Installation Instructions: IMPORTANT! 

Read before installing 

• 

It is recommended that electrical terminations and connections 
are carried out by a marine electrical technician.

• 

These battery switches are for isolation purposes and are not 
designed for switching under load.

• 

Ensure there are no circuits with high inductive loads directly 
connected to the switch in order to prevent any sudden in-rush 
of current which may cause damage to the switch.

• 

Although specially selected chemical resistant materials have 
been used, we recommend that for maximum product life only 
plastic safe corrosion inhibiting sprays are used.

•  Ensure all cables are sized correctly for the loads they carry. 

Please refer to www.bepmarine.com to calculate correct cable 

sizes.

• 

Ensure all electrical connections are correctly tightened to 
prevent any damage to the battery switch.

•  WARNING: Do not switch battery switch to off position while 

the engine is running.
