Listed or labeled equipment shall be installed and used in accordance with any instructions 
included in the listing or labeling. 

 

Over-current protection of the DC wiring must be provided as part of the system 
installation. 

 

All electrical work must be performed in accordance with local and national electrical codes. 

 

Use insulated tools to reduce the chance of electrical shock or accidental short circuits. 

 

Use Class 1 wiring methods for field wiring connections to terminals of a Class 2 circuit. 

o

 

Barcelona Class 2 terminals: WBJr, AUX, Current Transformers, BTS, CANBUS. 

 

The DC negative conductors are not connected (bonded) to the Barcelona chassis.   

 

Always verify proper wiring prior to energizing the Barcelona and Breaker Box. 

 

Torque all wiring and cable connections to the required torque values. 

 

Use only copper wires with a minimum temperature rating of 90°C. 

 

Properly mount the Barcelona and Breaker Box. 

 

Battery cables should be no less 

than 

#2/0 AWG

.  

 

BATTERY SAFETY 

 

Wear eye protection and avoid touching your eyes and face when working with batteries to 
keep any fluid/corrosion on the battery from contact with eyes and skin.  Have plenty of 
fresh water and soap nearby and thoroughly wash in case battery acid contacts skin, 
clothing, or eyes.  In the event of exposure to the eyes, flood them for at least 15 minutes 
with running water and seek immediate medical attention.  Baking soda neutralizes lead 
acid battery electrolyte and vinegar neutralizes spilled NiCad and NiFe battery electrolyte; 
depending on your battery type, keep a supply on hand near the batteries. 

 

Read and follow the battery manufacturer’s safety precautio

ns before installing the inverter 

and batteries.  Always verify proper polarity and voltage before connecting the batteries to 
the Barcelona and Breaker Box.  Once the batteries are connected, ensure the maintenance 
and charging requirements (i.e., charge voltage and charge rate) provided by the battery 
manufacturer are followed to extend the life of the batteries and to prevent damage to the 
batteries while charging. 

 

The battery bank should be installed in a clean, dry, ventilated environment that is 
protected from high and low temperatures.  If installed in a vehicle/boat, the batteries must 
be mounted upright (if using liquid batteries) and securely fastened.  The location must be 
fully accessible and protected from exposure to heat producing devices, and away from any 
fuel tanks. 

 

Batteries can produce explosive gasses, so install batteries in a well-ventilated area.  For 
compartment or enclosure installations, always vent batteries from the highest point to the 
outside.  Design the battery enclosure to prevent accumulation and concentration of 
hydrogen gas in pockets at the top of the compartment.
