CAUTION
For use of units in applications with temperature alarm
settings it is recommended to foresee a delay of 10
minutes for signalling the alarm in case the alarm
temperature is exceeded. The unit may stop for several

Keepthefollowinginmind:
▪ Ifstrandedconductorwiresarebeingused,installaroundcrimp

NOTICE
Precautionswhenlayingpowerwiring:
▪ Do not connect wiring of different thicknesses to the
power terminal block (slack in the power wiring may
causeabnormalheat).
▪ When connecting wiring which is the same thickness,
doasshowninthefigurebelow.
▪ Forwiring,usethedesignatedpowerwireandconnect
firmly, then secure to prevent outside pressure being
exertedontheterminalboard.
▪ Use an appropriate screwdriver for tightening the
terminal screws. A screwdriver with a small head will
damage the head and make proper tightening
impossible.
▪ Overtighteningtheterminalscrewsmaybreakthem.
