3.1.10 Connecting the Timer
A
Turn-off the line voltage supply line.
B
Connect the three wires from the line voltage supply to the
terminal block (IN on the left) but do not connect any
outgoing wire (OUT on the right) to Wall Support.
C
Make sure that the “live” connector is the “hot” one:
a
Connect an AC voltmeter or a test light between the block terminal
“live in” and “ground”.
b
Turn line voltage supply “ON”. If full line voltage is measured (
lamp lights) the wiring is correct. If not turn line voltage
“OFF”, reverse “live in” and “neutral in” wires and repeat the
measurement; eventually the full line voltage should be read
between “line” and “ground” (test lamp lights).
c
Make sure no voltage is read between “neutral in” and “ground”; if
not check line voltage distribution.
D
Test the timer for full functionality keeping the output cables
disconnected so that power is not provided to the load.
