2. ACS INSTALLATION
2.1 INTRODUCTION
This Chapter provides the descriptions and procedures necessary to mount the ACS and
connect all boiler plant units and applicable sensors. Guidelines are also provided for
connection of an EMS or BAS being used with the system. Refer to the wiring diagram provided
in Appendix E when making all wiring connections to the ACS.
2.2 SITE SELECTION AND MOUNTING
Ensure that the site selected for installation of the ACS provides the following:
Access to single-phase AC power from 110 to 240 VAC, 60 Hz nominal
Sufficient clearances to permit maintenance and setup/operational tasks on the ACS.
2.2.1 Mounting the ACS
AERCO recommends that the ACS be wall-mounted using a sheet of plywood or other suitable
material. For easy viewing, the ACS controls and display should be at eye level. Mounting is
accomplished using three screws (not provided). The spacing for the three screws are indicated
on the rear of the ACS in millimeters. Figure 2-1 shows the rear of the panel enclosure and also
indicates the required spacing for the three mounting screws in inches. Proceed as shown
below, to mount the unit:
Mounting the ACS Controller
1. First install a screw on the mounting surface at the top center location shown in
Figure 2-1. Leave a space of approximately 1/8 inch between the mounting surface
and the head of the screw.
2. Remove the wiring compartment cover from the front of the ACS (see Figure 1-1) to
provide access to the slots for the two lower mounting screw locations.
3. Hang the ACS on the installed top screw. Position the unit so it is level.
4. Mark the locations for the two lower screws.
5. Remove the ACS and drill two pilot holes for the lower screws.
6. Replace the ACS on the installed top-center screw.
7. Secure the ACS to the wall by installing the two lower screws. DO NOT over-tighten
the screws.
