7.2 Power, AC

The customer must provide 100-240 Vac power 50/60 Hz to the specified

Location Sensor position. The Location Sensor units require DC 36-57V,

350mA for operation. The power supply used must be ZES approved. The

recommended power supply, which is shipped with the Location Sensor, has a

6 ft (2 m) AC cable and a 6 ft (2 m) dc cable. The electrician should verify

that the AC power is available within 6 ft (2 m) of the position of the Location

Sensor. 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 Location Sensor must always be used with the specified power supply

available from ZES. 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 Location Sensor. 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 ZES account representative concerning limitations or

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

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.
