Figure 3 – Use of BATT-BOX-65
27.
Where a dual box solution (PSE and CIE in separate enclosures) is used all cabling between the two
boxes should be routed to use separate case entry/exit holes from other cabling using suitable cable
glands to protect the cables
.
28.
Connect the two 12 V standby batteries in series using the single link cable provided. Connect the
negative
of one battery to the
positive
of the
other
battery.
CAUTION – DO NOT CONNECT the two remaining (free) battery terminals to each other
29.
Using the battery lead provided, connect the two white wires to the “Temp” terminals on the PSU
(polarity is not important) and the RED lead to “Bat+” and
the BLACK lead to “Bat
–“.
CAUTION:
Connect battery leads to PSU terminals FIRST - THEN
connect to the battery LAST.
30.
Connect the red battery lead to the free positive battery
terminal and the black battery lead to the free negative
battery terminal.
CAUTION – significant energy can be released from an SLA
battery. When connecting the last battery lead, take extreme
care to attach the cable ONLY to the correct terminal. Avoid
shorting it to any other terminal or conducting surface.
CAUTION
–
the supplied battery lead contains a temperature sensor – DO NOT attempt to modify this
lead in any way and do not use an alternative method of connecting the batteries.
31.
Reconnect the mains supply and verify that Fault LED #3 is off and Battery LED #2 indicates flashing or
constant Green.
2405ST only accepts batteries >=
22V
.
Note: Batteries as low as 19V may be connected, but this is NOT ADVISED as this could indicate damaged
batteries. To connect batteries as low as 19V, carefully disconnect one white temperature sensor wire from
the “TEMP” terminal block). This will induce a thermistor fault. Then wire the batteries to the terminals
