4.3.2 Withdrawable unit compartment in
SFD
The vertical distribution busbar is covered test finger
proofed (IP2X). Phase separation is possible. No connection
work is required in the compartment (Fig. 4/8). The internal
separation options up to form 4b lead to a high degree of
personal safety. Connection is effected in a separate cable
connection compartment. The connection data for main
circuits are stated in Tab. 4/9, those for auxiliary circuits in
Tab. 4/10 and the number of available auxiliary contacts in
Tab. 4/11.
