ELECTRICAL CONNECTIONS
Operators:
Connect the 3 phase motor wires to the motor terminals plus earth and cable shield to the earth terminal. The
motor is connected in Delta configuration and the motor links have been set for this connection at the factory.
The cable shield has to be connected to earth at both ends.
Connect the 3 low voltage limit switch wires to the terminal strip provided.
The common limit switch wire goes to the centre terminal.
CONNECTION TO CONTROL BOARD:
Supply
Connect a non-earth leakage protected 10A 240v supply to Din Rail terminals labelled A & N
Connect earth to earth terminal.
Motor Wires
Connect the shielded motor cable to Inverter terminals. Connect earth and shield to Earth Stud.
Control
Connect low voltage limit switch wires to limit switch terminals on circuit board. Note the common terminal and
open/close terminals for motor one and motor two. Connect the shield (if used) to earth.
Control Inputs
The P.E, OPN and STP inputs require a normally closed switch contact and therefore should be shorted to the COM
terminal if not used. This is done via bridging links already on the circuit board (bottom left corner) The CLS, OSC and
PED inputs require a normally open switch contact and therefore should be left unconnected if not used. All the switch
inputs of this control board including the limit switch inputs require a switch contact only. Do not connect any
switches which provide a voltage to the control board as this will damage the control board. If the inputs are 12/24v or
has long wiring associated with it use an IM-1 module to isolate it from the control board’s input. The IM-1 is available
from the manufacturer.
Powering Accessories
Accessories which require a 24v AC supply can be powered from the transformer output used to power the control
board via the isolated 24v AC supply which is connected to the DIN rail terminals as labelled. However, the
transformer’s current capacity must be checked to allow for the extra power required by the accessories. Never use
the supply connected to the 24vAC supply terminals to power any accessory as this can interfere with the control
boards operation.
Locks & Lights
Use the lock output terminals on the din rail to switch the 12 volts to an electric lock (if fitted). The load
switched by the lock output terminals must not exceed 30v AC / DC @ 5Amps. If an electro-magnetic lock is
used, change one wire on the control board lock output to the normally closed output. Use the light relay
module (if fitted) to switch the applied voltage to a light. The load switched by the light relay module must
not exceed 240v A.C / 30v DC @ 10 Amps.
