Chiller Installation Instructions
Installing M2M Gateway
Prior to installing any Intelligent Equipment components, power
must be removed from the unit. Power must be removed at
the breaker panel serving the unit, and proper lockout/tagout
procedures should be followed for the duration of the install.
After removing unit power at the breaker panel, the installer
must verify the absence of power at the unit using a multimeter.
Only if power has been veried absent, should the technician
begin the install. The retrot kit is shipped with the M2M
gateway shipped loose.
The M2M gateway must be installed inside the unit control
panel. The installation location will vary depending on the unit
model and size of the control enclosure (see Figure 1 through
Figure 5 for correct component locations on AGZ and AWV
models). On AWS models, locate IE Hardware as space allows
within control enclosure. Figure 6 and Figure 7 provide the
typical layout of AWS small and large enclosures. On WMC
chillers, only the M2M gateway and gateway power supply
are used. Locate these components within the unit control
enclosure as space allows. Figure 8 shows a typical install
for WMC. For AMZ chillers, eld verify component locations.
Begin by positioning the M2M gateway on the backplane of
the enclosure and marking the screw holes. Next, drill pilot
holes, through the marks just created, using a 7/64" drill bit.
Finally, attach the M2M gateway to the backplane using (4) of
the provided #6 sheet metal screws (5/16" head). Install the
ring terminal on one end of the M2M ground conductor under
one of the(4) sheet metal screws (Figure 9). The M2M ground
conductor has ring terminals at both ends. Termination for the
other end of this conductor is described in the section entitled,
Connection of M2M and EMM to Ground on page 18.
