LP3 - LP5 Linear DC Power Supply and Battery Charger
Installation Instructions (...continued from other side)
7. Battery Wiring Connect battery wiring to battery terminals of the Power Supply first, then connect
other end to battery set. Observe and verify correct DC polarity before connecting battery set. Incorrect
polarity will blow the BATTERY FUSE. See table above for maximum BatteryAH. Only use recommended
battery type - Yuasa, Power Sonic or equivalent sealed lead acid or gel cell.
8. Power Up Re-check all connections and apply AC power to the unit.

Power System Design Tips
Power Supply Total Current Draw
Add the operating current ratings for each device to be powered to
determine the expected continuous operating current required. Do not
exceed the specified maximum output current. If the output current value
is exceeded, the power supply regulator may overheat. The unit has built-
in thermal overload protection and the DC output will turn off if
overheating occurs.
CableResistance
When powering devices over considerable distances, the cabling resistance
may be so high that the voltage available at the device has dropped to an
unacceptable level. To prevent this from occuring, system cabling should
be designed with adequate sized conductors.
Power Distribution
Separately fusing output devices or groups of output devices greatly
reduces trouble-shooting efforts when shorts or output device abnormali-
ties occur. The larger the power supply and number of devices powered,
the greater the need for power distribution. BASE has a variety of power
distribution, interface and control products for a wide range of output
devices.
The information in this manual is believed to be accurate in all respects. However, BASE Electronics
cannot assume responsibility for any consequences resulting from the use thereof. The information
contained herein is subject to change and BASE Electronics may issue a revision to incorporate such
changes at any time.
