2 Safety

2.1 Safety 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 belonging to the eSite x10 must be followed during installation, testing, commissioning, maintenance, repair and removal of power and supervision of equipment.

Read

Local regulations are complemented by the information in this document. If the information in this document does not agree with the local regulations, the local regulation overrides this document. Make sure that all involved personnel understand the local regulations.

2.2 Basic guidelines

Warning

Alert the site operations manager or other responsible local personnel before work is started on the site.
Inform all personnel near the site that work is in progress and that there is live electrical equipment.
If possible, close off the area until the work is done.
Do not work alone with eSite x10.
Do not leave live electrical equipment with exposed parts unattended.
Keep the working area clean and clear of redundant material to decrease the risk of accidents.
Add protection to prevent water from entering the Connection Compartment during work.
Take note of any labels on equipment that identify potential hazards or give information relevant to the ongoing work. Make sure that all personnel on site are familiar with such information.
Do not remove any labels that identify hazards or give information about equipment on site.
Only use tools and equipment for their intended purpose.
Always use protective gloves and clothing with insulation when drilling.
Always use protective goggles when drilling to protect the eyes from metal fragments and dust.
Do not drill in power equipment; the drill must not touch live wires.
Always close the Connection Compartment lid when the work is complete.
Alert the site operations manager or other responsible local personnel when the work is finished.

2.3 High energy and high voltage

Warning

High energy and high voltages of up to 480V AC are used to power the equipment. High voltage poses a significant risk of electric shock.
Batteries may contain large quantities of energy. Touching battery terminals directly or indirectly through cables or moist items can cause discharge of the contained energy. Fast discharge of contained energy may start a fire or cause serious injury or death.
Metal objects such as rings, watches, bracelets, etc. must not be worn during work with live equipment, as they may cause short circuits in the equipment.
Make sure that equipment and facilities are correctly grounded to keep the risk of personal injury and equipment damage to a minimum.
Tools used on live equipment must have factory insulation according to IEC 900 standards for hand tools. Tools with insulating tape as insulation are not permitted. The tools must be inspected for damage before each shift. Do not try to repair defective tools on site.
Install power cables as instructed.
Installed cables must be clearly identified with labels.
All battery cables must have the two ends identified to prevent accidental short circuits.
Charged cells in a battery have a hazardous short circuit effect. A short circuit between the terminals may cause dangerous burns/spark formation/bursting cells etc.
Smoking, handling combustible compounds or naked flames near the eSite x10 is strictly prohibited. Batteries exposed to flames pose a serious explosion risk.
Put an insulation cover on the battery terminals before working in the battery cabinet with the battery bank installed.
It must be possible to safely disconnect the load, the AC and/or DC supplies from the system. AC breakers must be installed so that all phases can be disengaged simultaneously. Local rules must be obeyed.
The eSite x10 must be de-energized before work with power connections above 24 V is started. Switch all power sources off. Note that there may be more than one power source connected to the eSite x10 and that filter components in the unit may be charged even if the supply voltage is disconnected.
Before the power supply to the equipment is switched on, all tools and other objects not related to the eSite x10 must be removed.
Do not work with electrical installations or near towers during thunderstorms or other hazardous weather conditions.
