3.4 Connecting and commissioning
Open equipment
The devices are "open equipment" acc. to the standard IEC 61010-2-201 or UL 61010-2-201
/ CSA C22.2 No. 61010-2-201. To fulfill requirements for safe operation with regard to
mechanical stability, flame retardation, stability, and protection against contact, the
following alternative types of installation are specified:
• Installation in a suitable cabinet.
• Installation in a suitable enclosure.
• Installation in a suitably equipped, enclosed control room.
Power supply
The device is designed for operation with a directly connectable safety extra low voltage
(SELV) from a limited power source (LPS).
The power supply therefore needs to meet at least one of the following conditions:
• Only safety extra low voltage (SELV) with limited power source (LPS) complying with IEC
If the equipment is connected to a redundant power supply (two separate power supplies),
both must meet these requirements.
Connector

Prior to installation, connecting up and commissioning, read the relevant sections in the
system manual "S7-1500 Automation System", see Documentation (Page 9), Documentation
