Electrical Connections

Connect a non earth leakage protected 10A 240v supply to Din Rail terminals labelled A & N, Connect
earth to the earth Din Rail terminal.
Conduits for power & control need to preferably come up through the base plate 'knockout'.
Connections to Control Board
Units are pre-wired
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 desired 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 24v AC supply control board terminals to power any
accessory as this can interfere with the control boards operation. (Blue Wires)
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 A.C / D.C @ 5Amps. If a 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 D.C @ 10 Amps.
