6.4 Power Supply and Protective Ground (Earth) Connections
Power and chassis ground is applied to three screws on a barrier strip on the front of the
Power Supply input module.
Connection of the chassis ground is required (see
Section 2.3)
. There are two chassis ground points that
MUST
be connected to Earth
Ground. One is the Protective Ground (Earth) terminal (terminal 2) on the Power Supply
input, and the other is the mounting flange. Bitronics LLC recommends that all grounding
be performed in accordance with ANSI/IEEE C57.13.3-1983.
6.5 Overcurrent Protection
To maintain the safety features of this product, a 3 Ampere time delay (T) fuse must be
connected in series with the ungrounded/non-earthed (hot) side of the supply input prior to
installation. The fuse must carry a voltage rating appropriate for the power system on
which it is to be used. A 3 Ampere slow blow UL Listed fuse in an appropriate fuse holder
should be used in order to maintain any UL product approval.
6.6 Supply/Mains Disconnect
Equipment shall be provided with a Supply/Mains Disconnect that can be actuated by the
operator and simultaneously open both sides of the mains input line. The Disconnect
should be UL Recognized in order to maintain any UL product approval.
The Disconnect
should be acceptable for the application and adequately rated for the equipment.
