Grounding Outputs
By factory default configuration the FAST-Bi-1K5 minus terminal is grounded
to the Protective Ground (i.e. chassis, Mains-Earth terminal and all metallic parts
composing the box) through a fuse, Earth Fuse, which is accessible from the rear panel.
Under this configuration, the Output Terminals are not floating and cannot be connected
to Protective Ground.
If one of the output terminals is accidentally conducting to the Protective Ground
a fault will be triggered resulting in PS output disable. Refer to Earth Fuse (section
3.7.5) and Earth Leakage (section 3.7.6).
To allow output floating operation, it is sufficient to remove the Earth Fuse from
the fuse-holder and set the PS for Floating operation.
When the PS is configured to operate in floating mode either the positive or
negative output terminals can be grounded. Always use two wires to connect the load
to the PS regardless of how the system is grounded.
Models shall not float outputs more than ±200VDC
above/below chassis ground.
