Also see Publication 471-2000, General
Installation and Wiring Guidelines for a
complete list of recommended tools and
supplies for MTU Installation.
Installation Procedure
There are two parts to this procedure.
First, the MTU must be wired to the IMAC
Pulsimatic Transmitter (IPT). Once this is
complete, you can then install the
Pulsimatic Transmitter onto the American
gas meter.
Wiring the MTU to the Pulsimatic
Step 1 – Unpack all of the components
required to install the IPT. This will
generally include the IPT itself, gasket
and a hardware kit that includes (2 each)
brass threaded rods, stainless flat-
washers and hex nuts.
Step 2 - When wiring to the IPT, support
the IPT off of the work surface on the
outside (topside) of its base so that
pressure is not applied to the center drive
shaft. Remove the cable clamp (screw)
from inside the base.
Step 3 – Trim the stripped ends of the
MTU cable to ¼” or slightly shorter. When
inserted into the terminal block, only a
small amount of bare wire should be
visible. Bare wire should not extend
beyond the walls of the terminal block.
This will present a shorting potential.
Step 4 – Feed the MTU input cable
through the sealtight strain relief in the
base of the IPT. Loop the cable so that
stripped ends of the wires can be easily
inserted into the terminal block screws.
The screws should already be open
enough. Place cable clamp over the wire
as shown.
Step 5 – Insert the BLACK and WHITE
wires into the COM terminal screw.
Tighten the screw.
Step 6 – Insert the RED wires into the NC
BLU terminal screw. Tighten the screw.
