consists of one display module and two or more probe modules. Each probe module can
be configured to accept up to 8 sensors each.
Each probe module can also be configured with relays, analog outputs, analog or digital
inputs, and digital field-bus cards.
This symbol, if noted on the instrument, references the instruction manual for operation and/or safety information.
This symbol, when noted on a product enclosure or barrier, indicates that a risk of electrical shock and/or
electrocution exists.

3.3 Wiring Safety Information
DANGER
Always disconnect power to the instrument when making electrical connections.
When making any wiring connections to the sc1000 Controller, 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 Safety Information on
page 7.
Remove the display module before performing any wiring tasks (Figure 6).
Figure 6 Remove Display Module and Probe Module Cover
3.3.1 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 from your body. This can be
accomplished by touching an earth-grounded metal surface such as the chassis of an
instrument, or a metal conduit or pipe.
•To reduce static build-up, avoid excessive movement. Transport static-sensitive
components in anti-static containers or packaging.
•To discharge static electricity from your body and keep it discharged, wear a wrist
strap connected by a wire to earth ground.
•Handle all static-sensitive components in a static-safe area. If possible, use anti-static
floor pads and work bench pads.

3.4 Electrical Installation
DANGER
Only qualified personnel should conduct the installation tasks described in this
section of the manual.
DANGER
Always install a residual current circuit breaker (rccb) with a maximum trigger
current of 30 mA. If installed outside, provide overvoltage protection.
If installed outdoors, provide overvoltage protection between the power and the sc1000
controller system. Make sure the data and power cables do not cause tripping and do not
contain any sharp bends. Refer to Figure 8 for housing breakout information.
High-voltage wiring for the controller is conducted behind the high voltage barrier in the
controller enclosure. The barrier must remain in place unless a qualified installation
technician is installing wiring for power, alarms, or relays. See Figure 9 for barrier removal
information.
The instrument can be wired for line power by hard-wiring in conduit or by wiring to a
power cord if allowed by local electrical code. A local disconnect designed to meet local
electrical code is required and must be identified for all types of installation. See Figure 10
and Figure 11 on page 16 and for suggested local disconnect configurations.
Do not connect the electrical power supply to the AC power until the sc1000 controller
system has been fully wired, fused, and the high voltage barrier and probe module cover
have been replaced.
3.4.1 Installation in Hard-wired Applications
In hard-wired electrical applications, the power and safety ground service drops for the
instrument must be 18 to 12 AWG. A sealing-type strain relief must be used to maintain
the IP65 environmental rating. See Figure 7 on page 14 for strain relief and conduit
opening sealing plug assembly. See Figure 10 on page 16 for wiring information.
3.4.2 Installation Using a Power Cord
A sealing-type strain relief to maintain the IP65 environmental rating and a power cord
less than 3 meters (10 feet) in length with three 18-gauge conductors (including a safety
ground wire) can be used, see Replacement Parts and Accessories on page 57. See
Figure 7 for strain relief and conduit opening sealing plug assembly. See Figure 11 on
page 16 for wiring information.

3.4.3 Wiring for AC Power at the Controller
DANGER
Failure to connect to a good low impedance Protective Earth ground can result in
both a shock hazard and poor performance against electro-magnetic interferences.
1. Obtain appropriate fittings with IP65 environmental rating.
2. Remove the display module from the probe module (Figure 6 on page 13).
3. Remove the four screws securing the probe module front cover. Open the probe
module and disconnect the chassis ground connection from the ground stud to the
cover (Figure 13 on page 18).
4. Remove the six screws from the high voltage barrier and remove the barrier.
5. Insert the wires through the PG1 opening and strain relief fitting or conduit hub.
Tighten the strain relief if used, to secure the cord.
6. Strip the cable outer insulation 260 mm (10 in.). Shorten all wires except the earth
wire 20 mm (0.78 in.), so the earth cable is 20 mm (0.78 in.) longer than the other
cables (Figure 12).
7. Feed the stripped power cable through the ferrite core twice (Figure 12) and wire into
the terminal as shown in Table 5 and Figure 14. Tug gently after each insertion to
ensure the connection is secure.
8. Seal any unused openings in the controller box with conduit opening sealing plugs.
9. Reinstall the high voltage barrier.
10. Reconnect the chassis ground connection to the ground stud of the probe
module cover.
11. Reinstall the probe module cover and screw into place.
