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

EZ Mount Installation (Surface Mount Only)
1. Disconnect battery positive leads at the batteries for safety
2. Choose mounting location on a at surface close to the
batteries
3. Select pan head (or similar) screws for mounting - use either
M5 or 10g imperial (not included)
4. With Actuator removed, use the switch base as a mounting
template to mark the hole positions. (See separate
instructions for Actuator removal/tting)
5. Drill holes and screw switch base into position
6. Connect cables to studs ensuring that batteries and loads are
correctly tted
7. Ensure cables are secured to ISO/ABYC standards, and that
cables are supported so they are not placing unnecessary
strain on the battery switch studs
8. Check that spring washers are tted beneath nuts
9. Tighten the stud nuts to 13.5 Nm (10 lbf)
10. Slot the side panel(s) into the Actuator as required
11. Replace Actuator, ensuring that both switch base and
Actuator are both in their “OFF” positions
12. Lock the Actuator fastening screws
13. With switch in “OFF” position connect battery positive leads
at battery
14. Check switch operation
Check switch operation:
a. Loads have no voltage in “OFF” position
b. Loads have voltage from battery 1 in “1 ON” position
c. Loads have voltage from battery 2 in “2 ON” position
d. All connections are paralleled in “1&2” position
Fit Actuator at
0, 90, 180, or
270 degrees
