4.2 Load Connections (Ribbon Cable)
An additional method of connecting to the power supply is via a 14-way ribbon cable.
The ribbon cable must not leave the enclosure
A standard latching ribbon cable header is provided on the board, which may be used to connect to the load, and fault
signals. (See below.)
The ribbon cable should not be used alone for load power but always in conjunction with connections to
the load terminals 24V DC and DC RTN as described in 3.4.1 above.
Pin 1 = Negative
Pin 2 = Negative
Pin 3 = Negative
Pin 3 = Negative
Pin 5 = Positive 24V
Pin 6 = Positive 24V
Pin 7 = Positive 24V
Pin 8 = Positive 24V
Pin 9 = Battery disconnected
Pin 10 = Mains failed
Pin 11 = Battery low/High impedance
Pin 12 = Earth fault
Pin 13 = Charger fault
Note: pins 9 to 13 switches –ve with respect to Positive 24V and can supply a
maximum of 100 milliamps per output.
