Introduction
Introduction
The Relay SG relays messages through the Silver Spring Networks’ 900 MHz wireless LAN
communications protocol. The relay is a signal repeater between a Access Point SG and various
Silver Spring Networks-equipped endpoint devices.
The Relay is enclosed in a weatherproof enclosure and is typically mounted on poletops.

Safety Information
WARNING!: Severe shock and explosion hazard! Touching energized parts can result in
massive equipment damage, and severe injury or death. Short-circuiting energized
parts will result in blinding flash and explosion. Opening and closing electrical circuits
can also produce dangerous and explosive arc flashes. Involuntary muscular reactions
associated with electrical shock may result in other injuries. Observe the following
safety guidelines.
Careful planning of every job is essential. Nothing should be taken for granted. Do not take
chances!
zRead and follow all approved policies and procedures provided by your employer associated
with the procedures in this manual.
zThe procedures in this manual must only be performed by qualified workers in accordance
with local utility safety practices, utility requirements, and applicable OSHA and NFPA
standards.
zThe information contained in this document is intended to aid qualified personnel, and is
not a replacement for the proper training required to make a person qualified.
zSilver Spring Networks assumes no liability for the customer’s failure to follow these safety
guidelines.
General Electrical Safety

Safety Information
National Electrical Manufacturers Association (NEMA).
Electronics Industries Association (EIA).
Insulated Power Cable Engineers Association (IPCEA).
zAmerican National Standards Institute (ANSI). Whenever possible, de-energize all circuits or
equipment before working on them.
zMaintain a minimum clearance of 10 ft. between line potential and all unqualified persons
at all times.
zKeep unauthorized people out of the work area. Be especially cautious of children, who tend
to be drawn to work activity.
zDetermining if a circuit is OFF can be difficult in some instances. Check for circuit voltage
with an appropriate voltmeter before working on equipment presumed to have been de-
energized. Tiebreakers, double throw disconnect switches, automatic transfer switches and
emergency generators can supply power through an alternate circuit or from another
source.
z120V current can be just a lethal as higher voltages because current flow through a body
depends upon the body’s resistance.
zDo not trust insulation and/or weatherproofing on a wire as protection from shock.
zUse electrically insulated tools. Inspect portable electrical equipment or tools for defects
and remove any defective devices from service immediately. All portable electrical
equipment must have Ground Fault Circuit Interrupter (GFCI) protection.
zSelect the right tool for the job. Use tools properly. Keep tools in good working order.
zMake sure the work area is free of any flammable material. Flammable vapors can be
ignited by an arc flash.
zKeep the work area clean and dry. Cluttered work areas cause accidents and injuries.
zProvide good lighting in the work area. You cannot work safely if you cannot see what you
are doing.
zReport unsafe conditions or defective equipment to your immediate supervisor.
zHandle material carefully. Lift and carry properly.

Safety Information
Personal Protective Equipment (PPE)
zAlways wear Personal Protective Equipment (PPE), in accordance with OSHA and ANSI
standards.
zWear eye protection and electrically insulated gloves. Test gloves in accordance with ANSI
standards before use. Do not use gloves that do not pass appropriate test procedures.
zWear protective clothing such as long sleeve shirts and long pants made of flame resistant
materials.
zRemove all jewelry.
zDo not pass any objects to or from other persons not protected by insulating platforms or
tested, electrically insulated gloves.
Fall Protection
When performing work at any elevation:
zAlways use a fall protection system, in accordance with OSHA standards, whenever
performing work at any elevation.
zNever use conductors, guy wires, pins, or cross-arm braces, etc. to support your weight.
zWhenever using aerial lift devices such as hoists, man-lifts, vehicle-mounted work platforms
and overhead lifts, read and follow the manufacturer’s guidelines for safe and proper
operation.
zUse ladders and scaffolding only in accordance with the manufacturer’s guidelines and/or
according to OSHA standards.
zOnly use ladders made of non-metallic, non-conductive material. They should be the proper
size and type for the work intended. Inspect ladders for wear and breakage. Remove any oil,
grease, or other slippery materials.
zDo not set the ladder at too steep or too shallow of an angle. A rule of thumb is to stand
erect with your toes against the bottom rails of the ladder, with your arms extended straight
out. If you can set your palms on top of the rung that is at eye level, the ladder should be at
the proper angle. If a ladder angle label is provided, follow its recommendations.
zIf the ladder is to remain in place for an extended period, secure it at the top. The support
point at the top of the ladder should be at least 24 inches (60 centimeters) wide to maintain
Relay SG 7
Safety Information
support in the event of sideways movement. For jobs of short duration, have a fellow worker
support the ladder at the base.
zEvaluate all tasks to be performed from a ladder for potential fall hazards, such as complex
tasks or situations that require leaning from the side of the ladder.
The use of scaffolding or a work platform should be considered as an alternative solution in such
cases.
Shock Accident First Aid
zDo not touch the victim with your bare hands; use something non-conductive to separate the
victim from the energy source.
zCall for emergency medical help immediately. Keep the victim lying down, warm, and
comfortable until help arrives. Avoid moving the victim in case of injury to neck or back.
Position an unconscious victim on a side to let fluids drain.
zCheck the victim’s breathing and heartbeat. If properly trained, apply mouth-to-mouth
resuscitation and/or CPR if necessary.
zRemove constricting items from the victim, such as shoes, belts, jewelry, and tight collars;
they could cut off circulation if the victim experiences swelling.
zApply water or saline for a few minutes to any burns until the skin returns to normal
temperature. Do not attempt to remove clothing that is stuck to a burn. If possible, elevate
burned areas to reduce swelling.
zMake sure the victim receives professional medical attention, even if they feel fine. Electric
shock can cause heart failure hours after the shock is received.
