Caution, Warning and Danger Decals have been placed on the equipment
to warn of potentially dangerous situations. Care should be taken to keep this
information intact and easy to read at all times. Replace missing or damaged
safety decals immediately.
DANGER: Electrical Hazard
Disconnect electrical power before inspecting or servicing equipment unless
maintenance instructions specifically state otherwise. Ground all electrical
equipment for safety. All electrical wiring must be done by a qualified electrician in
accordance with local and national electric codes. Ground all non-current carrying
metal parts to guard against electrical shock. With the exception of motor overload
protection, electrical disconnects and over current protection are not supplied with
the equipment.

Pulsed Water Meter and Feed Scale Wiring
The pulsed water meters and feed scales require non-shielded 20 gauge twisted pair wire. This wire is
available through Chore-Time (part number 42208). When routing this wire in the house be sure to keep
the wire a minimum of 12" away from line voltage wiring. If there is a need for the sensor wire to cross
line voltage wires, cross them at a 90 degree angle to each as shown below.
Connect Pulsed Water Meters #2 through #9 to the IDM board terminals as shown in Figure below using
the Twisted Pair Wire. If a water meter not sold by CTB, inc. is used make sure that has a dry contact
output connection. DO NOT use a water meter that sends voltage out with every pulse. Note the correct
position of the IDM Board Dip Switches.

Using the blue and brown wires from the Feed Scales Connect Feed Scales #2 through #9 to the IDM
board terminals using Twisted Pair Wire (See Figure below). Note the correct position of the Dip
Switches. See Feed Scale Manual MT1811 for additional information if needed.
Airspeed Meter Wiring
The Airspeed Meter connects to the last digital input terminal on the IDM board using a three conductor
wire with a shield (See Figure below for Detailed Wiring). See Air Speed Meter manual for installing
the Wind Speed Sensor inside the house.
