Power connection X12
Please consider the following aspects:
Voltage balancing:
on installing several ELCs the ballasts have to be equally distributed on
all phases
(e.g. 1
st
ballast L1/L2, 2
nd
ballast L2/L3, 3
rd
ballast L3/L1 etc.).
Cut-Out and loop impedance
: The installation of an automatic cut-out is required for line
protection. It is necessary to check the loop impedance afterwards.
Using an RCD:
if an RCD is required we recommend an RCD type B. When using a RCD
consider the leakage current given in chapter 6.
Shielding:
The lamp feeder cable shielding must be connected to the ELC at the designated
shield clamp, see chapter 3.2.9.
If desired, the shielding can also be connected to the lamp unit.
