Safety Instructions
1.1 Warnings and Safety Summary
The equipment described in this manual contains high voltage.
Exercise due care during operation and servicing. Read the safety
summary below.
!
1.1.1 Safety Summary
The following safety precautions must be observed at all times during operation, service, and
repair of this equipment. Failure to comply with these precautions, or with specific warnings
elsewhere in this manual, violates safety standards of design, manufacture, and intended use of
this product. HPS/RFL assumes no liability for failure to comply with these requirements.
Ground the Chassis
The chassis must be grounded to reduce shock hazard and allow the equipment to perform
properly. Equipment supplied with three-wire AC power cables must be plugged into an
approved three-contact electric outlet. All other equipment is provided with a rear-panel
protective earth terminal, which must be connected to a proper electrical ground by suitable
cabling. The location of the protective earth terminal on the HPS/RFL™ GARD Pro™ system
is shown below. Refer to the wiring diagram supplied with the unit for additional information on
chassis and/or cabinet grounding.
A protective earth stud at the lower right rear of the HPS/RFL GARD Pro system chassis is the
main ground for the HPS/RFL GARD Pro system.

Do not Operate in an Explosive Atmosphere or in Wet or Damp Areas
!
Do not operate the product in the presence of flammable gases or fumes, or in any area that is
wet or damp. Operating any electrical equipment under these conditions can result in a definite
safety hazard.
Keep Away from Live Circuits
Operating personnel should never remove covers. Component replacement and internal
adjustments must be done by qualified service personnel. Before attempting any work inside
the product, disconnect it from the power source and discharge the circuit by temporarily
grounding it. This will remove any dangerous voltages that may still be present after power is
removed.
Unrestricted operator access is only permitted to the front of the unit when hazardous voltage is
applied. It is the responsibility of the installer to restrict access to the rear terminal blocks where
hazardous voltage may exist.
Do not Substitute Parts or Modify Equipment
!
Because of the danger of introducing additional hazards, do not install substitute parts or make
unauthorized modifications to the equipment. The product may be returned to HPS/RFL for
service and repair, to ensure that all safety features are maintained.
Read the Manual
!
Operators should read this manual before attempting to use the equipment, to learn how to use
the equipment properly and safely. Service personnel must be properly trained and have the
proper tools and equipment before attempting to make adjustments or repairs.
Service personnel must recognize that whenever work is being done on the product, there is a
potential electrical shock hazard and appropriate protection measures must be taken. Electrical
shock can result in serious injury, because it can cause unconsciousness, cardiac arrest, and brain
damage.
Throughout this manual, warnings appear before procedures that are potentially dangerous, and
cautions appear before procedures that may result in equipment damage or service outage if not
performed properly. The instructions contained in these warnings and cautions must be followed
exactly.

1.1.2 Additional Warnings
WARNING!
On initial installation, ensure that all modules are fully seated into connectors before powering
on the unit.
WARNING!
Follow all your company’s policies and procedures regarding the installation of AC powered or
DC powered equipment. If there is a conflict between any procedure in this manual and your
company’s safety rules, then your company’s safety rules must take priority.
WARNING!
Individual double pole disconnects must be installed between the building or station battery
supply and the HPS/RFL GARD Pro system power supply(ies). This must be done for both the
main and back-up supply.
WARNING!
The power supplies used in this equipment utilize fuses on both input lines. Therefore, in AC
applications the neutral line is fused. When a fuse is blown on the neutral line the internal circuits
may be energized.
WARNING!
Your GARD Pro terminal may be equipped with comms modules that have fiber optic emitter
heads. Fiber optic emitter heads use a laser light source that produces invisible radiation. Fiber
optic communication systems are inherently safe in normal operation because all radiation is
contained in the system. It is possible during maintenance to expose the radiation by removing
or breaking the fiber. Staring directly into the light beam may result in permanent eye damage
and/or blindness. Never look directly into the light beam and be careful not to shine the light
against any reflective surface.
The laser source is a class I laser product which complies with applicable FDA, OSHA and ANSI
standards.
1.1.3 Additional Cautions
CAUTION
Any installation using an enclosed cabinet with a swing-out rack must be securely fastened to the
floor. This will prevent the cabinet from falling forward when the rack is moved outward.
CAUTION
This equipment contains static sensitive devices. Persons working on this equipment must
observe electrostatic discharge (ESD) precautions before opening the unit or working on the rear
of the chassis. As a minimum you must do the following: Use anti-static devices such as wrist
straps and floor mats.

Additional warnings and cautions appear throughout the manual, these warnings and cautions
must be followed exactly.
NOTICE
RFL products are not designed for safety critical direct control of nuclear reactors and should
not be used as such.
NOTICE
The use of ungrounded instruments such as hand-held voltmeters has been shown to generate
Electro-Static Discharge. Care should be taken when using such devices on test points internal
to HPS/RFL equipment. Specifically, the use of probes manufactured under the Pomona brand
is not recommended.
1.2 External Labels, Warning and Cautions
Note the position of the power supply label so that the delivered unit’s configuration may be
verified with how it was ordered.
CAUTION
TO PREVENT ELECTRICAL SHOCK
PROPER CAUTION MUSTBE EXERCISED WHEN SERVICING THIS EQUIPMENT
ALL TERMINALS ON THE REAR OF THIS UNIT MAY HAVE HIGH VOLTAGE
!
This device complies with Part 15 of the FCC
rules and regulations. Operation is subject to the
following two conditions: (1) This device may not
cause harmful interference, and (2) this device
must accept any interference including
interference that may cause undesired operation.
!
FOR YOUR SAFETY
THE INSTALLATION, OPERATION AND
MAINTENANCE OF THIS EQUIPMENT
SHOULD BE PERFORMED BY
QUALIFIED PERSONS ONLY.
