Page 19: Two-Phase Power Operation
External Input Protection The NI PS-14 is tested and approved for branch circuits up to 20 A. External protection is required only if the supplying branch has an ampacity greater than 20 A. In some countries local regulations might apply, so check local codes and local requirements. -
Page 20: Operation In A Sealed Enclosure
(for example, with cable conduits) by more than 30%. Proper installation clearance for the NI PS-14 is 40 mm on top, 20 mm on the bottom, and 5 mm on the left and right side when loaded permanently with full power. If the adjacent device is a heat source, 15 mm clearance is recommended between the NI PS-14 and the adjacent device. -
Page 21: Service Parts
Service Parts The NI PS-14 does not contain any serviceable parts. If an internal fuse trips, it is caused by an internal defect. If damage or malfunction occurs during operation, immediately turn the power off and send the NI PS-14 to NI for inspection. -
