Product description
Auxiliary power supply.
QC-APSS-15
Its main function is to generate a voltage of +24 V DC,
required to feed the QC-DR-275-SS2 drive control circuits
and the QC-RPS-160-SN0 main power supply, connected
to the DC BUS. This voltage is supplied via the A18
connector, which is only accessible under the cover
located at the bottom of the module on the front of the
equipment. This auxiliary power supply includes
protection against output over-current, over-voltage and
short-circuits.
DANGER or prohibition symbol.
It warns about an immediate dangerous situation. Ignoring

WARNING.
The DC bus discharge period may extend for up to 10
minutes after the equipment has been disconnected from the
electrical mains. There is no assurance that there is no voltage in
the DC bus when the D7 led is turned off. Accordingly, never
handle the DC bus even when the D7 led is turned off. Always
ensure that there is no voltage in the DC bus before handling the
equipment.
