Installation
3.2 Wiring Safety Information
When making any wiring connections to the sc60 Controller, the following warnings must be adhered to, including 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 an d ESD risks, maintenance procedures that donot require 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:
3.3 Electrical Installation
• 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 done 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.
DANGER 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 the wiring for power, alarms, or relays. See Figure 9 on page 13 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 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
DANGER Use of a power cord is not acceptable in Class 1, Division 2 Hazardous Location Installation (see).
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 and Accessories on
page 41. See Figure 10 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-hazard ous.
DANGER Do not connect AC power to a sc60 24 VDC powered model.
The sc60 can be purchased as either an 100–230 VAC powered model or a 24 VDC powered model. Follow the appropriate wiring instructions as per the purchased model.
Important Note: A protective earth (PE) ground connection is required by the sc60 for both 100–230 VAC and 24 VDC wiring applications. Failure to connect a good PE ground connection can result in shock hazards and poor performance due to electromagnetic interferences. AL WAYS connect a good PE ground to the sc60 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 13and Figure 14 on
page 17 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: on page 15. 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.
