INSTALLATION
All units are completely assembled, tested and inspected at the factory prior to
shipment. Upon receipt of the unit a visual inspection should be conducted to
detect any damage that may have occurred during shipment.
Inspection
The T350N-P should be mounted as practically as possible taking into account
display visibility, accessibility, etc. Ideally the T350N-P should be securely
mounted using
Physical
ONLY the supplied shock mounts on a stand positioning the unit
12-18” above the deck, clear of overhead pipes and as remote form the pump
motor as possible. Adherence to these guidelines will significantly enhance the
trouble free operation of the unit.
The T350N-P is designed to operate on the 12 VDC power system of the
transport and is “polarity insensitive”. Both the + and – power inputs should be
obtained in the pump control box. To facilitate testing without having to activate
the entire pumping system + input power should be derived from the unswitched
12 V input to the pump control box. Every effort should be made to keep the
T350N-P isolated as much as possible within the pump control box. In the event
transport doesn’t have a pump control box, as is the norm, 2 wires should be
routed to the trailer power junction box located at the front of the trailer. Do not
attempt to obtain power by splicing into the light circuit located near the
meter. Line drops and fluctuations may affect the operation. Additionally –

not connect a jumper from the T350N-P enclosure and the trailer
chassis and do not replace the chock mounts with solid “Look a-likes”
available in hardware store. They have solid mounting studs and are not
isolating studs as provided by the Sponsler Company.
The standard T350N-P signal cable is a 2 wire shielded cable with a MS3102
connector termination which is the industry standard interface for 2 pole pickup
coils. The shielding is single ended and should not be altered.
