Power Supply

Powering CIPer Model 50

Power is supplied via a removable terminal plug (attached to terminals 1 and 2).
The power supply of the CIPer Model 50 controller must conform to Safety Class II. To reduce overall current
consumption, the CIPer Model 50 can be powered by a switch power supply (rather than by a transformer).
See also Table 2.
NOTE
Due to the risk of short-circuiting (see Figure 24), it is strongly recommended that the CIPer
Model 50 controller be supplied with power from a dedicated transformer. However, if the
CIPer Model 50 controller is to be supplied by the same transformer powering other
controllers or devices (e.g., the PW M-Bus Adapter), care must be taken to ensure that correct
polarity is observed.
