Important Information
If the equipment is installed or used in a manner not specified in this
manual, then the protection provided by the equipment may be impaired.
Important Information
Before applying AC power (mains), make sure you have correctly selected
the voltage selector switch. In the case of the Fascia mount model this is
located under the removable cover at the bottom of the unit, 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 Zenith 140 with the terminals access cover removed.
An external switch or circuit breaker should be installed near to the Zenith
140 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 unit.
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.
