The ceilometer is equipped with a grounding
connector at the bottom of the radiation shield for external grounding.
WARNING At the installation site,
a connection to a solid earth ground is mandatory for adequate lightning and transient
protection.
WARNING To minimize shock hazard,
the chassis and cabinet must be connected to an electrical ground. The ceilometer is
equipped with a three-conductor AC power connector. The power cable must be plugged into an
approved three-contact electrical outlet or the ceilometer must be carefully grounded to a
low-resistance safety ground.
The ceilometer is designed as protection
class I (safety grounded) electrical equipment. For safe use, you must connect the
ceilometer AC (mains) power supply cable to a grounded mains socket. The communication line
signal ground is also internally connected to the device chassis/safety ground.
