Anchoring

Place the controller in the desired installation location. The floor must be flat and level. Use four 12 mm (1/2 in. [M12]) floor mounting bolts to securely fasten the controller to the mounting surface. See Figure 4 the mounting holes in the cabinet.
Refer to Dimension Drawing provided with order documentation for additional details related to cabinet floor plan.
Pre-determined cabinets have been designed for Uniform Building Code (UBC) seismic zone 1, 2A, 2B, 3 and 4, and IBC (International Building Code) seismic activity without overturning or lateral movement, provided they are securely mounted according to UBC, IBC and local building codes. This can include concrete pad design, steel floor design and the sizing of cabinet anchors. Concrete floor cutouts must not be adjacent to floor anchor bolts and must be sized to seismic load. Consult factory if floor mounting must be reviewed by an accredited engineer. Many jurisdictions require an engineer from the local area to review the design. Seismic qualification does not indicate that the equipment will function properly after a seismic event.

NOTES FOR SEISMIC APPLICATIONS
• For installations on concrete – the minimum depth and radius of concrete supporting the cabinet anchors is dependent on seismic loads. Refer to important information above.
• For installations on a metal structure – the metal plate depth and cabinet anchoring method is dependent on seismic loads.

Pre-determined cabinets have been designed for Uniform Building Code (UBC) seismic zone 1, 2A, 2B, 3 and 4, and IBC (International Building Code) seismic activity without overturning or lateral movement, provided they are securely mounted according to UBC, IBC and local building codes. This can include concrete pad design, steel floor design and the sizing of cabinet anchors. Concrete floor cutouts must not be adjacent to floor anchor bolts and must be sized to seismic load. Consult factory if floor mounting must be reviewed by an accredited engineer. Many jurisdictions require an engineer from the local area to review the design. Seismic qualification does not indicate that the equipment will function properly after a seismic event.

Contactor Inspection

See Publication 1502-UM050_-EN-P or 1502-UM052_EN-P for information on pre-energization inspection, vacuum bottle integrity test and insulation resistance test.

Preliminary Checks

Ver if y t he fo llo wi ng :
Contactor current and voltage ratings are correct for the attached load;
Control voltage is correct;
Settings for protective relays;
Heater elements (if provided) in overload relay are secure and undamaged;
Equipment grounding;
External power and control connections match electrical diagrams;
All hardware is correctly reinstalled and torqued to specifications (refer
to Recommended Torque Values
All barriers are replaced to correct positions;
on page 2 of Chapter 1);
34 Rockwell Automation Publication 1512A-UM100F-EN-P - May 2013
Page 43
Common Installation Chapter 4
All fuses are correct class, type and rating;
Mechanical interlocks and isolation switch function properly;
Ensure that any microprocessor-based protection relay is programmed;
Interior of cabinet is free from dirt, loose bolts, tools or metal chips.
Vacuum clean if necessary;
All tools are accounted for. If you cannot locate a tool, do not energize the unit until it is found.

Testing Contactor Operation

1. Connect the appropriate external power supply (120 or 230V AC) to the test receptacle in the control panel. Turn the selector switch to the TEST position.
ATTENTION: Some control circuit configurations may require control jumpers to let the contactor close during the test procedure. Do not jumper any isolation switch contacts such as ISa or ISb (see Figure 61 on
page 60 for the location of these contacts). Using jumpers for these
contacts may result in equipment damage or injury to personnel.
2. Electrically operate the contactor several times. Inspect the armature plate to verify that it fully contacts the magnetic cores.
3. Turn the selector switch to the OFF position and unplug the test voltage.
4. Remove any metal filings or loose hardware from around the magnetic
cores of the vacuum contactor. The debris is attracted to the coil once it is energized and could prevent the contactor from closing properly.

