CHAPTER 2 - INSTALLATION
2.1 INTRODUCTION
This Chapter provides the descriptions and procedures necessary to mount the BMS II 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 BMS II.
2.2 SITE SELECTION AND MOUNTING
Ensure that the site selected for installation of the BMS II 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 BMS II.
Mounting the BMS
AERCO recommends that the BMS II be wall-mounted using a sheet of plywood or other suitable
material. For easy viewing, the BMS II 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 BMS II 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 follows to mount the unit:
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 BMS II (see Figure 1-1) to provide access
to the slots for the two lower mounting screw locations.
3. Hang the BMS II on the installed top screw. Position the unit so it is level.
4. Mark the locations for the two lower screws.
5. Remove the BMS II and drill two pilot holes for the lower screws.
6. Replace the BMS II on the installed top-center screw.
7. Secure the BMS II to the wall by installing the two lower screws. DO NOT over-tighten the screws.
