LOCATION
The HR-RED can be installed indoors or outdoors.
MPORTANT
I
While the HR-RED electronics and battery are environmentally sealed and suitable for outdoor installation, the wire
terminals are not sealed from moisture. The unit, therefore, should NOT be installed in locations below grade level or in a
submersible environment.
INSTALLATION GUIDELINES
•
Always use enough cable wire. It is better to have a little excess than to go back and rewire.
•
If the HR-RED is replacing an existing RED or Read-o-Matic® display, do not use the existing interface wiring. Replace it
with new wire.
•
When installing the unit on buildings with a stone or masonry exterior, the use of masonry cleats and fasteners is
required. After determining the location, use a 3/16 in. carbide-tip masonry bit, and drill two mounting holes. Insert
masonry cleats and attach the HR-RED with round head screws.
•
After wiring, if the unit does not operate, check for bare wires touching each other.
•
If you secure the cable with staples, be careful not to pierce the outer sheath since this could short out the unit.
INSTALLING THE HR-RED
OTEE:
N
For best results the HR-RED should be mounted at eye level in an easily accessible location. Choose a location within
the limits of the meter cable. Maximum cable length between the meter and the HR-RED is 2000 feet.
1. Using the HR-RED base as a template, mark the mounting hole locations on the wall where the unit will be mounted.
2. Drill the mounting holes at the marked locations and secure the base to the wall. (Mounting hardware is
customer supplied.)
OTEE:
N
Avoid mounting the HR-RED on any type of loose siding since this may lead to wire breakage or other
potential problems.
3. Drill a 3/16 in. (5 mm) entry hole in the wall of the structure to accommodate the meter cable.
4. Pass the meter cable with the flying leads through the entry hole to the HR-RED.
5. Cut the meter cable to the proper length at the HR-RED, allowing sufficient cable for the connection.
OTEE:
N
Allow sufficient length so the cable hangs loosely, not taut, where it enters the building to eliminate the
possibility of rainwater running along the wire into the building.
6. Place the strain relief ring from the installation kit around the meter cable and secure it about 1-1/2 in. (38 mm) from
the end.
7. Use a cable stripper to remove the outer sheath of the meter cable, up to the strain relief ring, to expose the three
lead wires and the non-insulated shield wire.
8. Strip about 1/2 in. (13 mm) of insulation from the ends of the meter lead wires. Make sure you do not cut/damage the
wires or the wire insulation. At this point, you can cut off the exposed shield wire, even with the meter cable outer
sheath, to keep it out of the way.
9. Join the meter wires and the HR-RED wires using the connectors from the installation kit, one for each pair of wires.
