Installation - GEX75737 Safety Switch User Manual

Mounting

Safety Switches are tested for operation and environmental enclosure ratings in the vertical position, with ON in the up position.

Always check the drawings for required space for each safety switch. The footprint and door swing radius need to be taken into account.

Seismic Certifications

Equipment Installation for Seismic Applications

Introduction

Seismic certification is an optional feature for Safety Switch products and provides seismic conformance options to any of the building codes and seismic design standards identified in the List of Supported Regional Building Codes and Seismic Design Standards. Safety Switches that are seismically certified have been certified to the seismic requirements of the listed code per the manufacturer’s Certificate of Compliance (CoC). Equipment compliance labels and CoC’s are provided with all seismically certified Safety Switches. Refer to the equipment CoC for certification details and applicable seismic parameters. To maintain the validity of this certification, the installation instructions provided in this section must be followed.

Responsibility for Mitigation of Seismic Damage

The Safety Switch equipment is considered a non-structural building component as defined by regional building codes and seismic design standards. Equipment capacity was determined from tri-axial seismic shake-table test results in accordance with the International Code Counsel Evaluation Service (ICC ES) Acceptance Criteria for Seismic Certification by Shake-Table Testing of Nonstructural Components (ICC-ES AC156).

An equipment importance factor, Ip, that is greater than one (Ip > 1.0) is assumed and indicates that equipment functionality is required after a seismic event and after seismic simulation testing. This importance factor is applicable for designated seismic systems (i.e., special certification) servicing critical infrastructure and essential buildings where post-earthquake equipment functionality is a requirement.

Incoming and outgoing bus, cable, and conduit must also be considered as related but independent systems. These distribution systems must be designed and restrained to withstand the forces generated by the seismic event without increasing the load transferred to the equipment. For applications where seismic hazard exists, it is preferred that bus, cable, and conduit enter and exit the bottom of the equipment enclosure.

Seismic certification of nonstructural components and equipment by Schneider Electric is just one link in the total chain of responsibility required to maximize the probability that the equipment will be intact and functional after a seismic event. During a seismic event the equipment must be able to transfer the inertial loads that are created and reacted through the equipment’s force resisting system and anchorage to the load-bearing path of the building structural system or foundation.

Anchorage of equipment (i.e., nonstructural supports and attachments) to the primary building structure or foundation is required to validate seismic conformance. The construction site structural engineer or engineer of record (EOR) or the registered design professional (RDP) is responsible for detailing the equipment anchorage requirements for the given installation. The installer and manufacturers of the anchorage system are responsible for assuring that the mounting requirements are met. Schneider Electric is not responsible for the specification and performance of equipment anchorage systems.

Tie-down Points for Rigid Wall Mounted Equipment

The equipment enclosure provides anchorage tie-down points to accept anchor attachments to the building structure or foundation. Indoor enclosures provide enclosure base frame clearance holes for bolted anchorage attachments, outdoor enclosures provide enclosure base frame clearance holes for bolted anchorage attachments please obtain drawings for actual locations.

Equipment installations of single, stand-alone safety switches must be anchored using all enclosure tie-down points as shown on drawings for indoor and outdoor applications respectively.

Equipment installations using welded supports and attachments in lieu of bolted supports and attachments must ensure the weld locations are distributed similarly to the locations of enclosure anchorage clearance holes. Welded supports and attachments must be properly sized to ensure the weldment withstand capacity exceeds the earthquake demand at location of equipment installation. Precautions shall be made to properly vent and shield the equipment enclosure during the field welding process. Schneider Electric is not responsible for equipment damage caused by field welded supports and attachments.

Anchorage Assembly Instructions

The bolted anchor assembly illustrates the equipment’s as-tested attachment to the seismic shake-table test fixture. The equipment seismic rated capacity, as stated on the Schneider Electric CoC, was achieved with the identified size and grade attachment hardware. Field installed equipment attachment and support detailing shall be in accordance with the anchorage system requirements as defined by the construction site Engineer of Record (EOR) or Registered Design Professional (RDP).

Removal of Knock Outs

Determine the size required.
Remove the smallest knockout first.

Go across from the spot weld and apply force to break the knock out loose. Then crimp the knock out and twist until removed.
Removal of the second knockout full ring.

Two spot welds located across from each other. Go 90° from each spot weld apply force to break each side loose. Then pinch the two sides together and apply rotating force until removed.
Removal of the knock out partial ring.

Go 90° from either spot weld and apply force to break the side loose. The partial side apply force on each partial part of knock out. Pinch the three pieces together and apply rotating force until removed.
Repeat step 3 and 4 until the knock out side requirements are obtained.

Conduit Entry

Drilling into enclosures for creating conduit entry locations may be required. Protect internal components from metal fillings, via drop cloths or orientation of drilling, to prevent foreign materials from contacting electrical connections points. An example of a connection point is lugs, blades, or fuse clips.

Locate conduit entries to comply with bending radius requirements for conductors.

Enclosure Ratings

All Schneider Electric enclosures are certified to UL 50 / CSA C22.2 No. 94.1 and UL 50E / CSA C22.2 No. 94.2 carrying a UL Type Rating. Ratings are equal to or greater than NEMA Ratings of same number.
