Follow these instructions when connecting the DC switch variant. Read “Safety” on page 23 of this document before connecting a DC power supply.

Warning Only trained and qualified personnel should connect a DC power supply.

For centralised DC power connection, the switch should be installed in restricted access areas only (such as dedicated equipment rooms or equipment closets) in accordance with Articles 110-16, 110-17, and 110-18 of the National Electrical Code, ANSI/NFPA 70.

Damage to equipment may result if power is connected improperly.

Before working on equipment that is connected to power, remove jewellery including rings, necklaces, and watches. Metal objects will heat up when connected between power and ground, and can cause serious burns or weld the metal object to the terminals.

NEBS preparation when rack-mounted

To ensure rack-mounted installations are earthed for compatibility with NEBS, all bare conductors must be coated with an appropriate antioxidant compound before making crimp connections.
