3. Run a second metal conduit from the distribution panel box to the MC-5c back box. This
conduit will be used for the CT secondary wires. In a 24-channel installation, there will
be 48 #16AWG wires. The conduit should be sized to accommodate this.
4. The metal box must be grounded. Either a ground wire may be run and attached to one
of the box mounting screws, or the box may be grounded by the conduit. Securely
fasten one end of the grounding wire so that the screw cuts the paint on the back box.
Securely fasten the other end of the wire to true earth ground connection. When
grounding to the electrical conduit, use continuous pipes, bending when necessary
instead of using couplers.
Step 2: Connect optional communications wiring
1. If using the optional communications module, you must arrange for the proper type of
communication line to be brought to the communications module box. This could be a
telephone line, an RS-232 connection, or an RS-485 connection. This communication
line will connect to other equipment on-site. The details of this connection depend on
the particular installation.
2. Refer to detailed information for optional communication in the Appendix, page 76).
Step 3: Connect voltage taps
WARNING:
Power must be off when connecting these wires!
1. Locate the incoming feeder phase (hot) wires in the distribution panel. If color coded
wiring is not being used, tape the incoming feeder wires with colored electrical tape
according to phase, for identification purposes.
2. Tap the feeder connections with #12 AWG stranded wires. These voltage connections
can be made in any way that meets local codes and requirements. It is recommended
that some means be provided to disconnect these voltage lines to facilitate servicing of
the meter (fused disconnect, breaker, etc). Note: If fused, then no less than a 15A ‘Fast
Acting’ fuses must be used. The color of the insulation on these wires must match the
color of the feeder connections to which they are attached. If neutral is required, tap the
neutral connection with a #12 AWG stranded wire with white insulation.
3. Run the #12 AWG feeder phase tap wires through the conduit to the MC-5c back box.
Connect the wires to the MiniCloset-5c Fuse Block.
Step 4: Install and connect Current Transformers (CTs)
WARNING:
Power must be off when connecting these wires!
