Fuses
The mainframe fuse is located inside the mainframe. Refer to the mainframe Service Manual for information about
replacing the fuse.
Power Cord Installation
The power cord supplied with your mainframe may or may not include a power plug. Figure 2-1 shows the various power
plugs. Ring terminals are attached to one end of the power cord to facilitate mainframe installation.
Figure 2-1. Power Cord Plug Configurations
If your power cord will be directly wired into your location’s power system, installation must be done
by a qualified electrician and in accordance with local electrical codes.
To install the power cord, refer to Figure 2-2 and proceed as follows:
■ Position the strain relief connector, safety cover, rubber boot, and connector nut on the power cord.
■ Secure the ground wire to the earth ground stud.
■ Connect the neutral wire to the "N" input terminal.
■ Connect the line wire to the "L" input terminal.
Note Route the power cord wires upward from the terminal block. This allows room to install the safety cover.
■ Replace the safety cover and tighten the cover and strain relief screws.
Do not apply power to the mainframe until directed to do so in the Check-out procedure located in the
module User’s Guide.
