5.6.3.2 Connecting the V
AC
voltage supply – optional
The DIB-500 R4.1 with V
AC
expansion (optional) provides a power supply cable via the
equipment rack for each rectifier module. Rectifier modules are already connected to
the mounting frame and can be connected to the voltage source on site.
With a V
AC
voltage supply (optional), the DIB-500 R4.1 can be connected to the voltage
source on site in the following connection variants:
| to a fixed connection (e. g. distributor box),
with this connection variant, an easily accessible separator must be available in the
voltage supply circuit of the voltage source, such as a fuse in the sub-distribution
| or with a plug with earthing contact to a mains socket.
with this connection variant, the mains socket must be easily accessible and located
as close to the product as possible. The length of the voltage supply cable limits the
possible distance. The length of the voltage supply cable is 2.5 m.
One plug with earthing contact in compliance with CEE 7/VII for each integrated rectifier
module is included in the scope of delivery and already installed upon delivery. The volt-
age supply cable(s) are identified according to the related rectifier module, e.g. "PSU1".
Removing plugs with earthing contact
The plug with earthing contact can be removed when the DIB-500 R4.1 is to be con-
nected to a fixed connection (e.g. distributor box). In this case, the strand ends of the
voltage supply cable/s must be fitted with end sleeves for strands.

Preparation:
The site must be prepared in compliance with the document "Site Requirements".
The equipment rack must be connected to the grounding system.
