Power connections

1 Customer access cover
DANGER
Electrocution hazard. Only qualified personnel should conduct the tasks described
in this section of the manual. Connect equipment in accordance with national,
state and local electrical codes.
Power connections are made at the terminal strip located in the left side of the electrical
compartment and are accessible when the customer access cover is opened. Refer to
Figure 9 and Figure 12.
For process or industrial applications, the national electrical codes of most countries
require that AC service feeds be hard-wired and contained in conduit systems. The CL17
Chlorine Analyzer has been designed to conform to this requirement.
Figure 9 Locating and removing customer access cover
Conduit is recommended for two reasons:
1. It is generally required by most local electrical codes.
2. Use of metal conduit can improve immunity to lightning surges and
AC power transients.
2 Use a torx-driver to remove the two screws that hold the
Customer Access Cover in place. Set cover aside.
