Compressor Installation
Installation of your compressor requires no special tools other than those
supplied in the Installation and Scheduled Maintenance Tool Kit.
Preparing the Compressor Input-Power Cable
To supply input power to the 8200 compressor requires the fabrication of a
600-volt power cable that has an SO-4 conductor, 600-volt rating neoprene
jacket and 14-gauge or 2.3 mm
2
wire. Proceed as follows:
1.
Prepare the input power cable by terminating each of the four
conductors with a #10 ring terminal. Follow the terminal
manufacturer's instructions to insure proper crimping.
2.
Disassemble the electrical terminal enclosure cover, mounted on
the compressor rear panel, as shown in Figure 3-1. Remove the two
screws securing the cover and lift it off.
3.
If necessary, back off strain relief screws.
