4 .2 MPA5500 AC power adaptor
When only one or two MTL5500 modules are required for a particular application, it may be
desirable to power the units from the AC mains supply directly, rather than use a separate DC
supply unit. The MPA5500 is an adaptor that plugs into the DC power socket on the side edge
of an MTL5500 module and clips securely onto the module housing. Its 25V DC power output is
sufficient to supply a single module and can be connected to any normal ac power source.

To fit the adaptor, locate the tongue of the adaptor into the top slot on the side of the MTL5500
module and press the adaptor until it fits closely to the body of the module, as shown.
Use double-insulated AC power cable with conductor parameters of 0.2–1.5mm
2
, or 0.25–
1.5mm
2
if using ferrules. Strip the outer insulation by no more than 30mm, then strip the inner
conductors by 8mm. Insert the cables appropriately in the cage-clamp connectors marked ‘L’
and ‘N’.
The incoming AC power must have some form of power disconnection device, such as a switch
or circuit breaker; a coupler that can be disconnected without the use of a tool; or a separable
plug, without a locking device, to mate with an adjacent socket outlet.
In addition, some form of cable anchorage must be used to relieve the cable conductors from
strain, including twisting, where they connect to the adaptor, and which will also protect the
insulation of the cable from abrasion.
WARNING
This adaptor is not suitable for use with MTL5000

modules.
