INSTALLATION

When Installing this Product...

1. Read these instructions carefully. Failure to follow them could damage the product or cause a hazardous condition.

2. Check the ratings given in the instructions and on the product to make sure the product is suitable for your application.

3. Installer must be a trained, experienced service technician.

4. After installation is complete, check out product operation as provided in these instructions.

CAUTION

Electrical Shock or Equipment Damage Hazard. Can shock individuals or short equipment circuitry.

Disconnect power supply before installation.

Before Installation

IMPORTANT

Expose the photocell to light for 16 hours.

The photocells develop a hysteresis (or “light memory”) when packed for shipping. Until the photocell has been exposed to bright light for at least 16 hours, light level setpoints will shift.

FOR BEST RESULTS, EXPOSE LENS TO LIGHT FROM THE NORTHERN SKY (IN THE NORTHERN HEMISPHERE) OR THE SOUTHERN SKY (IN THE SOUTHERN HEMISPHERE).

USE WATERTIGHT JUNCTION BOX WITH PROPER GASKETS AND SEALS.

Fig. 2. Vertical mounting configuration.

Location

Locate the cadmium sulfide photocell sensor C7057A1000 (supplied with this controller) so that the lens is exposed to full daylight. (See Fig. 2.)

NOTES:

— Select an area which will not become shaded. — Mount only with light entrance facing horizontally. — Avoid overexposure to direct east/west sunlight.

Mounting

IMPORTANT

Mount the photocell sensor to the top of a watertight, outdoor FS junction box.

1. Use the gasket provided to prevent moisture entry.

2. Screw stem into 1/2-14 threaded knockout.

NOTE: The photocell sensor can be mounted in a

7/8 in. hole (or knockout).

Mount the controller on any convenient interior location:

1. Remove the tamper-proof cover.

2. Mount the controller using the two mounting holes

provided in the metal enclosure corners (mounting screws not included).

NOTE: Use controller dimensions in Fig. 1 as a guide.
