SAFETY INSTRUCTION :-
GENERAL
- The controller must be configured correctly for intended operation. Incorrect configuration could result in damage to the equipment or the process under control.
- The controller is generally part of control panel and in such a case the terminals should not remain accessible to the user after installation.
MECHANICAL
- The Controller in its installed state must not come in close proximity to any corrosive/combustible gases, caustic vapors, oils, steam or any other process by-products.
- The Controller in its installed state should not be exposed to carbon dust, salt air, direct sunlight or radiant heat
- Ambient temperature and relative humidity surrounding the controller must not exceed the maximum specified limit for proper operation of the controller.
ELECTRICAL
- The controller must be wired as per wiring diagram & it must comply with local electrical regulation.
- Circuit breaker or mains s/w with fuse (275V/1A) must be installed between power supply and supply terminals to protect the controller from any possible damage due to high voltage surges of extended duration.
- Circuit breaker and appropriate fuses must be used for driving high voltage loads to protect the controller from any possible damage due to short circuit on loads.
- To minimize pickup of electrical noise, the wiring for low voltage DC and sensor input must be routed away from high current power cables. Where it is impractical to do so, use shielded ground at both ends.
