# 2 Safety

## 2.1 Introduction

During work with electrical equipment, precautions are necessary to make sure that the safety for personnel and property is sufficient and satisfactory. The safety instructions in the documents that belong to Clear Blue Technologiies Micro system must be followed during installation, testing, commissioning, maintenance, repair and removal of power and supervision of equipment.

Clear Blue Technologies Micro system has been certified in regard to personal safety according to IEC CB Test certificate issued by Intertek. The certificate reference number is SE-06031 and a copy with more information is available on Clear Blue Technologies home page.

<mark style="color:green;">Site owner personal safety regulations are complemented by the information in this document. If the recommendations in this document differ from the site owner regulations, the site owner regulations override this document. Make sure that all personnel involved understand and obey the site owner regulations before starting to work on site.</mark>

## 2.2 Basic Guidelines

{% hint style="warning" %} <mark style="color:orange;">Warning</mark>

<mark style="color:orange;">Do not open, or make modifications to, any Clear Blue Technologies Micro converter unit. This is strictly prohibited and can be a threat to life.</mark>
{% endhint %}

{% hint style="warning" %} <mark style="color:orange;">Warning</mark>

<mark style="color:orange;">All personnel involved must have sufficient competence and training for Clear Blue Technologies Micro Solution installation and maintenance. If not, there is a risk of personal injury and a risk of damage to the equipment.</mark>
{% endhint %}

{% hint style="warning" %} <mark style="color:orange;">Warning</mark>

<mark style="color:orange;">Keep the site clean and clear of redundant material to decrease the risk of accidents.</mark>

<mark style="color:orange;">- Add protection to prevent any electronics in the cabinet from getting wet or moist during work on site.</mark>

<mark style="color:orange;">- Always close the cabinet when the work is complete.</mark>&#x20;

<mark style="color:orange;">- Take note of any labels on auxiliary site equipment that may identify dangers or give other relevant information for work on site. Make sure that all personnel on site are familiar with such information and understand the danger. Do not remove any such labels.</mark>

<mark style="color:orange;">- Only use tools and equipment for their intended purpose.</mark>

## 2.3 High Energy & High Voltage

{% hint style="warning" %} <mark style="color:orange;">Warning</mark>

<mark style="color:orange;">High energy and high voltages of up to 480 V AC are used to power the equipment. High voltage poses a significant risk of electric shock. Batteries can contain large quantities of energy. To touch battery terminals directly or indirectly through cables or moist items can cause discharge of the contained energy. Fast discharge of contained energy can start a fire or cause serious injury or death to workers.</mark>&#x20;

<mark style="color:orange;">- Metal objects such as rings, watches, bracelets, etc. that can cause short circuits in the equipment, must not be worn when working on or around live equipment.</mark>

<mark style="color:orange;">- Make sure that equipment and facilities are correctly grounded to keep the risk of personal injury and equipment damage to a minimum.</mark>

<mark style="color:orange;">- The tools that are used on live equipment must have factory insulation according to IEC 900 standards for hand tools. Tools that have insulating tape as insulation are not permitted.</mark>

<mark style="color:orange;">- The tools that are used must be inspected for damage before each shift. Do not try to repair defective tools on your own.</mark>

<mark style="color:orange;">- Installed cables must be clearly identified with labels.</mark>

<mark style="color:orange;">- All battery cables must have the two ends identified to prevent accidental short circuits.</mark>

<mark style="color:orange;">- Charged cells in a battery have a short circuit effect. A short circuit between the terminals can cause dangerous burns and a spark formation can make the cells burst.</mark>

<mark style="color:orange;">- Keep the working area clean.</mark>

<mark style="color:orange;">- It must be possible to disconnect the load and the AC and DC supplies from the system. The AC disconnection breakers must be installed so that all phases can be switched off in one step. Local rules must be obeyed.</mark>

<mark style="color:orange;">- The unit must be de-energized before work with power related connections above 24 V starts. Note that there can be more than one power source connected to the Micro Modular system and that the filters in an Micro Modular converter unit may be charged even if the supply voltage is disconnected.</mark>

<mark style="color:orange;">- Before the power supply to the equipment is switched on, all tools and other objects not related to operation of the Micro Modular system must be removed.</mark>
