Precharging intervals of the DC link
SINAMICS Booksize units
The precharging intervals of the DC-link for Line Modules in Booksize format can be calculated using the following
formula

SINAMICS chassis units
For Line Modules in chassis format, the maximum permissible DC link precharging interval is 3 minutes. This applies
irrespective of whether the unit is a SINAMICS G or S type.

Operator Panel
The SINAMICS range includes two operator panels for unit variants S120 (Booksize, Chassis, Cabinet Modules),
S150, G130 and G150. The Basic Operator Panel is designed to meet simpler requirements while the Advanced
Operator Panel offers a wider scope of functions.
Basic Operator Panel (BOP20)
The optional Basic Operator Panel BOP20 that can be plugged into any CU320 Control Unit can be used to
acknowledge faults, set parameters and read diagnostic information (e.g. warnings and error messages).
The Basic Operator Panel BOP20 has a backlit two-line display area and 6 keys.
View of the Basic Operator Panel 20
The integrated plug connector to the rear of the Basic Operator Panel BOP20 supplies its power and enables com-
munication with the CU320 Control Unit. It cannot be sited at a distance from the Control Unit or installed remotely
and connected via a cable.
Advanced Operator Panel (AOP30)
The Advanced Operator Panel AOP30 is a comfortable optional input/output device. In contrast to the BOP20, this
panel offers commissioning and diagnostic functionality in addition to the functions required in normal operation. The
panel features a multi-line graphic display on which a wide range of help functions can be called.
