2.2 Electrostatic Discharge (ESD) Handling
Procedure
Magnetrol’s electronic instruments are manufactured to
the highest quality standards. These instruments use
electronic components that may be damaged by static
electricity present in most work environments.
The following steps are recommended to reduce the risk of
component failure due to electrostatic discharge.
• Ship and store circuit boards in anti-static bags. If an anti-
static bag is not available, wrap the board in aluminum
foil. Do not place boards on foam packing materials.
• Use a grounding wrist strap when installing and removing
circuit boards. A grounded workstation is recommended.
• Handle circuit boards only by the edges. Do not touch
components or connector pins.
• Make sure that all electrical connections are completely
made and none are partial or floating. Ground all equip-
ment to a good, earth ground.

2.3 Mounting
The Model 960 level switch may be mounted in a variety
of positions as shown in Figures 2 through 5.
Pump
Protection
Proper orientation of the transducer gap will facilitate
maximum performance in difficult applications. When the
Model 960 is mounted horizontally, the transducer gap
must be turned vertical to allow proper drainage of liquid
out of the gap. The wrench flats on the mounting nut are
aligned with the transducer gap; therefore, proper trans-
ducer mounting can be achieved by aligning the mounting
nut flats in a vertical orientation. See Figure 4.
Low Alarm
When installing a Model 960 switch in a nozzle or pipe,
the transducer gap must extend into the tank at least one
Figure 2
inch beyond the inside tank wall. Refer to Figure 5.
Typical Mounting Orientations
Screw transducer into the opening using a wrench on the
transducer mounting nut flats. If flanged, bolt unit to mat-
ing flange with proper gasket. Use thread tape or suitable
pipe compound on the threads. Do not over-tighten.
