Electrical Installation - Speck pumps Badu EcoM3V Installation, Operating And Service Manual

Electrical Installation

1. The pump motor must be securely grounded inside the motor control box. (See Figure 2.0)
NOTE: Do not connect to electric power supply until unit is permanently grounded.
2. Wire size must be adequate to minimize voltage drop during the start-up and operation of the pump.
See Table 1.0 for recommended wiring sizes.
3. Insulate all connections carefully to prevent grounding or short-circuits. Sharp edges on terminals
require extra protection. To prevent the wire nuts from loosening, tape them using suitable, listed (UL,
ETL, CSA) electrical insulating tape. For safety, and to prevent entry of contaminants, reinstall all
conduit and terminal box covers. Do not force connections into the conduit box.

1. Remove the three screws holding the top control enclosure onto the motor. Carefully lift the top panel
and turn it over to expose the inside terminal box. See Figure 2
2. The terminal box is supplied with a 1/2" -14 NPS threaded hole. Use only liquid tight fittings in order
to protect the electronics and the motor.
CAUTION: Failure to use liquid tight fittings will void the warranty.
3. The right side of the terminal block will be marked ground, L2, and L1. See Figure 2
4. After running L1, L2, and ground wire from conduit, connect the L1 to the opening directly across
from the orange wire on the terminal block. See Figure 2
5. Connect L2 to the opening directly across from the white wire on the terminal block. See Figure 2
6. Connect the ground wire to the opening directly across from the green/yellow wire on the terminal
block. See Figure 2
7. Carefully fold all wires inside the terminal box and place the top control panel back on top of the
terminal box.
8. Tighten the three screws into the terminal box while applying light pressure to the top control enclosure.
DO NOT OVER TIGHTEN.
9. The Badu EcoM3 - Variable Speed is a 208-230 volt pump. Make sure the correct voltage is supplied
(refer to the motor plate). Note: If the motor exceeds 250 volts the pump will not start from the Off/Stop
position.
