Important Information
The rear metal case of the fascia unit must be connected to earth via the
earthing stud located on the rear of the unit, see drawing above, using wiring
to meet local requirements.
Before applying AC power (mains), make sure you have correctly selected
the voltage selector switch, as detailed in the preceding pages.
Please note that all units are supplied set to 230 volts AC for safety reasons,
and a 100mA fuse fitted as standard.
Never operate the Ultra 5 with terminal access exposed.
An external switch or circuit breaker should be installed near to the Ultra 5
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 Ultra 5.
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.
