It is the intention of Siemens to update this guide periodically as
new procedures and technologies are developed and employed.
The document is subject to updates without notification.
The scope of this document covers the maintenance interval
schedule to be carried across all the sub-systems of the
VersiCharge Ultra 175kW DC charger system. The sub-systems
include:
• User Unit: The user unit provides an interface for the user (the
electric vehicle driver/owner) and uses the CHAdeMO or
Combo 2 (CCS1) connector to connect one electric vehicle to
the power supply.
• Isolated power unit: The IPU outputs regulated 750 - 950 V DC
to the user unit. It also provides galvanic isolation of the
charging system from the AC grid interface through the
isolation transformer, as well as charge control and
communication to back-office services.
CRITICAL
Except as expressly stated herein, all maintenance must be
performed by a Siemens certified service agent only. In the
absence of a certified service agent, the actions recommended
