terminal connection block. The line and ground connections to the terminal block are depicted in
Figure 1.
Your NCAT Asphalt Content Tester may be wired either directly through a conduit system or by
using a power cord and plug. Electrical wiring should conform to your local electrical code
requirements.

Electrical Conditions in the EU
Electrical Conditions for operating the furnaces in the EU:
The furnaces are intended for use at a network supply with a maximum system impedance of Zmax=
0.02 Ohm at the point of connection, according to EN 61000-3-11 clause 6.2.2. The user has to
ensure that the device is operated on a network supply that meets these requirements. If necessary, the
system impedance can be confirmed by the energy supplier.
Exhaust Installation Tips
1. Select a location to minimize exhaust length. We recommend an exhaust length of not more than
10 feet.
Do not operate the 220-240 volt NCAT Asphalt Content Tester on 208 volts. Your
test results will be negatively affected by the lower voltage. Consult with your supplier
if this is the case.
Failure to connect the exhaust port to an appropriate exhaust system will result in
smoke and gases entering the work area. Without the connection, gases and smoke
will escape from the furnace.
Do not connect the exhaust port to tubing less than 3" in diameter or otherwise
restrict the exhaust flow from the furnace. Also, do not connect the tubing directly to
an external fan or otherwise increase the velocity of the exhaust flow from the
furnace. Either restricting or increasing the exhaust flow from the furnace may
damage the furnace or reduce its efficiency.
