RSD switch Installation

Wiring the switch inside the Rapid Shutdown (RSD)
enclosure
A ) Open the front face of the RSD by loosening the two screws on the
front face.
B ) Create wiring conduit in the top/bottom portion of the enclosure. There
are knock outs provided for this.
C ) Screw in 12AWG wires to terminals marked 1,2,3 and 4 of the switch.
Torque values can be found in the below table.
D ) Screw in 8-14 AWG wire to the Ground bar within the enclosure.
Torque values can be found in the below table.
E ) Draw the wires out through the conduit which has been created in the
enclosure.
F ) Secure the switch to the rear plate of the enclosure by torquing the
screws as indicated in gure 3. There are 2 screws to be torqued. The
screws can be found in the RSD kit.
G ) Fit the front face and torque the screws. Torque values can be found in
the below table.
H ) The torque rating of each of these wires/screws are as below:
S.No Point of Torquing Torque (Nm)
1 Terminal 1,2,3,4 1.8
2 Ground 0.8-1.4
3 Front cover 1.5
4 Screws to secure Switch 0.6

Mounting the RSD
A ) Identify a location which is near the Enpower smart switch to mount
the RSD. Please note that Enpower and RSD cannot be more than 200
ft apart.
B ) There are 2 mounting points on the back plate of the enclosure. They
are marked by red boxes in Figure 4 below.
C ) Installers can use any type of mounting as long as they are not
exceeding the diameter of each xing point.
D ) It is recommended that installers use #8 screw, with a minimum rec-
ommended length of 1.5 inches. The type of screw is to be determined
by installer based on where they wish to mount the RSD.

Connect wires from RSD and Enpower
A ) Connect the cables connected from Terminal 1 and 2 of the RSD to the
yellow portion of the cable header assembly (Figure 2) from NC3 and
crimp it.
B ) Connect the cables connected from Terminal 3 and 4 of the RSD to the
yellow portion of the cable header assembly (Figure 2) from NC4 and
crimp it. Refer to Figure 5 and table below.
C ) Connect the cable from the grounding bar to the Ground bar in
Enpower.
D ) Ensure Cables are properly sheathed and are not lose or exposed to
environment.
