Important Information
Before applying AC power (mains), make sure you have correctly selected
the voltage selector switch which is located to the left and above of the
mains supply input terminals, as illustrated in the Terminal Connections
Detail drawing.
Please note that all units are supplied set to 230 volts AC for safety reasons.
Never operate the blackbox with the cover removed.
An external switch or circuit breaker should be installed near to the
blackbox to allow the supply to be removed during installation and
maintenance. In addition, the relay contacts should also have a means of
isolating them from the blackbox..
Interconnecting cables must be adequately insulated for IEC 664 Category II
installations. Strip back
30 mm of the outer insulation of the cable. Strip
5 mm of insulation from the end of each conductor. Twist all exposed
strands of the conductor together. Insert the stripped conductor into the
terminal block as far as it will go and tighten the terminal block screw.
Ensure that all strands are firmly clamped in the terminal block and that
there is no excess bare conductor showing, and no stray strands.
DON’T FORGET
Make sure you move the voltage
selector switch to the correct
position for your supply.
