To connect 24 VDC supply power to the analyzer, perform the following steps:
(Refer to
Figure 8)
1. Open the cover of the SpectraScan using a large, flat-headed screwdriver turn the latch ¼ turn
counter-clockwise, and open the cover.
2. Bring a 3 conductor, separately jacketed cable with 24V supply into the enclosure through the
conduit fitting. Make sure that the power is not on (wires are not live) at this point.
WARNING
Maintain Ingress Protection: The Servomex SpectraScan unit has been
tested to an Ingress Protection level of IP66, Type 4. In order to maintain this
rating, a suitable 1” conduit connector must be used that will not compromise
the existing IP Rating.
3. Strip the cable jacketing back and secure the jacketed portion of the cable to the anchor point
provided inside the enclosure using a cable tie. Be sure to leave enough slack in the cable so
the red and black wires reach the power terminal block on the main board and the green wire
reaches the ground lug on the enclosure wall.
4. Strip 10mm (0.4”) of insulation from the positive (red) and negative (black) leads of the cable,
and also from the ground (green) wire.
5. Connect the positive (red) cable to the positive side of the terminal block on the main PCB and
the negative (black) cable to the negative side of the input power terminal block.
6. Connect Earth Ground:
a. Connect the green wire to the earth ground lug on the enclosure wall.
b. Check the two factory installed ground wires, at both ends, for loose connections;
resolve any that are found. Ensure that both are secured to the enclosure anchor
point with a cable tie. The factory installed ground wires are:
i. PCB to earth ground
ii. Enclosure lid to earth ground
7. Close and latch the cover.
