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.
