caught in the chassis when you install and maintain the switch.
Electricity safety
• Clear the work area of possible electricity hazards, such as ungrounded power extension cables,
missing safety grounds, and wet floors.
• Locate the emergency power-off switch in the room before installation so you can quickly shut power
off when an electrical accident occurs.
