Part Number: 144-25079 (G+M 48VAC IF CARD)
Applicability: G+ Mini
Introduction: The G+M 48VAC Interface option card mounts directly to the control board
terminals (S1 – S7 and SC) on the drive. This card allows 48 VAC control logic circuits to
interface with the seven digital inputs (S1 – S7) with the G+ Mini control circuitry.
Receiving: All equipment is tested against defect at the factory. Report any damages, shortages
evident when the equipment is received to the commercial carrier who transported the equipment.
Warning: Hazardous voltage can cause severe injury or death. Lock all power sources feeding
the drive and the option card’s wiring in the “OFF” position.
Important: When handling boards always use electrostatic discharge (ESD) protection. Keep the
boards in the ESD bag as long as you can. Do not lay the board on any surfaces without ESD
protection. When handling, always hold the board from the edges and do not touch the
components. Before installing this option card, a technically qualified individual, who is familiar
with this type of equipment and the hazards involved, should read this entire installation guide.
Control Circuit Terminals:
The G+ M 48V IF CARD has seven optically isolated input terminals which can be used to
connect with the user 48 VAC devices. The interface card connects to drive terminals S1-S7 and
SC. The users 48 VAC input devices will then connect to terminals S1-S7 and X2 on the interface
card. Terminals S1 and S2 are factory set for the forward (up) and reverse (down) run
commands; however, they can be programmed for speed control and other functions like the
remaining terminals. Figure 1 shows the control terminal arrangement for the IMPULSE•G+ Mini
with the 48V interface card along with a simplified wiring diagram.

*Parameter functions and defaults change based on X-Press programming.
1. Disconnect all electrical power to the drive.
2. Remove the front cover for the drive. (Depending on
model, you may need to remove the protective cover
and discard – See Figure 2).
3. Verify that the “CHARGE” indicator lamp inside the
drive is off (It may take as long as 10 minutes for the
charge on the DC bus capacitors to drop to a safe
level).
4. Use a voltmeter to verify that the voltage at the
incoming power terminals (R/L1, S/L2, and T/L3) has
been disconnected.
5. Loosen the terminals S1 – S7 and SC on the drive
controller board.
6. Remove the G+ M 48V IF CARD from the ESD bag.
7. Connect your 48VAC interface devices to terminals S1-
S7, X2 on the G+M 48V IF CARD. (See Figure 1 and
Table 2).
8. Insert the G+M 48 VAC IF CARD into terminals S1-S7
and SC.
9. Tighten the terminals.
10. Reinstall the front cover.
