Note The tightening torque for E5CN-U is 0.5 N·m.
CAUTION
Tighten the terminal screws to between 0.74 and 0.90 N·m. Loose
screws may occasionally result in fire. (See note.)
Set the parameters of the product so that they are suitable for the
system being controlled. If they are not suitable, unexpected
operation may occasionally result in property damage or
accidents.
A malfunction in the Temperature Controller may occasionally
make control operations impossible or prevent alarm outputs,
resulting in property damage. To maintain safety in the event of
malfunction of the Temperature Controller, take appropriate safety
measures, such as installing a monitoring device on a separate
line.
A semiconductor is used in the output section of long-life relays. If
excessive noise or surge is impressed on the output terminals, a
short-circuit failure is likely to occur. If the output remains shorted,
fire will occur due to overheating of the heater or other cause.
Take measures in the overall system to prevent excessive temper-
ature increase and to prevent fire from spreading.
When inserting the body of the Temperature Controller into the
case, confirm that the hooks on the top and bottom are securely
engaged with the case. If the body of the Temperature Controller
is not inserted properly, faulty contact in the terminal section or
reduced water resistance may occasionally result in fire or mal-
function.
