Safety Precautions, Continued
Local power Source
 AC:
 Safety requirements require a single pole circuit-breaker to be employed
between the local AC power source and power injector.
 The circuit breaker
(1)
must disconnect the mains phase of the AC power
source.
If the plug of power supply cord is intended to be the power
disconnect device of the equipment (not recommended), arrange in
the installation to connect the equipment to a socket-outlet installed
close to the power injector and easily accessible.
 DC:
 Safety requirements require a single pole circuit-breaker
(2)
to be employed
between the local DC power source and power injector.
 The positive (+) V pole of the local DC power source must be grounded.
 The circuit breaker must control (open / close) the negative (-) V pole of
the DC power source.
Power Supply Cable
 AC:
 Power source cables must be tested for short circuits, open circuit or
wrong wiring before installed.
 The ground wire of the AC cable must be connected to the protective
earth (ground) point of the mains electricity installation.
 DC:
 Power source cables must be tested for short circuits, open circuit or
wrong wiring before installed
 The positive wire of the DC cable must be connected to the protective
earth (ground) point of the mains electricity installation (see picture
above).
