Wiring Terminals Section 2-2
â– Output Units
• The E5CN-H voltage output (for driving SSR) is not electrically isolated
from the internal circuits. When using a grounding thermocouple, do not
connect any of the control output terminals to the ground. (If a control out-
put terminal is connected to the ground, errors will occur in the measured
temperature as a result of leakage current.) E5AN/EN-H voltage outputs
(for driving SSR), however, are functionally isolated from the internal cir-
cuits.
• If high levels of noise or surge are imposed between the output terminals
of an SSR output, short-circuit faults may occasionally occur. If the output
becomes permanently shorted, there is the danger of fire due to overheat-
ing of the heater. Design safety into the system, including measures to
prevent excessive temperature rise and spreading of fire.
