5.2 Assembly/Disassembly Opening
Opening the Meter
Your meter is fully assembled, but not wired. See Section 7 for wiring connection for power and sensor inputs. In
most cases, if you have ordered optional boards with the meter, these boards will already be installed.
You will need to remove only the rear cover to complete wiring, but you will have to open the meter to do one or
more of the following:
WARNING! You must disconnect and turn off the power and connector signals before accessing the unit and
installing optional boards. Failure to do so may result in injury!
a. Check or reconfigure the transformer jumpers on the main board so that they correspond to your line voltage
(W1 and W2 for t115 V ac, or W3 for 230 V ac). See Section 5.2.2
b. Install optional boards.
c. Access jumpers on the main and optional boards. See Section 5.2.4
Figure 5-1. Meter Exploded View
Using Figures 5-1 as a guide, follow these simple instructions to open the meter:
IMPORTANT! Turn off the power and input signals from the unit before proceeding. Failure to do so may result in
injury!
1. Remove the cover mounting screw that secures the rear protective cover to the meter, and remove the rear
protective cover. If you are simply wiring the meter – but not checking jumpers or installing or removing boards
– this is as far as the meter needs to be disassembled. Go to Section 5.2.1.
2. Remove all wiring connectors from the rear of the meter.
3. Remove the two thumbnuts that secure the case to the sleeve.
4. Remove the sleeve completely by sliding it back form the front bezel.
5. Using Figure 5-2 as a guide, bend the side-panel detents on the case outward and pull the board assembly out
of the case by the mounting screw stem.
NOTE: From this point forward, these 5 steps are referred to as “Reveal the main board”.
