1. Components are set t ohave center to center distance of 580mm by default 

2. Optional defualt components have center to center distance of 580mm

3. Not part of products, supply along with products, need to be installed by users. Contactors could be fixed on two vertical fitting bars(100-2100Lc) or three vertical bars (2600-3200Lc) or four horizontal fittings bars before final installation, or contactors could be fixed directly on fitting rack withou fitting bars