1. Move the isolation switch handle to the OFF (open) position.
2. Loosen the bolt holding the inside cam to the shaft. Do not loosen the bolt
entirely. The cam should not be able to rotate freely on the shaft.
3. Insert a 6.35 mm (0.25 in.) diameter pin into the cam groove between the cam follower and the end of the cam groove.
4. Adjust the cam on the shaft so that the gap from the cam follower to the end of the cam groove is the width of the pin — 6.35 mm (0.25 in.).
5. Tighten the bolt that holds the cam to the shaft. Move the isolation switch handle to the OFF position and recheck the gap using the pin.

IMPORTANT
6. Operate the handle several times, then recheck the 6.35 mm (0.25 in.) clearance between the end of the cam groove and the follower pin for both cams.
7. Verify that auxiliary contact ISb is closed when isolation switch is open. Verify that ISb contact is open when isolation switch is closed.

Adjusting the Change-of-State Point

This procedure sets the secondary electrical interlock. When properly adjusted, the electrical interlock is designed to open the control power circuit before the isolation switch opens as the handle is moved to the OFF position.
1. Once the auxiliaries have been adjusted, move the isolation switch handle to the ON position.
2. Connect a device to indicate continuity across the closed auxiliary contacts.
3. Slowly move the isolation switch handle towards the OFF position and observe the point at which the movable isolation switch blades separate from the incoming line stabs.

Emergency Circumvention Procedure for Power Cell Entry

4. If the auxiliaries do not change state before the isolation switch opens, repeat the auxiliary contacts adjustment procedure (refer to Auxiliary
Contacts Inspection and Replacement on page 58).
ATTENTION: The auxiliary contacts must change state from the closed to open position before the isolation switch blades lose contact with the incoming line stabs. This prevents the isolation switch from being opened while the unit is energized and under load conditions. Failure to correctly set the auxiliary contacts may result in serious damage to the controller and/or injury to personnel.
The interlocking mechanism of the medium voltage starter is designed to prohibit access to the power cell while the isolation switch handle is in the ON position and the isolation switch is closed.
The following procedure is intended to be used only when the isolation switch cannot be opened as described in the Door Opening Procedure for either standard or ArcShield enclosures.
ATT EN TI ON : This procedure may expose personnel to energized medium voltage components. Whenever possible, lock out incoming power before beginning this procedure. If you are unable to lock out incoming power, use the appropriate protective equipment and work practices to avoid shock hazards. Failure to do so may result in severe burns, injury or death.

ArcShield Unit Information
Appendix A

Overview

ArcShield Design

ArcShield units have a robust arc resistant enclosure design that has been tested per IEEE C37.20.7 (2001). Each ArcShield structure was tested to withstand the effects of an arc flash at 40 kA for 0.5 seconds. ArcShield units provide an enhanced Type 2B Accessibility level.
ArcShield units typically include a pressure relief vent on the roof of the structure (some incoming units may not have a pressure relief vent if top cable entry is required). Under arc flash conditions the pressure relief vent will open allowing hazardous flames and gases to exit the enclosure via plenum or chimney system. The low voltage panel area is sealed to prevent flames and gases from entering; however, suitable personal protective equipment (PPE) must be used whenever working on live circuits.
ATT EN TI ON : To ensure Arc resistant integrity, it is important to ensure that the following rules are followed:
The pressure relief vent may not be tampered with, and it is not to be used as a step.
No alterations can be made to the ArcShield structure.
All covers, plates and hardware removed for installation or maintenance
purposes must be re-installed and properly secured. Failure to do so voids the arc resistant integrity.
Power cable entry points are to be treated as the boundary between a hazardous location and sealed accordingly. Failure to do so voids the arc resistant integrity.
A plenum or chimney must be used to direct the arc flash energy to a suitable location. Failure to do so voids the arc resistant integrity. Refer to Appendix B for plenum installation instructions. Refer to Appendix C for chimney installation instructions.
All wiring between the low voltage panel and the power cell must be routed through a suitable gland to ensure flames and gases are not transmitted into this area (as fitted from factory).
The medium voltage power cell doors must be properly secured, using both the handle mechanism and the door bolts (refer to instruction label on the power cell door and Figure 19 on page 17 integrity.
). Failure to do so voids the arc resistance

