Confirming Correct Installation - Motorola OM 2000 Installation & Operation Manual

3 INSTALLATION
The input of the power supply is isolated from chassis ground. Either the positive or
the negative input terminal can be grounded, as determined by the application. See
the table below for typical –48 V DC system installation:

Red
Black
Green with yellow stripe
CAUTION: This equipment is designed to permit the connection of the earthed
conductor of the dc supply circuit to the earthing conductor at the equipment.
If this connection is made, all of the following conditions must be met:
1 – This equipment shall be connected directly to the dc supply system earthing
electrode conductor or to a bonding jumper from an earthing terminal bar or bus to
which the dc supply system earthing electrode conductor is connected.
2 – This equipment shall be located in the same immediate area (such as adjacent
cabinets) as any other equipment that has a connection between the earthed
conductor of the same dc supply circuit and the earthing conductor, and also the
point of earthing of the dc system. The dc system shall not be earthed elsewhere.
3 – The dc supply source shall be located within the same premises as this
equipment.
4 – Switching or disconnecting devices shall not be in the earthed circuit conductor
between the dc source and the point of connection of the earthing electrode
conductor.

Confirming Correct Installation

After applying power to the OM 2000, there is short initialization period. If the
installation is correct:
•
The green
•
The RF , IF , and FAULT SUMM LEDs may illuminate red to indicate a configuration
error.
When the above sequence is observed, the unit can be configured. Refer to
Section 4, "Setup and Operation"
If the above conditions do not occur, refer to
