Installation
3.6 Connecting the air purge
Air purge helps control condensation and corrosive vapors within
the sample unit and is recommended. Use dry instrument air only.
See Figure 12 and Figure 13 for installation details.
3.7 Electrical installation
3.7.1 Wiring safety information
When making any wiring connections to the instrument, the
following warnings and notes must be adhered to, as well as, any
warnings and notes found throughout the individual installation
sections. For more safety information refer to section 2.1 on
page 9.
DANGER
Always disconnect power to the sc controller when making
electrical connections.
3.7.1.1 Electrostatic discharge (ESD) considerations
Important Note: To minimize hazards and ESD risks, maintenance
procedures not requiring power to the analyzer should be
performed with power removed.
Delicate internal electronic components can be damaged by static
electricity, resulting in degraded instrument performance or
eventual failure.
The manufacturer recommends taking the following steps to
prevent ESD damage to your instrument:
• Before touching any instrument electronic components (such
as printed circuit cards and the components on them)
discharge static electricity by touching an earth-grounded metal
surface such as the chassis of an instrument or a metal conduit
or pipe.
• To avoid static electricity buildup and to keep it discharged,
wear a wrist strap connected by a wire to earth ground.
• To reduce static build-up, avoid excessive movement.
Transport static-sensitive components in anti-static containers
or packaging.
• Handle all static-sensitive components in a static-safe area.
If possible, use anti-static floor pads and work bench pads.
3.7.2 Connecting/wiring the SS7 sc or SS7 sc-HST to the sc controller
3.7.2.1 Attaching the SS7 sc with a quick-connect fitting
The SS7 sc/SS7 sc-HST cable is supplied with a keyed
quick-connect fitting for easy attachment to the controller
(Figure 14). Retain the connector cap to seal the connector opening
in case the cable must be removed. The original six-foot cable may
be extended by a maximum of 9.6 m (31.2 ft), see Replacement
parts and accessories on page 51.
