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
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 the supply is 115V AC.
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.
