INSTALLATION

Inspection

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. If the packing
case is damaged, notify the local carrier at once regarding his liability. A report should be made to the distributor.
Carefully remove the equipment from the packing and inspect for damaged or missing parts.

Physical

The T650N Flow Converter should be mounted as practically as possible taking into account display visibility,
accessibility, etc. Ideally the T650N should be securely mounted using ONLY the supplied shock mounts on a stand
positioning the Flow Converter 12-18” above the deck, clear of overhead pipes and as remote from the pump motor as
possible. Although the T650N enclosure integrity is watertight at manufacture, adherence to these guidelines will
significantly enhance the trouble-free operation of the unit.

Electrical

The T650N 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, + power input should be derived from the unswitched 12V input to the pump control box.
Every effort should be made to keep the proximity of the Flow Converter’s input power leads to the pump motor’s
winding leads as isolated as practically possible within the pump control box. In the event a transport doesn’t have a
pump control box, as is the norm in CO

, 2 wires should be routed to the trailer’s power junction box located at the

front of the trailer connected to the 12 VDC accessory or Light Circuit.

DO NOT ATTEMPT TO OBTAIN POWER BY SPLICING INTO THE LIGHT CIRCUIT LOCATED NEAR THE METER:
LINE DROPS AND FLUCTUATIONS MAY AFFECT THE UNIT’S OPERATION.

DO NOT CONNECT A JUMPER FROM THE T650N ENCLOSURE TO THE TRAILER CHASSIS AND DO NOT
REPLACE THE SHOCK MOUNTS WITH SOLID “LOOK ALIKES” AVAILABLE IN HARDWARE STORES; THEY
HAVE SOLID MOUNTING STUDS AND ARE NOT ISOLATING STUDS AS PROVIDED BY THE SPONSLER
COMPANY.

Signal

The standard T650N signal cable is a 2 wire shielded cable with an MS3102 connector termination which is the
industry standard interface for 2 pole pickup coils. The shielding is single ended and should not be altered.
