Installation Sheet

DS98-24 surge protector is used for the 'secondary' protection of the 24 V networks against the surge voltages creating by lightning. DS98 is equipped with safety disconnection, indicator and remote signal. The disconnection will be indicate by the turn on of the red led in the front. Very compact, the DS98-24 surge protector must be installed close by the equipment to protect, downstream a 'primary' surge protector. DS98 provides both a common and differential mode protection.
