NFB or fu se.
Swit ching ON/OFF the primary sid e of the
elect ro ma gnetic cont act or c an run the integ ra ted
elevat or dev ic e ON/ OFF, but frequent switc hing
is a cause of machine failure. Do not swit ch ON/OFF
more than once an ho ur. Do not use the electromagnet ic
cont act or as the power switc h fo r the int egrated
elevat or drive; doing so will s horte n the lif e of the
in tegrate d eleva tor drive.
When the main po wer supply capacit y is greate r
tha n 500k VA, or when it switc hes into the phase
