CAUTION
■
Precautions for Safe Use
Observe all of the following precautions to maintain safety.
1.
The Time Switch is not waterproof or oil resistant. Do not use it in
locations subject to water or oil.
2.
Use the following wire to wire the Time Switch: 600-V vinyl-
insulated wire (solid wire or twisted wire, copper), 14 to 24 AWG
3.
Do not connect more than two crimp terminals to each Time
Switch terminal.
4.
None of the Time Switch components are user-replaceable,
including the battery.
■
Precautions for Correct Use
Be sure that the capacity of the power supply is large enough,
otherwise the Time Switch may not start due to the inrush current
(approx. 3 A) that flows for an instant when the power to the Time
Switch is turned ON.
ON Current and Ambient Temperature
(Reference Values)
If the ON current is too large, the upper limit to the ambient operating
temperature must be reduced as shown in the following diagram.
Mounting Dimensions
Flush Mounting
•
Use a U-shaped mounting bracket to flush mount the unit.
Surface Mounting
•
Use a straight mounting bracket to surface mount the unit.
Track Mounting
•
Hook the upper part on the rear surface to the upper edge of the
mounting track and press the unit down.
•
To remove the Timer Switch from the DIN Track, pull
down on the yellow lever at the back of the Timer
Switch.
Wiring
Wiring From the Rear
•
Perform wiring from the rear of
the unit when the unit is flush
mounted.
Wiring From the Front
•
Perform wiring from the front of
the unit when the unit is track
or surface mounted.
Wiring Procedure
1.
Loosen the screw on the left
side of the front.
2.
Slide the upper part of the unit
approx. 15 mm upward.
3.
After the terminals appear,
perform wiring.
4.
Return the upper part of the
unit to the original position and
tighten the screw.
Note:
Screw tightening torque: 0.98 N·m max.
Tighten terminal screws to the specified torque of approx.
0.8 N·m (maximum torque: 0.98 N·m). Loose screws may
occasionally cause fires or malfunction.
The Time Switch contains a lithium battery (explosion-
proof). Do not disassemble the Time Switch, deform the
Time Switch under pressure, heat the Time Switch to
above 100
°
C, or incinerate the Time Switch. Doing any of
these may result in fire or battery rupture.
