Power and DMX data cable layout
Figure 7 gives an overview of a suitable cable layout. The dotted lines represent AC power
circuits. The solid lines represent the data link.
Cables and cable glands
The power cable supplied with the product is 9.5 mm (0.37 in.) external diameter. The data cable is 6.5 mm
(0.25 in.) external diameter. If you install these cables in cable glands in the installation (when connecting
cables in external junction boxes, for example), make sure that the cable glands are designed to accept
these cable diameters.
The IPON
®
IP68-rated cable glands used for power and data cable entry into the fixture accept cable with 5
- 10 mm (0.2 - 0.4 inch) external diameter. If you replace a cable, install a new rubber seal or a complete
cable gland if the seal is not in perfect condition. If you use a cable with an external diameter that is not
within the range accepted, replace the cable gland with a suitably dimensioned item. Cable glands must be
rated IP68 and suitable for the cable diameter and application. New cable glands can be obtained from
Martin™ (P/N 13102000) or from electrical suppliers.
To replace an IPON cable gland:
1. Lock out power to the installation and allow it to cool for 20 minutes.
2. Loosen the dome nut in the existing gland to release the cable, then unscrew the gland from the rear
cover.
3. Remove the rear cover from the fixture, note connections and disconnect the cable from its terminals.
4. Slide the old gland off the cable.
5. Screw the new gland into the rear cover until it is tight enough to make a seal. Do not overtighten.
6. Pass the cable through the new gland and rear cover, then connect it to its terminals (with reference to
“Replacing the power cable” on page 13 or “Connection pinouts” on page 15 if necessary).
7. Reinstall the rear cover as follows:
a. Read“Managing humidity” on page 7.
b. Check that the seal is in perfect condition.
c. Place the seal and cover in position and drive the cover screws until they are finger-tight only.
d. Cross-tighten the screws evenly in a diagonal pattern, increasing torque gradually in stages to a
maximum torque of 8 Nm (5.9 ft.-lbs.).
8. Tighten the dome nut on the cable gland to seal the cable before applying power.
