Electrical installation
Cut power to the system!
To prevent unintentional start-up of the system, disconnect the
power during installation of the LCU-P.
The LCU operates with 24 V DC ± 20 % and has a current
consumption of 0.5 A (without load). Connection is potential-
free via two 33-pin plug-in terminal strips. This enables the
wiring to be carried out before the LCU is installed. The
terminals are designed for a max. wire cross-section of:
2
1 x 2.5 mm with sleeve, or
2
1 x 4 mm solid.
The extent of wiring depends on the particular application. The
principle connecting diagram is shown in fig. 5.
