Page 3: Section 2 | Product Overview
AC to DC output into low noise and ripple, regulated 13.8-volt DC output for channel 1 and 13.4 Volt DC for channel 2. The EH-30 has a built-in battery backup and charging circuit with diode isolation for seamless transfer to battery if input power is disrupted. -
Page 4: Battery
Battery Connect your 12-volt DC battery using UL wiring to the EH-30 terminal marked Battery (+) and Battery (-). Be certain to connect Positive (+) to Positive (red) and Negative (-) to Negative (black). If two EH-30s are used in parallel, then connect the batteries as shown. -
Page 5: Section 4 | Maintenance
Section 4 | Maintenance Conductor Pretreatment All kinds of copper conductors can be clamped without treatment. DO NOT solder tin stranded conductors. The solder yields and fractures under high pressure. The result is increased contact resistance and excessive temperature rise. Additionally, corrosion has been observed due to the fluxes. -
Page 6: Section 5 | Warranty
DuraComm reserves the right to change, alter, or improve the specifications of its products at any time, and by so doing, incurs no obligation to install or retrofit any such changes or improvements in or on products manufactured prior to inclusion of such changes.
