Control terminal specifications

Isolation of control circuits
The control terminals of the Commander SE drive are double-insulated from the
power electronics and single-insulated from the status relay contacts. Providing
WARNING
that the voltage on the status relay contacts does not exceed 110V, the control
terminals meet the requirements for SELV in EN50178. However, in the event of a
serious fault in the drive, the safety barriers could be breached. The installer must
ensure that the external control circuits are insulated from human contact by at
least one layer of insulation rated for use at the AC supply voltage. If the control
circuits are to be connected to other circuits classified as SELV e.g. a personal
computer, an additional isolating barrier must be included in order to maintain
SELV classification. Ensure that the correct fuses are installed at the drive input,
and that the drive is connected to the correct supply voltage.

Default configuration

All outputs (+24V, +10V, Digital output and Analog output) could be permanently
damaged if a negative voltage greater than -1V is applied to them.
