Note
This warning only applies to DC input sources and is not applicable if an AC power source is used.
The 1552 access point for hazardous locations can be connected to more than one power source. The
access point detects the available power sources and switches to the preferred power source using the
following priority:
1.
AC power or 24 VDC, either but not both at the same time.
2.
12 VDC (not supported in hazardous locations environments)
3.
Power over Ethernet (1552H only)
Warning
This unit might have more than one power supply connection. All connections must be removed to
de-energize the unit.
Statement 1028
Caution
To provide inline PoE, you must use the 1500 power injector (AIR-PWRINJ1500-2=). Other power
injectors, PoE switches, and 802.3af/at power sources cannot provide adequate power, which can cause
the access point to malfunction and cause over-current conditions at the power source.
Caution
The 1500 power injector (AIR-PWRINJ1500-2=) must be used in an indoor environment only, and is not
certified for installation within hazardous locations environments.
