Introduction

Do not perform any procedure in this Special Instruction until you have read the information and you understand the information.

This document provides a list of retaining clips compatible and approved for use with all CAT PVT 110 and PVT 110 ARC Modules. This list does not provide recommendations or make evaluations on the final system design or loading requirements. Absence from the list does not indicate that the retaining clip is incompatible, only that the retaining clip has not been submitted to CAT for testing and approval.

CAT warrants its CAT-PVT 110 and 110 ARC modules according to the CAT Module Warranty Terms & Conditions (CAT PD-5-102, "Module Warranty Terms & Conditions") provided modules are installed, operated and serviced as described in the CAT User Guide (CAT PD-5-200, "User Guide") and in the System Design and Application document (CAT PD-2-303, "SDA").

CAT requires all system designs to be submitted for review and approval via the SDA process; therefore, for warranty purposes, every system with CAT modules must be covered by an SDA. Project Developers and/or Customers should request this document from CAT and obtain approval prior to equipment procurement and installation.

Approval of the following listed retaining clips is based upon and in accordance with the drawings and specifications effective at the time of evaluation. Thus, changes in design specifications or fabricator after CAT approval may nullify the confirmation of compatibility. CAT reserves the right to change the approval requirements for the retaining clip as well as a possible revocation of the retaining clip approval list.

Safety Section

Cleaning activities create risk of damage to the modules and array components, as well as the potential for electric shock

Only properly trained personnel who understand the risks of applying water to electrical components should clean modules. Trained personnel shall wear appropriate electrically insulating Personal Protective Equipment (PPE) during cleaning, inspection operations, or when working near modules.

Professional cleaning services trained to work on live electrical systems are available for hire.

The module encapsulating material and glass provide protection from electrical shock hazard when intact. However, when cracked or chipped, the module’s integrity is compromised (i.e., potential loss of electrical insulating properties,) thereby creating an electrical shock hazard.

Note: Cracked or broken modules represent a shock hazard due to leakage currents, and the risk of shock is increased when modules are wet. Before cleaning, thoroughly inspect modules for cracks, damage, and loose connections.

Note: The voltage and current present in an array during daylight hours are sufficient to cause a lethal electrical shock.

Acceptable module cleaning methods include spraying the modules with low-pressure water that is closely matched in temperature to the temperature of the module or to use a dry brushing technique. The following guidelines minimize impact to plant power generation, reduce safety hazards, and minimize risk of module damage.

Show/hide table

Contact with loose connectors can result in electrical shock and may cause injury or death.

Show/hide table

Do not operate or work on this product unless you have read and understood the instruction and warnings in the relevant Operation and Maintenance Manuals and relevant service literature. Failure to follow the instructions or heed the warnings could result in injury or death. Proper care is your responsibility.

Show/hide table

Before servicing/performing maintenance on the machine, electrical power must be physically disconnected; battery plugs must be disconnected from the batteries, or the trailing cable must be unplugged, and warning tags and padlocks shall be applied by a certified electrician. Certified electricians shall perform or direct any electrical work, including any energized testing, repair work in controllers, motors, or other approved compartments, and shall insure that all compartments are properly closed and inspected prior to re-energization. All applicable lock out and tag out procedures must be followed.
