Installation - Black Box SP141A Manual

Take the following installation precautions:
1. The protector must be installed directly on
the communication port of the equipment
being protected with no additional
connections between the protector and the
communication port. Any additional
connections or wire length between the
protector and the communication port will
reduce the effectiveness of the protector.
2. A protector will only protect the port to
which it is connected. Other ports on the
equipment will not be protected unless they
too have a protector installed.
3. The green ground wire on each protector
must be securely attached directly to the
chassis ground of the equipment being
protected. Any additional connections or wire
length will reduce the effectiveness of the
protector.
4. The equipment chassis ground must be
connected directly to the building electrical-
safety ground through a proper three-prong
equipment power cord. You can tell whether
the power cord is properly grounded by
measuring for continuity between the metal
chassis and the round prong of the unplugged
power cord using an ohmmeter.
