3.4.3 Battery Pack BU-5-1
The BU-5-1 can be installed underneath the 505U or beside it. The BU-5-1
uses the same type of enclosure as the 505U and is mounted in the same way.
The BU-5-1 has a “cable tail” which plugs into the 505U. The input wiring is
then connected to a socket on the BU-5-1.
The lid of the BU-5-1 can be rotated to suit installation.
A second BU-5-1 can be connected to the first in a similar manner. The input
wiring for the 505U is then connected to the socket on the second BU-5-1.
All plugs and connectors should be waterproofed with waterproofing
tape.
Check the label on the back of the BU-5-1 to make sure that it has been factory-set to
4.5Volts (model BU-5-1).
The BU-5-1 takes two types of batteries, Alkaline or Lithium. Alkaline Batteries have a temperature
