2.3.4 Electrical power equipment for
−48 V DC (redundant power models
(AX3630S and AX3640S))
(1) DC power cable
The redundant power models contain no accessory power cables. Use the power cable
specified below to connect the Switch to
−48 V DC.

DC power cable 2 16 8 to 10 mm
A trained engineer or maintenance staff should attach and detach the DC power
cable. The terminals of DC power cable are to be connected. Wrong handling of the
DC power cable can cause a fire or an electric shock.
Prior to connecting or disconnecting the DC power cable, turn off the circuit breaker
of the electrical power equipment. Otherwise, an electric shock might result.
Peel the DC power cable jackets (on the Switch side) to 8 to 10 mm.
Too short a sheath length might result in poor contact or a disconnected cable. On
the contrary, too long a sheath length might expose the core wire and cause an
electric shock.
(2) Ground cable
Make sure to use the ground cable supplied with the device.
A cable is shipped whose terminal for the electrical power equipment is unprocessed. The
specifications of the cable for the electrical power equipment are shown in
Table 2-4
General installation conditions for AX3640S series switches (AC models) . Fit the cable
end properly with terminals or by some other means to connect to your electrical power
equipment.
