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 Fascia units are set to 115 volts AC with a 200mA fuse
fitted, and all Wall units are supplied set to 230 volts AC for safety
reasons, and a 100mA fuse fitted as standard.
Never operate the Ultra 3 with terminal access exposed.
An external switch or circuit breaker should be installed near to the Ultra
3 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 3.
Interconnecting cables must be adequately insulated in accordance with
local regulations. 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.
