Installation

2.1 Important notes on using the device

The equipment is designed for operation with Safety Extra-Low Voltage (SELV) by a

Limited Power Source (LPS).

This means that only SELV / LPS complying with IEC 60950-1 / EN 60950-1 / VDE 0805-1

must be connected to the power supply terminals. The power supply unit for the equipment

power supply must comply with NEC Class 2, as described by the National Electrical Code

(r) (ANSI / NFPA 70).

If the equipment is connected to a redundant power supply (two separate power supplies),

both must meet these requirements.

EXPLOSION HAZARD

DO NOT CONNECT OR DISCONNECT EQUIPMENT WHEN A FLAMMABLE OR

COMBUSTIBLE ATMOSPHERE IS PRESENT.

Safety notices when using the device according to ATEX

If you use the device under ATEX conditions you must also keep to the following safety

notices in addition to the general safety notices for protection against explosion:

To comply with EU Directive 94/9 (ATEX95), this enclosure must meet the requirements of

at least IP54 in compliance with EN 60529.

If the cable or conduit entry point exceeds 70 °C or the branching point of conductors

exceeds 80 °C, special precautions must be taken. If the equipment is operated in an air

ambient in excess of 60 ℃, only use cables with admitted maximum operating temperature

of at least 80 ℃.

Take measures to prevent transient voltage surges of more than 40% of the rated voltage.

This is the case if you only operate devices with SELV (safety extra-low voltage).
