8.1 Power, AC

The WhereLAN III location sensor can be powered via IEEE 802.3af POE or

directly with a standalone DC power supply.

If the standalone DC power supply is option is used, the customer must

provide 100-240 VAC 50/60 Hz power to the specified Location Sensor

position. The Location Sensor units require DC 36-57V, 250mA for operation

(12 Watts). The recommended power supply (PS-040-00), which must be

purchased separately, has a 6 ft (2 m) AC cable and a 6 ft (2 m) dc cable. For

longer cabling runs, the recommended power supply is the PS-045-00. The

electrician should verify that the AC power is available within 2 m of the

position of the power supply. The Location Sensor itself may be installed up

to 20 m and 100 m from the PS-040-00 and PS-045-00 power supplies,

respectively. . This allows a 6 ft (2 m) “service loop” margin if the Location

Sensor position must be readjusted after the AC power is installed.

The WhereLAN III must always be used with the specified power supply.

The use of a different power supply could result in equipment damage

and/or electric shock or fire hazard.

Two optional 50 ft (15 m) dc power extension cables are available for

installations in which it is not desirable to rout the AC power within 6 ft (2 m)

of the WhereLAN III. One is for indoor use only and is Plenum Rated, ZES

Part Number PX-010-00. The other is an outdoor rated (UV stable), ZES

Part Number PX-050-00. Consult your ZES Account Manager for

recommended wire size if additional lengths are required for a particular

installation.

Power Supplies have a limited safe operating temperature rating, please

check with the account representative concerning limitations or

availability of extend temperature range power supply, such as PS-040-

00. In outdoor installations the power supply must be installed within a

suitable waterproof housing per applicable building codes. The use of a

non qualified housing could result in equipment damage and/or electric

shock or fire hazard.
