SAFETY INSTRUCTIONS

WARNING!

 Read all safety warnings and all instructions. Failure to follow the warnings and 

instructions may result in electric shock, fire and/or serious injury. Do not plug in your parallel 

connection kit or electrical device until the following steps have been read and understood.

SAVE THESE SAFETY INSTRUCTIONS.

1. 

DO NOT operate in rain, wet or damp conditions, or with wet hands.

 The operator may suffer severe 

electric shock if the generator is wet.

2. 

If at any point the parallel connection kit becomes wet, wipe and dry the kit well before operation. 

Do not pour water on the parallel connection kit or use water to clean the kit.

3. 

Pay attention to extension cords and all wiring attached to the parallel kit. 

If any wires are under the 

generator or in contact with a vibrating part, it may break, causing a generator burnout and electric shock 

hazard. Properly replace damaged cords immediately.

4. 

Follow all necessary electrical grounding procedures for the parallel kit, connected generators, 

and related equipment. 

The parallel kit is designed to be grounded to provide a path of least resistance 

for the electric current, reducing the risk of electric shock in the event of a failure or breakdown. Failure to 

correctly ground equipment can cause serious injury or death.

5. 

DO NOT connect or disconnect parallel kit wires while the generator is running.

 Only turn on 

generators once the parallel kit wires have been properly connected.
