Danger to life due to electric shock when touching exposed DC
conductors or DC plug contacts if the DC connectors are damaged or
loose
The DC connectors can break or become damaged, become free of the DC cables, or no
longer be connected correctly if the DC connectors are released and disconnected
incorrectly. This can result in the DC conductors or DC plug contacts being exposed.
Touching live DC conductors or DC plug connectors will result in death or serious injury due
to electric shock.
• Wear insulated gloves and use insulated tools when working on the DC connectors.
• Ensure that the DC connectors are in perfect condition and that none of the DC
conductors or DC plug contacts are exposed.
• Carefully release and remove the DC connectors as described in the following.
9. For STP 50-40 / STP 50-JP-40 (use of Sunclix DC
connectors): Release and remove the DC
connectors. To do so, insert a flat-blade screwdriver
or an angled screwdriver (blade width: 3.5 mm) into
one of the side slots and pull the DC connectors out.
When doing so, do not lever the DC connectors out,
but insert the tool into one of the side slots only to
release the locking mechanism, and do not pull on
the cable.
10. For STP 50-US-40 / STP 33-US-41 / STP 50-US-41 / STP 62-US-41 (use of Amphenol DC
connectors): Unlock the DC connectors using the corresponding unlocking tool and remove
(refer to the manufacturer manual for further information).
11. Ensure that the DC connectors on the product and those that are equipped with DC
conductors are in perfect condition and that none of the DC conductors or DC plug contacts
are exposed.
