6 Assembling and installing
Only specialised personnel should be
allowed to assemble and install the device.
6.3 Installation
Always make the electrical connections
with the power supply disconnected and
the circuit-breaker open.
The receiver includes a safety device that
blocks pump operation at temperatures
lower than -10°C (10°F).
Configure protocol, baud rate and receiver address
via the DS1 dip-switches (Tab. 1, page 3).

Open the box of the WASPT device.
Connect telemetry lines A and B to connector J9
(WASPT board) as described in the relative manual.
We recommend using a twisted cable with minimum
section of 0.22mm²/0.8in² (AWG24).
If the receiver is connected to one of the head
communication channels RS-485, the line must be
terminated (SW8 column, Tab. 1, page 3).
Insert the DTWRX board in the specific J8 housing
and close the box of the WASPT device.
