Installing the Interface Board
WARNING: Remove power from the inverter and wait at least five minutes before moving to the next
step. Open and remove the lower terminal cover. Confirm that the DC bus is fully discharged before
proceeding further. Also confirm that the external 115 VAC control circuits are deactivated and locked
out before proceeding. Otherwise, there is danger of electric shock, injury or death.
General
The 115VIF-DIN interface board may be used with either the WJ200 or SJ700 series of inverters. Follow the
appropriate installation instructions on the next pages for the particular model series in which you are installing
the board. The board’s 115 VAC-side wiring (from the pendant) and the corresponding AC input functions are
the same, regardless of which inverter series you are using.
AC Input Wiring – Connecting the Pendant to the 115VIF-DIN Interface Board
Connect the pendant 115 VAC input wiring to the terminals marked AC1 through AC5 on the 115VIF-DIN, with
NEU (neutral of the pendant control signals) as their common terminal. AC1 thru AC5 are connected to the
HOT side of the pendant control signals, coming from the pendant’s pushbutton contacts. The board’s AC input
terminal functions are as follows:
INPUT HOIST TRAVERSE

open-circuit forces inverter to MIN speed)

Up over-travel photo limit (NC sensor
input; open-circuit stops/prevents UP
motion – only DOWN motion is
possible)

Note 1: Inputs AC1 and AC2 functions are symmetrical with respect to direction in traverse applications. In hoist applications, however, AC1 must be
used for UP and AC2 must be used for DOWN.
Note 2: AC4 and AC5 inputs are intended to be used with over-travel limit sensors. These are secondary safeties, over and above N.C. limit switches
that would be wired in series with the AC1 and AC2 pendant inputs. They are “fail-safe” inputs, for use with N.C. type sensors. In this way, a
cut wire will have the same effect (inhibited of motion) as a sensor being triggered.
