Precautions
Mounting
When
two or more timers are to be mounted in line, provide a dis
-
tance of more than 5 mm between the two adjacent timers.
When
two or more timers mounted in line are to be continuously en
-
ergized
at the same time after the set time has elapsed, be sure to
limit
the carry current to less than 1 A.
When using the timers at an ambient temperature of more than
40°C,
be sure to reset the
timers immediately after the set time has
elapsed.
Wiring
When
wiring, employ a multi-core cable
having a finished outer di
-
ameter of less than 10.5 mm, or insulated (twisted) wires with less
than
a 3 mm outer diameter
.
ALL DIMENSIONS SHOWN ARE IN MILLIMETERS.
