristors or avalanche diode
technology with high-speed clamping of less than
5 nanoseconds. Combined into a compact interface
unit, the devices exhibit an extremely fast response time
of less than 5 nanoseconds.

The hub protectors’ interface connectors are available
in a standard configuration that protects all pins. Units
can also be specifically configured to protect any special
pin configuration or expanded to protect up to 12 ports
in a single package. Call Tech Support for details.

CHAPTER 3: Installation
3. Installation
To install the protector, insert it in series on the
incoming communication lines at the equipment to be
protected’s I/O port. Connect the protector’s ground
wire directly to the equipment’s grounded metal chassis.
CAUTION
For the protector to be effective, connect the protector’s
grounding wire directly to the metal chassis of the
equipment being protected. For best results, keep the
ground wire as short as possible. The equipment chassis
must be connected to earth through a grounded AC power
receptacle. Install protection units at both ends of the data
cable for effective protection.
