Three Wire Connection - Siemens HES24 Manual Del Usuario

Step 6: Connect Electric - Flexible Conduit With Wires
Note:
Siemens recommends the range cord installation (previous page).

Three Wire Connection:

The Four Wire Connection is preferred, but where local codes and
ordinances permit grounding through neutral and/or conversion to
four wire is impractical, unit may be connected to the power supply
via a three wire connection.
1. Disconnect electrical power at the breaker box.
2. Remove the terminal block cover to expose the junction box
(See Figure A).
3. Remove the top nut, star washer, and round washer from each
post.
Note: DO NOT remove last round washer, last nut or internal wire
leads.
4. Place one terminal lug (packaged with this manual) on each
post. Replace the star washer and round washer and secure
with 20 inch pounds of torque.
5. Strip 3/8 inches of insulation from the end of each wire (See
Figure B).
6. Insert stripped end of white wire into the center lug on top of
the ground strap. Secure the clamping screw (See Figure C).
7. Insert stripped end of red wire into the left lug. Secure
clamping screw.
8. Insert stripped end of black wire into the right lug. Secure
clamping screw.
9. Tighten each clamping screw with the appropriate torque (See
Table 1 at right).
10. Properly secure flexible conduit at knockout panel on range
and at supply side junction box. The wiring is now complete
(See Figure D).
Four Wire Connection
:
(Preferred to three wire connection)
1. Disconnect electrical power at the breaker box.
2. Remove the terminal block cover to expose the junction box.
3. Remove the top nut, star washer, and round washer from each
post.
Note: DO NOT remove last round washer, last nut or internal wire
leads.
4. Remove screw from bottom end of ground strap.
5. Remove ground strap from center post. Discard.
6. Attach one terminal lug (packaged with this manual) through
hole below terminal block with ground screw.
7. Place one terminal lug (packaged with this manual) on each
post. Replace the star washer and round washer and secure
with 20 inch pounds of torque.
8. Strip 3/8 inches of insulation from the end of the wire (See
Figure C).
9. Insert the un-insulated grounding wire into the lug below the
terminal block.
10. Insert stripped end of white wire into the center lug. Secure
the clamping screw.
11. Insert stripped end of red wire into the left lug. Secure
clamping screw (See Figure D).
12. Insert black wire into the right lug. Secure clamping screw.
13. Tighten each clamping screw with the appropriate torque (see
Table 1 at right).
14. Properly secure flexible conduit at knockout on angel and at
supply side junction box. The wiring is nowcomplete (See
Figure E).
Note: DO NOT plug in range at this time.
Proceed to steps 7 and 8.
