WARNINGS
Work on the device/system by unqualified personnel or failure to comply with
warnings can result in severe personal injury or serious damage to material.
Only suitably qualified personnel trained in the setup, installation,
commissioning and operation of the product should carry out work on the
device/system.
Only permanently-wired input power connections are allowed. This equipment
must be grounded (IEC 536 Class 1, NEC and other applicable standards).
If a Residual Current-operated protective Device (RCD) is to be used, it must be
an RCD type B. However, if the SINAMICS G110 inverter is connected to a
single-phase grounded-neutral star mains network, an RCD of type A is
permissible.
The mains input, DC and motor terminals, can carry dangerous voltages even if
the inverter is inoperative; wait 5 minutes to allow the unit to discharge after
switching off before carrying out any installation work.
This equipment must not be used as an 'emergency stop mechanism' (see EN
60204, 9.2.5.4)
The minimum size of the earth-bonding conductor must be equal to or greater
than the cross-section of the power supply cables.
Safety regulations must not be compromised when installing inverters!
CAUTION
The connection of power, motor and control cables to the inverter must be carried
out as shown in Figure 2-8 on page 28, to prevent inductive and capacitive
interference from affecting the correct functioning of the inverter.

2.1 General

Installation after a Period of Storage
Following a prolonged period of storage, you must reform the capacitors in the
inverter. It is important that the time of storage is calculated from the time of
manufacture and not the time of delivery. The requirements are shown below.
