Chapter 2 Power modules Manual VIPA System SLIO
2-2 HB300E - PS-CM - Rev. 11/28
Safety precautions
The Power modules were designed and constructed:
• to be installed on mounting rail along with System SLIO components
• for installation in a cabinet with sufficient ventilation
• for industrial applications
The following precautions apply to applications employing the Sys-
tem SLIO power supplies.
Danger!
• The Power modules must be installed in protected environments that
are only accessible to properly qualified maintenance staff!
• The Power modules are not certified for applications in explosive
environments (EX-zone)!
• You have to disconnect the Power modules from the main power source
before commencing installation or maintenance work, i.e. before you
start to work on a power supply or the supply cable the main supply line
must be disconnected (disconnect plugs, on permanent installations the
respective fuse has to be turned off)!
• Only properly qualified electrical staff is allowed to install, connect
and/or modify electrical equipment!
• To provide a sufficient level of ventilation and cooling to the power
supply components whilst maintaining the compact construction it was
not possible to protect the unit from incorrect handling and a proper
level of fire protection. For this reason the required level of fire
protection must be provided by the environment where the power supply
is installed (e.g. installation in a switchboard that satisfies the fire
protection rules and regulations)!
• Please adhere to the national rules and regulations of the location
and/or country where the units are installed (installation, safety
precautions, EMC ...).
