Installation Manual for PV Link and SnapRS

General Hazards

• Connecting  Generac PWRcell  to the elec

-

tric  utility  grid  must  only  be  done  after

receiving  prior  approval  from  the  utility

company.

• Only competent, qualified personnel should

install, operate, and service this equipment.

Strictly comply to local, state, and national

established by the National Electrical Code

(NEC),  CSA  Standard;  the  Occupational

Safety  and  Health Administration  (OSHA),

or  the  local  agency  for  workplace  health

and safety.

• Protection  against  lightning  surges  in

accordance with local electric codes is the

responsibility of the installer.

NOTE: 

Lightning  damage  is  not  covered  by

warranty.

• If working on this equipment while standing

on metal or concrete, place insulative mats

equipment  only  while  standing  on  such

insulative mats.

• Never work on this equipment while physi

-

cally or mentally fatigued.

• Any voltage measurements should be per

-

formed  with  a  meter  that  meets  UL3111

safety  standards,  and  meets  or  exceeds

overvoltage class CAT III.

PVRSE Warning

NOTE: 

SnapRS devices must be used in con

-

junction with Generac S2502 PV link to form a

complete PVRSS per NEC 690.12

This Photovoltaic Rapid Shutdown Equipment

(PVRSE) does not perform all of the functions

of  a  complete  Photovoltaic  Rapid  Shutdown

System  (PVRSS).  This  PVRSE  must  be

installed with other equipment to form a com

-

plete  PVRSS  that  meets the requirements  of

NEC (NFPA 70) section 690.12 for controlled

conductors outside the array. Other equipment

installed  in  or  on  this  PV  system  may

adversely affect the operation of the PVRSS.

It is the responsibility of the installer to ensure

the  completed  PV  system  meets  the  rapid

shutdown functional requirements. This equip

-

ment must be installed according to the manu

-

facturer’s installation instructions.

be used in a critical life support application. 
Failure to adhere to this warning could result 
in death or serious injury.

(000670)

WARNING

Hot Surfaces. Locate and install the PV Link so as to avoid 
inadvertant contact. When operating in hot weather the 
optimizer will become hot and could result in personal
injury.

(000155a)

WARNING

Electric shock. Only a trained and licensed electrician 
should perform wiring and connections to unit. Failure to 
follow proper installation requirements could result in death, 
serious injury, and equipment or property damage.

(000182a)

WARNING

Equipment damage. Only qualified service personnel may 
install, operate, and maintain this equipment. Failure to 
follow proper installation requirements could result in death, 
serious injury, and equipment or property damage.

(000655)

WARNING

Equipment damage. Never open the PV Link. The 
optimizer is factory-sealed and contains no field- 
serviceable parts. Opening the optimizer could result in
equipment damage.

(000669)

WARNING

Equipment damage. Never operate  PV Link in ambient
temperatures greater than 158° F (70° C). Operating  
PV Link in high temperature conditions will result in 
equipment damage.

Equipment damage. Connect only to REbus-compatible 
devices to the DC bus. Never connect to any other DC 
power source. Connecting to other DC power sources 
could result in equipment damage.
