2. Loosen and remove the nut securing the sensor connector inside the enclosure. Remove the
sensor connector and wires. Repeat step 1 and 2 for the other sensor connector.
3. After the controller is in place in the panel, reinstall the sensor connectors and reconnect the
wiring to terminal J5 as shown in Figure 19 on page 21.

3.2 Wiring Safety Information
When making any wiring connections to the sc100 Controller, the following warnings and 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 5.
DANGER
Always disconnect power to the instrument when any making electrical connections.
3.2.1 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.
3.3 Electrical Installation
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.

3.3.1 Installation in Conduit
In hard-wired electrical applications, the power and safety ground service drops for the instrument
must be 18 to 12 AWG. See Figure 10 on page 13 for strain relief and conduit opening sealing plug
information. See section 3.3.3 on page 14 for wiring information.
3.3.2 Installation Using a Power Cord
A sealing-type strain relief to maintain the NEMA 4X/IP66 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 on page 39. See Figure 10 on page 13 for strain relief
and conduit opening sealing plug assembly. See section 3.3.3 on page 14 for wiring information.

3.3.3 Wiring for Power at the Controller
DANGER
Explosion hazard. Do not connect or disconnect electrical components or circuits to the
equipment unless power has been switched off or the area is known to be non-hazardous.
DANGER
Do not connect AC power to a sc100 24 V DC powered model.
The sc100 can be purchased as either an 100–230 V AC powered model or a 24 V DC powered
model. Follow the appropriate wiring instructions per the purchased model.
Important Note: A protective earth (PE) ground connection is required by the sc100 for both
100–230 V AC and 24 V DC wiring applications. Failure to connect a good PE ground connection
can result in shock hazards and poor performance due to electromagnetic interferences. ALWAYS
connect a good PE ground to the sc100 terminal.
The controller can be wired for line power by hard-wiring in conduit or wiring to a power cord.
Regardless of the wire used, the connections are made at the same terminals. A local disconnect
designed to meet local electrical code is required and must be identified for all types of installation.
See Figure 13 and Figure 14 on page 16 for suggested local disconnect configurations.
1. Obtain appropriate fittings with NEMA 4X/IP66 environmental rating.
2. Loosen the screws using a phillips-head screwdriver and open the hinged controller cover.
3. Remove the high-voltage barrier (see Figure 9 on page 13).
4. Insert the wires through the strain relief fitting or conduit hub located in the right-rear access
hole in the bottom of the enclosure. Tighten the strain relief if used, to secure the cord.
5. Properly prepare each wire (Figure 11) and insert each wire into the terminal according to
Table 2 or Table 3. Tug gently after each insertion to ensure the connection is secure.
6. Seal any unused openings in the controller box with conduit opening sealing plugs.
7. Reinstall the high-voltage barrier and latch to secure.
