INSTALLATION GUIDELINES

1. Prepare the cut-out with proper dimension as shown in figure.
2. Remove clamp from Controller.
3. Push the Timer through panel cut-out and secure the Controller in its place by tightening the side clamp.

SAFETY INSTRUCTION MECHANICAL

• Ambient temperature and relative humidity surrounding the Controller must not exceed the maximum specified limits..
• The Controller in its installed state must be protected against excessive electrostatic or electromagnetic interferences.

ELECTRICAL

• The Controller must be wired as per wiring diagram & it must comply with local electrical regulation.
• The Electrical noise generated by switching inductive loads might create momentary Fluctuation in display, latch up, data loss or permanent damage to the instrument. To reduce this use snubber circuit across the load.
