Siemens Industry, Inc. 3617 Parkway Ln., Peachtree Corners, GA 30092
Installation (Figure 1)
1. Remove the enclosure cover from the case.
2. Remove the knockout in the cover.
3. Mount pilot device support bracket assembly with two
mounting screws in location
A (Size 1) or B (Size 2 and 3),
tighten screws to 25 lb.-in.
4. For pushbutton 3-wire control, make electrical connections
per Figure 2.
5. For the 2 and 3 position selector switches, make electrical
connections as shown in Figures 3, 4, 5, and 6.
6. Location of auxiliary interlocks may differ from diagrams,
therefore, markings on units should be followed.
7. Affix the appropriate legend label onto the cover next to the
pilot device.
Important! Prior to performing steps 1 through 13 verify that
all power is turned off to the pump control panel.
1. Examine each device on the panel for shipping damage and if
any is noted, notify carrier for claim. Do not apply power to
any damaged device.
2. Operate disconnect switch or circuit breaker with external
handle to verify operation.
3. Manually operate magnetic starter contactor to determine that
moving parts do not bind. Manual operation of the contactor
is performed by pressing on the movable contact assembly as
shown in Figure 1 for Class 87 and Figure 2 for 3RE48.
4. Verify that the supply voltage matches the voltage rating of the
pump panel.
5. Verify that the horsepower rating of the motor does not exceed
the horsepower rating of the pump control panel and the current
rating of the motor is within the adjustable range of the overload
relay. Set the FLA dial on the overload relay to the motor FLA.
Make sure the DIP switches are set to trip class 10 for pumping
applications. Refer to the overload elay instruction sheet
for details.
6. Install in conformance with National Electric Code – NFPA70
in the US or Canadian Electrical Code – CSA C22.1 in Canada,
and any applicable local electric codes.
7. Install the proper size dual element fuses in the disconnect
switch. The disconnect switch and fuse load block will accept
Class H, K, J or R fuses depending on the fuse holder. If the
available fault current of the supply is greater than 10kA, Class
R or J fuses must be used. Verify the available fault current of
supply does not exceed the interrupting rating of the fuses in
stalled and does not exceed the short circuit rating of the
pump panel controller.
8. If the pump controller includes an instantaneous trip breaker,
adjust the trip setting of the breaker according to the instruction
on the door label. Verify the available fault current of the
supply does not exceed the short circuit current rating of the
pump controller.
9. Firmly fasten enclosure to solid mounting surface with customer
supplied fasteners.
10. Install necessary grounding means and wire pump control panel
in accordance with wiring diagram supplied. Conduits installed
in knockouts at the bottom of the enclosure must be located
below all live parts. Conduit hubs or fittings installed on the top
or side walls of the enclosure must have a NEMA 3R rating.

11. Check that all wiring is secure and does not interfere with
proper operation of any devices.
12. Check that all wiring connections are tight, including
factory connections.
13. Make a final installation check of steps 1 through 12 and
remove any foreign material from the enclosure.
