3.2 Interlock in control cabinet

A thermostat can act as a temperature
limiter if interlock function is provided by
electrical circuitry. Below are two
examples for interlock circuitry.
In any case, valid standards (e.g.,
DIN EN 50156 / VDE 0116-1 and valid
local standards) must be observed for
design of electrical interlocking circuitry.
