Ö Make sure that the power supply cables are not live. All internal connections are factory-
made.
Ö If necessary, cut off the excess cable length. Connect the 230V single-phase power supply
wires (2:4) to the terminals on the main switch (2:1), and the earth wire (2:5) to the adjoining
terminal (2:3). Make sure the equipment is correctly earth bonded (housing & associated
metalwork).
Ö Proceed with all other electrical connections depending on the equipment specifications
(control wiring, etc.).
Ö Route all cables via the cable entry holes and secure in the cable fastenings provided,
ensuring that they are held clear of the turnstile mechanism's moving parts.
Ö After the power supply from the remote isolator has been energised, test for correct polarity,
supply voltage and earthing, power up the equipment by putting the main switch (2:1) to the
ON position.
Note: When the turnstile is connected to an IT power system, a 2A two pole circuit breaker
must protect the 230V power supply.
