clockwise until it’s tight.

Connect positive DC line to the ‘+24V’ terminal and the D C ground to the ‘GND‘ terminal.

FUSE Replacement:

The fuse use on MT608 is:

BUSSMANN

Fast Acting, Glass Tube

Rating: 250VAC, 1A

Size: 5x20mm

Warning:

1. Make sure the power off before replace the fuse.

2. Do not replace the fuse with a different rating fuse.

2.2.2 Grounding Requirements

Chassis ground must be used. DC ground is not directly coupled to Earth ground internally. It is preferable not to ground DC negative return to chassis ground as poor site earths can introduce noise into a system, but if necessary an earth connection should be made, from the power supply return point to the central star earth point. Ground conductors should be as short and as large in size as possible. The conductors must always be large enough to carry the maximum short circuit current of the path being considered. Ground conductors should be connected to a tree from a central star earth ground point. This ensures that no ground conductor carries current from any other branch.

2.2.3 CE Requirements

To make an NP-610X comply with EMC directives, and to reduce susceptibility to electrical interference, a separate #14 AWG ground wire should be taken to the chassis ground terminal of the power connector. This ground connection should be run directly to the central star earth connection point (as recommended in most Installation Instructions).
