Safety Admonishments Definitions
Definitions of the safety admonishments used in this document are listed under “Admonishments Used in this Document” on page v.
You Must Follow Approved Safety Procedures
DANGER!
Performing the following procedures may expose you to hazards. These procedures should be performed by
qualified technicians familiar with the hazards associated with this type of equipment. These hazards may include shock,
energy, and/or burns. To avoid these hazards:
a)
The tasks should be performed in the order indicated.
b)
Remove watches, rings, and other metal objects.
c)
Prior to contacting any uninsulated surface or termination, use a voltmeter to verify that no voltage or the expected
voltage is present. Check for voltage with both AC and DC voltmeters prior to making contact.
d)
Wear eye protection.
e)
Use certified and well maintained insulated tools. Use double insulated tools appropriately rated for the work to be
performed.
DC Input/Output Voltages
DANGER!
This system has a DC source connected to it and provides DC distribution. Although the DC voltage is not
hazardously high, the DC source can deliver large amounts of current. Exercise extreme caution not to inadvertently contact
or have any tool inadvertently contact an input or output terminal or exposed wire connected to an input or output terminal.
NEVER allow a metal object, such as a tool, to contact more than one termination at a time, or to simultaneously contact a
termination and a grounded object. Even a momentary short circuit can cause sparking, explosion, and injury.
DANGER!
Follow local lockout/tagout procedures to ensure DC branch circuit protection devices remain de-energized
during installation at loads, as required.
Buried Utilities
CAUTION!
When installing the enclosure, ensure the site is free of any buried utilities. Call 811 before installation. Severe
damage, serious injury, or death can occur if buried utilities are not identified prior to installation.
Personal Protective Equipment (PPE)
DANGER!
ARC FLASH AND SHOCK HAZARD.
Appropriate PPE and tools required when working on this equipment. An appropriate flash protection boundary analysis
should be done to determine the “hazard/risk” category, and to select proper PPE.
Only authorized and properly trained personnel should be allowed to install, inspect, operate, or maintain the equipment.
Do not work on LIVE parts. If required to work or operate live parts, obtain appropriate Energized Work Permits as required
by the local authority, per NFPA 70E “Standard for Electrical Safety in the Workplace”.
