WARNING! The surfaces of regen supply module system components become hot
when the system is in use.
Safety instructions
Pressing the STOP button in the control panel or sending an external stop
signal does not disconnect the power feed from the regen supply module to the
intermediate circuit because the diodes in the supply module conduct
electricity even when no control signals are given.
Do not control the regen supply module with an AC contactor or disconnecting
device (disconnecting means); instead, use the control panel or external
commands via the I/O board of the regen supply module or a fieldbus adapter.
The maximum allowed number of charging cycles of the DC capacitors (i.e.
power-ups by applying power) is one per two minutes. The maximum total
number of chargings is 100000 for frame sizes A and B, 50000 for frame sizes
C and D.
When the control location is not set to local, the stop key on the control panel
will not stop the regen supply module.
