Figure 5-2. Board Assembly Removing/Installing Detail
The meter is now disassembled to the point where you can check and configure jumpers and install boards.
Reinserting the Main Board Assembly into the Case
Reinsert the main board into the case once jumper s and optional boards have been configured and installed.
Spread the side-panel detents of the case and carefully slide the main board all the way in.
5.2.1 Safety Precaution/Product Id Label
To look at the Rating/Product ID label on the case, you must follow the first step as described in Section 5-2. Refer
to Figure 5-2 for the location of the Product Identification Label.
The meter is protected in accordance with Class I of EN61010. Refer to Safety Considerations page.
WARNING! If your meter is to be wired to sensors to control inputs that could be hazardous potentials, these
potentials will be carried to the 20-pin output connector (P2) at the rear. They will also be present on the meter’s
circuit boards. Follow all instructions carefully BEFORE connecting the meter to any source of power.
DO NOT contact any exposed metal parts, install options board(s), change jumpers, or in any way disassemble or
assemble the meter while it is connected to AC voltage.
Note the following information and guidelines for safe operation of your meter.
Power Voltage
Your power source voltage rating should agree with the voltage under which the meter has been configured to
operate. The first thing you should do is verify this.
The meter’s operating voltage is shown in VOLTS: entry of the Product Identification and Serial Number label. It is
located on the case as shown in Figure 5-2, and is clearly visible on the meter packing box.
5.2.2 Main Board Power Jumpers
To check voltage jumpers or to change from 115 V ac to 230 V ac:
CAUTION! The meter has no power-on switch. It will be in operation as soon as you apply power. To change the
factory presser jumper, disconnect the power from the init. Failure to do so may result in injury. The jumpers must
be changed by specifically trained personnel.
1. “Reveal the Main Board” (refer to Section 5.2, Disassembly).
2. Locate the main board assembly and position it in front of you the same way as shown in Figure 5-3.
3. On the main board, locate the transformer jumpers W1, W2, and W3 near the transformer T1. If your power
requirement is 115 V ac, jumpers W1 and W2 should be installed. (DO NOT INSTALL W3). If your power
requirement is 230 V ac, jumper W3 should be installed. (DO NOT INSTALL W1 OR W2)
