LT1305-N-120 VAC Interface Card
for the Allen-Bradley Bulletin 1305 Adjustable Frequency Drive

Description
The 120 VAC interface card mounts directly to the control interface terminal block of the 1305 family of drives. It is suitable for all 460 Volt and 2 & 3 HP 230 Volt drives. It allows the use of 120 VAC control logic. The card allows Start, Stop, Jog, Enable and Reverse inputs with 3 other contact closure inputs SW1,SW2 and SW3.

Installation
1. Remove all power from the drive at L1, L2, L3 terminals.

2. Remove drive front cover. Verify that the bus NEON capacitor discharge light is off, before proceeding.

3. Connect power, ground and motor wires to the Power Terminal Block.

4. Loosen the screws on the Control Terminal Block to allow the Control Interface card to slide between the wire hold down clip and the terminal block.

Note: If the control logic signals originate from a triac or noise suppressed source, any off state leakage current must be reduced to below 3ma.. A 4.7K ohm, 10 Watt resistor installed between the input signal and L2 will usually reduce the leakage current to the appropriate level. This resistor must be mounted external the drive.

5. Install the larger card to the lower terminals marked 1 through 10. Install the smaller card to the upper terminals marked 11 through 20.

6. Terminate the control logic signals to the terminal block TB1 on the interface card. See Leaf Technology Drawing LT1305-N-120VAC for wire placement.

7. Make sure that no control logic voltage is present and apply power to the terminals L1, L2 and L3.

8. Program drive per instructions in the 1305 user manual (Publication 1305-5.1).

9. Apply power to TB1 control circuits.
