Installation
CENTRON® Meter Technical Reference Guide 13
The practice of knowingly installing Form 12S/25S meters into
metering sockets with either missing or disconnected fifth terminal
jaws in the meter socket is NOT recommended for CENTRON Form
12S/25S meters.
The following guidance should be followed when using the Form
12S/25S CENTRON meter:

This version of the meter should not be used in a non-Form
12S or 25S metering service.

The meter's 5th terminal should be properly installed on
the meter in a location defined in the CENTRON Technical
Reference Guide.

The fifth terminal jaw in the meter socket should be
properly connected to the service neutral and installed in
the correct location.

The metering service should match the class, form and
voltage rating on the meter's nameplate.
Failure to follow these recommendations will result in damage to the
CENTRON Form 12S/25S meter and void all product warranties.
Programming the C12.19 C1SD,T, L Meter
The personality module should be powered prior to programming. The module can be
programmed using the optical connector. The communications rates through the optical
tower are 9600 baud to 28,800 baud. Refer to PC-PRO+ Advanced documentation for
detailed programming information.
Retrofitting with Personality Modules
CENTRON meters can be upgraded to increase functionality by changing the Personality
Modules.
Do not power ON the meter without the inner cover in place. Power
the meter OFF before removing the inner cover. Personality modules
are sensitive to ESD damage. Take appropriate grounding measures
before retrofitting!
