Precautions for Safe Use
• Perform a function test every six months to
detect contact welding failures on contactors.
• It is the user's responsibility to make sure that
the entire system complies with standards.
• For safety reasons, two electrical switching
elements and two relays or contactors are
always necessary to detect electrical faults and
mechanical faults.
