wiring terminal strip, which is located at the right side of the appliance.

NOTE: All internal electrical components have been pre- wired. No attempt should be made to connect electrical wires to any other location except the wiring box.

5.1 Main Power

The main power requires a 120-volt fused supply that is connected to the “main power” terminal strip. The over current protection must be sized as specified ( Figure 15).

The BMT2 pump (pump-mount units) requires a separate (additional) 120-volt fused supply connected to the pump terminal strip (also specified in Figure 15).

5.2 Field Wiring

Main Power: The main 120V field wiring panel is located on the right side of the unit, under the main power switch. Within this panel are the terminals for incoming 120V single-phase power clearly labeled on the right-hand side as “120V (L1)”, “NEUTRAL” and “GROUND”.

Pump Power: Also located on the 120V field wiring panel is the pump terminal strip. This strip is located on the left side (denoted as “120V L2”, “N2 (Pump mounted)” and “GROUND 2 (Pump Mounted)”).

External Pumps: External Pump: All non-pump- mounted BMT2 units have an internal (dry) contact rated for 20Amps. A field-supplied pump can be connected directly to this contact if it does not draw more than 20 Amps. If more current is required, a separate pump contactor must be installed.

To utilize this internal pump contact, supply 120 volt single-phase power to the terminal marked “120V (L2)” and supply the pump using the terminal marked “L2 LOAD (EXT. PUMP)”.

NOTE: This pump control is equipped with a delay on break typically set for 3 minutes, but can be adjusted between 0.1 and 10 minutes.

Field Interlocks: To install other field-wired devices to interlock with the boiler (tank stats, louver switches, flow switches, etc.), remove the jumper between terminals 3 and 4 and wire the device in series across these terminals. These terminals are located in the upper main control panel.

External Control Wiring: These terminals are located in the upper main control panel (see Section 5.3).

Optional Alarm Contacts: As an option, the Brute Deluxe is available with an alarm kit. This alarm kit contains a dry contact for up to 120V which is available within the 120V field wiring panel. These terminals will be clearly labeled "Alarm" and are rated up to 10 amps.
