Unit has to be supplied by a power supply specified as a Limited Power Source (LPS) ac-
cording to clause 2.5 of IEC/UL 60950-1 or CEC/NEC Class 2 source of supply as defined
in the Canadian Electrical Code, CSA C22.1 and National Electrical Code, ANSI/NFPA 70. If
the power supply/cable provided with device is not used, always use the cables with minimum
wire size (nominal cross section) 0.5 square mm for power supply.
The power supply for the router must be between +10 V to +60 V DC supply. Protection
against reversed polarity without signaling is built into the router. Note: The protection against
reversed polarity is lost if the negative pole is grounded!
The router can be put into low power mode using a special command lpm. It can then be
awakened, for example, by an activity on binary input or using an internal timer. Consumption
in LPM mode may vary depending on the configuration of the router.
Circuit example:
Note for PoE: See Chapter
impact the power supply usage. The power supply for a PoE PSE router has to meet
other specific requirements.
