III.1 EC housing design
The EC housing models do not have a central plug con-
nection, i.e. the supply and signal cables are fed through
the housing body. (see fig. 3). Consequently, connections
on the camera can be removed easily without need for
disassembling cables; these can be left at the installa-
tion point with the housing rear section and integrated
cables in the event of temporary removal, or used for
connection of another unit in the event of replacement.
We recommend the use of a KV and KVS screw terminal
board for mains distribution and heating connection
(see section VI, Accessories).
