F and turn off at 60° F
3.5.1 Recommended Cable Size

3.5.2 Heater Kit Installation
To install the HK8000/HK8024, perform the following steps (refer to Figure 4):
1. Open the cover.
2. Attach the heater pads to each side of the tilt table bracket.
3. Press the PC board assembly into the four (4) holes provided in the tilt table
bracket.
4. Wire according to the diagram shown in Figure 5.
5. Close and lock the cover.
3.6 ELECTRICAL CONNECTION
After the cable has been routed, all wire connections should be made (i.e., video,
lens, camera power, heaters). A 6-position terminal block has been provided to
assist in this.
CAUTION:
When a single power
source is used for both the camera
and accessories, the camera power
consumption must be taken into con-
sideration when determining the wire
gauge. Also, make certain that all
electrical connections are done prop-
erly and meet electrical codes.
