aution
:
Screw heads or washers reduce voltage clearances. Provide for sufficient clearance to live
conductors (voltage clearance) by using mounting screws with flat screw heads and flat washers. If
mounted on electrically conductive material: The mounting plate has to be earthed and the area un-
der the terminals has to be covered with insulating material.
It is the responsibility of the mounting staff to select the appropriate mounting plate and mounting
screws and to keep the prescribed torque setting.
4.2 Connection
4.2.1 Short-circuit protection
The choice of back-up fuses F should ensure both short-circuit protection for the transformer and the
selectivity to overcurrent devices downstream of the IT systems.
The connecting wires between the automatic transfer switching devices and the overcurrent protective
device downstream are to be laid so that they are short-circuit and earth-fault proof.
When choosing back-up fuses, observe both the maximum permissible values in accordance with the
applicable local regulations and national and international standards to make sure that the contacts are
weld-free.
For recommendations on the use of the appropriate fuse, refer to the nameplate of ATICS® and to the
ordering information in this manual.
