3 Features of the NEPTUN chrom
3.1 Ingress Protection 54 (IP54)
The NEPTUN chrom is protected against dust and water according to IP54 regulations.
IP stands for ingress protection and is a rating code commonly used for security
equipment. It consists of two digits, which show the level of protection a device has
against dust and water.
The IP rating normally has two numbers:
➢ First digit: protection from solid objects or materials (dust)
➢ Second digit: protection from liquids (water)
The NEPTUN chrom keyboard has the following rating:
First digit = 5 : Protected against dust (no harmful deposit)
Second digit = 4 : Protection against splashing of water from any directions
Please note: The IP54 rating only applies to the standard version of the NEPTUN

against water and dust:
• Chip card module
• Pointing device
