Information on laying tray cables for exposed run (TC-ER)
The procedure for using conduits is described in this section. Instead of conduits, you can also
use tray cables for exposed run (TC-ER).
• When using tray cables for exposed run (TC-ER), select suitable cable glands and attach
to the enclosure opening instead of the conduit. When doing so, ensure that the
enclosure opening is sealed and no moisture can enter.
Procedure:
1. Break out the desired knockout on the Rapid
Shutdown Controller using a hammer and a
screwdriver When doing so, note that when using
the knockouts above and below in the lower
enclosure part, that the supplied adapter must be
used for conduits of the trade size 16 mm (0.5 in).
2. Where necessary, insert the supplied adapter in the position knocked out on the Rapid
Shutdown Controller and tighten from the inside using the counter nut.
3. Attach the conduit to the conduit fitting or onto the adapter in the Rapid Shutdown Controller
enclosure.
4. Lead the conductors up to the terminal blocks in the Rapid Shutdown Controller.
5. Strip off the conductor insulation by 8 mm (0.31 in).
6. In the case of fine stranded wire, provide each conductor with a bootlace ferrule.
7. Connect the conductors to the terminal blocks in
accordance with the assignment. To do so, insert
each conductor into the corresponding terminal and
tighten the screw on the terminal using a cross-head
screwdriver (PZ 2).
8. Place a jumper wire between the terminal X2 of the green LED and terminal X2 of the red
LED.
9. Ensure that all terminals are allocated to the correct conductors.
10. Ensure that the conductors are plugged completely into the terminals up to their insulation.
Useful hint: To release the conductors from the terminals, the terminals must be opened. To do
so, loosen the screw on the terminal using a cross-head screwdriver (PZ 2).
