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.

As easy to mount as 1, 2, 3, these revolutionary battery switches allow you to wire
from the front. Never has installation been so easy and cabling so accessible.
With their shared interconnection height, EZ-Mount battery switches “cluster”
directly with the Pro Installer Busbar Range, resulting in the fastest, most compact
installations. All ratings and footprint of the EZ Mount Switch match those of the
corresponding Pro Installer 770 series standard mount switch, offering the same
high quality functionality, but with optimized, easy surface mounting.
1. Fit base
2. Add wiring
3. Clip on actuator
EZ Mount Installation (Surface Mount Only)
1. Disconnect battery positive leads at the batteries for safety
2. Choose mounting location on a fl 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 details on next page for Actuator
removal.
5. Drill holes and screw switch base into position
6. Connect cables to studs ensuring that batteries and loads are
correctly fi 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 fi 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
