Procedure 5-1: Switching on and testing the supply voltage
Overview
This section describes the procedure for activating the voltage supply lines via the PI/100
units. Please observe the order of the steps described below.
OTE: If "breaker-less" PIs (PI/100 OCB) are used, the system must be switched on or
off via an external equipment (e.g. Power Distribution Panel (PDP) with circuit breakers).
More information is given in section
Required equipment
Prior to performing this task, the following equipment must be available:
1. Multimeter
2. Small pen or small Phillips screwdriver.
Prerequisites
Prior to performing this task, make sure that the circuit breakers on both PI/100 units are
in the OFF position (="O") (see
Procedure
Proceed as follows to switch on and test the voltage supply lines:
...................................................................................................................................................................................................
1 Insert a 125 A fuse for each supply line into the external Battery Distribution and Fuse
Bay (BDFB). If circuit breakers are being used in the BDFB, put both of them in the O
position.
...................................................................................................................................................................................................
Use a multimeter to check the primary voltage at the Power Distribution Panel (PDP) for
2
both power supply feeders, and enter the measured values in the table provided in chapter
6.
Use the following four pairs (multimeter connection points) for the measurement (see
Figure 4-2, "PDP connection (power input cables)" (p.
1. –A1/rtnA1
2. –B1/rtnB1
3. –A2/rtnA2
4. –B2/rtnB2.
Result:
CAUTIO : Do not proceed if the voltage is outside the range!
