TRANSFORMER CASE MUST BE GROUNDED. TRANSFORMER WILL BE SHIPPED WITH A JUMPER CONNECTING SECONDARY CENTER TAP TO CASE. USER MUST PROVIDE APPROPRIATE GROUNDING OF SECONDARY CIRCUIT. FOR APPLICATIONS ABOVE A 20% DUTY CYCLE, CONTACT ROMAN MANUFACTURING FOR ASSISTANCE.
NOTE* The secondary terminals of this device
0.260 [6.6] X 45° Chamfer
are intended as an electrical connection only. Applications must be designed to minimize any forces applied to the secondary terminals, this can be accomplished by transferring forces to a structural member.

For more information
Notes • These curves are based on rated water flow of 7.5 L.P.M. (2 G.P.M.). • Maximum water in temperature of 30°C. • For applications about a 20% duty cycle, contact RoMan Manufacturing ® for assistance. Rectifier Rating: % Duty Cycle is based on shortest time from beginning of one weld to the beginning of next weld. On time/(On + Off time). Transformer Rating: % Duty Cycle is total “On” time in one minute.
