4.2 REMOTE UNIT INSTALLATION
Danger: Wet conditions increase the potential for receiving an electrical shock when
installing or using electrical power equipment. To avoid electrical shock, never install or use
the electrical equipment in a wet location.
Danger: Do not look into the end of the fiber optic cables. Exposure to laser radiation may
result. Do not assume that the laser power is turned off or that the fiber optic cable is
disconnected at the other end.
Danger: Use extreme caution when working with high voltage AC power. Ensure all power
is disconnected before working on power circuit.
Caution: Always make sure there is sufficient cable length to permit the routing of the fiber
optic cables to prevent the cable damage. The optic cables may be damaged if bent or
coiled too tightly.
