Connection details
IN+ : Input positive IN - : Input negative
OUT+: Output positive OUT- :Output
negative
Note: The input Voltage range is DC 10.00-80.00V.
80.00V DC is the maximum input Voltage limit.
Always ensure an adequate safety margin and
ensure that your OFF LOAD input supply Voltage
does not exceed the maximum allowed. Failure to
do so can result in considerable damage to the
unit.
Even though this module is designed with reverse polarity input protection and output short
circuit protection you must still ensure that connections to the unit are in accordance with the
connection details. If the Input Power Supply is connected to the output terminals then the unit
will be severely damaged.
The input must be DC Power only. AC or AC Mains supply 110 or 220V must NEVER under any
circumstances be connected to this unit. Apart from the immediate and potentially fatal risk of
electrocution this will cause major, irreparable damage to the unit.

M0-M9 Data Groups
M0 Data Group
The M0 Data Group is a special case. It is the power default Data Group. It should be noted that
any time an alternative Data Group is selected or any changes made to the existing settings then
M0 will be immediately overwritten with the newly selected data. In effect, M0 is always a
real-time duplicate of the currently selected Data Group and data values. It is also the data-set
that will be saved at power off and recalled at next power on. This happens automatically and
transparently with no input necessary from the user.
