a) If possible, power to the electronic time switch
should be supplied from a phase different from
the one supplying power to the load.
b) INDUCTIVE-LOADS should have suitable VARIS-
TOR and RC network ( ) across the
supply terminals to reduce voltage spikes.
c) DC INDUCTIVE LOADS should have a diode
across their terminals to eliminate back EMF of
the inductor.
d) HIGHLY INDUCTIVE LOADS, especially fluores-
cent lights, may require a relay in which case (a)
and (c) apply.
e) IN HIGH LIGHTNING AREAS,a surge suppres-
sor should be installed.

Installation
MOUNTING
Surface mounting the talento 800 inside a control panel
or enclosure is accomplished with a standard DIN rail.
Place the two protruding guides, which are on the top
of the rear rail cutout slot, over the top lip of the rail;
then snap the bottom into place.
For stand-alone installation use a Grasslin indoor/outdoor enclosure.
The timer module can be removed from the timer housing for programming or change-out purposes.
WIRING
Make certain to connect only to the supply voltage
designated on the unit itself. Warranty will be void if
wrong voltage is applied. Connect wires to the screw
terminals in accordance with the wiring diagram shown
(use 12 to 22 AWG wire).
INSTALLATION CHECKLIST
1. The time switch should have its own independent
circuit for power supply.
2. Since all electronic instruments are sensitive to voltage spikes, close attention must be paid to the following:
