Load connection
Turn off the AC input power before making or changing any
rear panel connection, Ensure that all connections are
securely tightened before applying power. There is a
potential shock hazard when using a power supply with a
rated output greater than 60 V
Wire selection
Two factors must be considered for the selection of the wires:
•
Current carrying capacity -> Cross section area
•
Maximum wire length.
•
Insulation voltage
Wire cross section and length
Wire size should be selected to enable voltage drop per lead to be less than 1 V
at the maximum power supply current to prevent excessive output power consumption.
Suggested wire sizes are listed in the following table:
Wire Cross Section Area [mm2]
Resistivity [Ω/km]
Maximum cable length in meters to
limit voltage drop to be less than 2 V
(1 V per lead)

are discourage to be used for minimize power losses and
voltage drops. If values of Table 2 are used the maximum voltage to the load will be
limited to:
EASY-DRIVER nominal output voltage – maximum 20 V
EASY-DRIVER power supplies could be connected to the load with a single
insulation wires which have voltage rating of at least 60 V
