Schneider Electric AEM-8120-005, AEM-8120-010, AEM-8240-005, AEM-8240-010 Data Sheet

APPLICATION

The AEM-8120 series and AEM-8240 series transformers are
the only recommended transformers for use with the
CPM-8000 Series Controller, MPC-8000 Series Controller
and the ADM-8304 MPC-8000 Repeater. These transformers
provide low voltage power sources from 50 to 100 Va. Table
1 indicates the number of DLC modules that can be used with
each of the transformers.

INSTALLATION

Caution:

1. Installer must be a qualified, experienced technician.

2. Disconnect power supply before installation to prevent electrical shock and equipment damage.

3. Make all connections in accordance with the job wiring diagram, and in accordance with national and local electrical codes.

4. Do not exceed ratings of the device.

Mounting

Location: This transformer must be mounted on a vibration free

surface. Holes are provided on the base for surface mounting. The
transformer should be mounted in close proximity of the CPM/MPC
Controller or MPC-8000 Repeater (within 10 feet). For dimensions,
See Table 1 and Figure 1.

Wiring

A separate AEM series 24 Vac transformer must be provided for
each CPM-8000 Series Controller, each MPC-8000 Series
Controller and each ADM-8304 MPC-8000 Repeater. The
secondary of each transformer can only be connected to the CPM,
MPC or Repeater that it serves. The supply to the transformer
should be provided with a circuit breaker or disconnect (does not
have to be dedicated). Class 1 wiring must be used for the
transformer wiring. The primary voltages are 120 or 240 Vac.
Secondary voltage is 24 Vac. The enclosed connections are
pigtails for primary wiring, and the screw terminals are for
secondary wiring.

CALIBRATION

Not applicable.