Appendix A ArcShield Unit Information

Exhaust Systems: Chimney or Plenum Option

Plenum Information

A plenum can be provided for each unit, and is to be field-mounted on the top of the unit structure (some incoming units may not have a plenum if top cable entry is required). The purpose of the plenum is to direct the hazardous flames and gases away from the top of the arc resistant enclosure. Unit plenums are secured to the top of the unit structure and to adjacent plenums, creating a continuous conduit for release of the arc flash energy. Refer to Appendix B installation instructions.
Each plenum based, ArcShield line-up includes a plenum exhaust piece that extends beyond either the left or right ends of the line-up. The other end of the plenums is capped with an end cover. Extensions can be added to the plenum to allow the arc flash energy to be directed further away from the ArcShield line-up to an area where safe venting of the plasma gases can occur.

Plenum Exhaust Considerations

The following options for locating the plenum exhaust are presented:
1. Plenum ducted to an area of the control room where arc gases are permitted to escape, with plenum extensions (see Figure 66
2. Plenum duct to outside of control room (see Figure 66
Plan the location where the plenum will exhaust. Ensure that:
There is no access to personnel while equipment is energized.
Area is free of flammable material or vapors.
Ensure that adequate space is provided around the plenum exhaust, as outlined in
Figure 66
through Figure 68.
Be aware that equipment in the area of the plenum exhaust point will be damaged or destroyed.

Additional Notes

The walls of the plenum exit area must be capable of withstanding the pressure generated.
Any painted surfaces which face direct contact with the arc products may ignite. Flame suppression is recommended.
The exit point can also be outside the building. Ensure exit area can not be blocked by ice, snow, or vermin nests.
Access barriers are recommended as a means of restricting access by personnel while the equipment is energized. Chain link fencing is a suitable barrier material.
Equipment that consists of more than 4 vertical sections bolted together may require additional plenum exits. Rockwell Automation will provide guidance on requirements for additional plenum exits when required.

Chimney Information

Where adequate clean height (space) is available, chimney can be provided for each unit in place of the plenum system. It is to be field mounted on top of the unit structure. The purpose of the chimney is to direct the hazardous flames and gases away from the top of the resistant enclosure. The chimney is secured to the top of each unit structure. Refer to Appendix C instructions.
Each ArcSheild line-up includes a chimney exhaust section that extends vertically directly above the enclosure.
for chimney installation

Chimney Exhaust Considerations

1. From the outlet of the chimney, there needs to be a minimum distance of
1.7 m (67 in.) from the top of the chimney to the ceiling, and 1 m (39 in.) on each side.
2. No obstructions (eg. Piping) can be in the path of the exhaust within this
1.7 m (67 in.) height requirement.
Plan the location where the chimney will exhaust. Ensure that:
There is no access to personnel while equipment is energized.
Area is free of flammable material or vapours.
Ensure that adequate space is provided around the chimney exhaust as

1/4-20 Thread Fasteners – 7.5 N•m (6 lb•ft) 5/16-18 Thread Fasteners – 14 N•m (11 lb•ft)
Bracing of the plenum must be able to withstand the dynamic forces of the arc fault as well as any other vibration or seismic effects associated with the installation. Most of this force will be in the direction opposite to where the relief vent exits. The amount of bracing will depend on how the plenum is supported at its exit as well as the distance from the end of the cabinets to the exit vent.
A flange is available for installing hangers to support the plenum weight.
The plenum extension has holes for mechanical support.
Weight per unit length of Rockwell supplied plenum = 28 kg/m (19 lb/ft).
Installer is responsible for ensuring that the plenum extension has
sufficient support to resist the effect of vibrations and seismic effects.
Plan the location where the plenum will exhaust (refer to Appendix A). Equipment in the area of the plenum exhaust will be damaged or destroyed. Mark the plenum exhaust area as a Hazardous Zone (Figure 69
