• Excessively long cable connections are not good practice. Try to keep
these lines to a minimum to reduce system voltage drop.
BATTERY, 0V
These 2 connections are to be connected to the battery.
• Ensure that the battery is connected with the right polarity. Although
reverse polarity will not harm the battery, power supply or the load, no
backup of the load will occur during a power outage.
• Consult battery manufactures data before use with the power supply.
• Excessively long cable connections are not good practice. Try to keep
these lines to a minimum to reduce system voltage drop.
RELAY
The 2 relay connections are the floating alarm relay contacts.
• Connect these pins to any circuit, which is required to be activated by
an alarm condition. The 2 pins become shorted when an alarm
condition occurs.
• These pins must not be connected to mains circuits or any other
hazardous voltage circuits.
Cabling
AC Cabling:
A cable size of 0.75mm
2
(18AWG) is recommended.
DC Cabling:
A minimum cable size of 0.75mm
2
(18AWG) is
recommended
for
BCE5.
A minimum cable size of 1.5mm
2
(16AWG) is
recommended
for
BCE4
Note, maximum size of cable to output connector is 2.5 mm
2
or 12AWG
DC load cables must be sized to carry the maximum full load current and
not exceed the system volt-drop requirements.
