INSTALLATION AND MOUNTING

3. For ALL models installation must always comply with
applicable codes, standards, laws and regulations. Adhere
strictly to local, state and national electrical and building
codes. Comply with regulations the Occupational Safety
and Health Administration (OSHA) has established. Also,
the generator and related components must be installed
completely in conformance with the manufacturer's instruc-
tions and recommendations. Following proper installation,
do nothing that might alter a safe installation and render the
unit in non-compliance with such codes, standards, laws and
regulations.
4. The plastic knockout that is used to route the wires and
cables into the annunciator should be removed with the
annunciator firmly supported by placing it on a flat surface.
5. Wire tie-downs are provided in two places on the base of the
annunciator to provide strain-relief for the connecting cables
and wires (Figure 3).
