3 Installation:
These instructions cover the installation, commissioning and maintenance of the Mxp-049, Mxp-050, Mxp-051
and Mxp-549, Mxp-550, Mxp-551 models.
For use of the Mxs-049, Mxs-050 & Mxs-051 in an OEM / customer supplied enclosure, these power supplies
should be mounted in an appropriate sized enclosure suitable for the intended batteries to be used. The
minimum protection rating of the enclosure must be to IP30 and the power supply must be earthed. Take note of
the important safety information in the remainder of this document. An input supply lead with AC Mains Terminal
Block is supplied in the kit.

NB: The batteries must not be mounted in an enclosure separate from the power supply since this could affect
the temperature compensating charging characteristics, resulting in incorrectly charged batteries.
The power supply modules are also incorporated into other boxed peripheral units. The information in this
document is applicable to these power supplies. Refer to the additional data sheet supplied with each boxed
unit for details on the installation, configuration and use of the peripheral function.

EN54-4 requires that when an EN54-2 CIE is housed in a separate cabinet to the EN54-4 PSE, the CIE shall be supplied via at least two
monitored supply (transmission path) circuits such that a short or open circuit in one circuit does not prevent supply of power to the CIE.

Advanced Electronics Ltd does not warrant that the equipment continues to satisfy the requirements for compliance with the EMC
Emissions Directive, Low Voltage Directive or EN54-
4 when caged units are mounted in a customer’s own enclosure. Ensure continued
compliance through appropriate testing and/or notified body certification.
