Table E. Requirements to Wire Power for Optional Heater Blanket
EH4700L and EH5700L: To determine the wire gauge to use, add up the wattages for the different accessories inside your
enclosure.
CAUTION: There are two ways to supply power to the camera - when the power requirements for the camera and enclosure’s
accessories are the same (for example, if the camera and accessories use 24 VAC), and when the power requirements for
the camera and the enclosure’s accessories are different (for example, if the camera uses 24 VAC and the accessories use
120 VAC).
If the camera uses the same power as the accessories, add the wattage of the camera to wattages of the accessories. Wire
power for the camera and accessories through pins 15 and 16 of the 37-pin connector.
If the camera uses different power than the accessories, wire power for the camera through pins 9 and 14 of the 37-pin
connector. Wire power for the accessories through pins 15 and 16 of the 37-pin connector.

* WARNING: To prevent damage to the wiper, AC high to turn on the wiper (pin 25 of the 37-pin connector) must come from the same
circuit that provides power to the wiper (pin 15 of the 37-pin connector). This is because the wiper and the on/off control share the same
AC neutral (pin 16). See Figure 10.
EH8106L: Power for the camera and heaters are separate. Refer to your camera manual for the camera wattage to
determine the size of wire to use. Wire camera power through pins 9 and 14 of the 37-pin connector. The heaters use a total
of 80 watts; wire through pins 15 and 16 of the 37-pin connector.
