3030A Weather Resistant Operating Case [CASW] |
| Our weather-resistant operating case provides indoor/outdoor flexibility. |
|
| One of the prime benefits of the 3030A is its small size and portability. But there are occasions when the unit needs to be left unattended for weeks at a time or it needs to be used outdoors or it needs to be securely fastened to a permanent structure to avoid theft. Our weather-resistant operating case [order CASW] provides the solution to these requirements. |

Features of the CASW
|
|
If there is a need to place PolyPower
in permanent mounting or use it in inclement weather,
the CASW is your solution. Your existing PolyPower unit fits
snugly into its die cut foam case and will stay there even when
the case stands erect and the door is open. The cables swing under and
around the unit to exit the case on the right.
Weather-resistance is maintained by compressing high-grade low-memory
foam around them. The sealing is sufficient for all but the most extreme
conditions (such as under water).
Outdoor and rooftop installations often do not have a ready source of 120V power to run the charger for PolyPower. Therefore we have included space for our Line-to-DC accessory [order LDC]. This accessory allows operating PolyPower from the power that is being monitored. If the power being monitored is lost, 3030A's internal rechargeable batteries will bridge over the failure for 8 to 10 hours. This makes the system that more self-contained and able to deal with real-world monitoring problems. Additional cutouts hold the standard charger and a serial communications cable. When the PolyPower unit is locked up in the CASW, communications can be maintained via the serial communications cable that can be run out of the right side of the case. The case has provision for two locks or chains. This can be used for locking the case shut, to eliminate tampering, or to lock it to a permanent fixture to discourage theft. The case is compact (13 x 16 x 7 inches) and comfortable to carry by its handle. It weighs 7 pounds. When combined with our soft accessory case [order SCAS3], it is suitable for transporting your entire system (current probes go in the SCAS3 and sling over the shoulder).
If present, the LDC accessory sits in the provided cutout for it at lower right. The 12VDC outlet and the two red leads are positioned below the bottom layer of foam and end up where the voltage inputs to PolyPower will be. The excess lead length can be positioned underneath the LDC. The LDC in-line fuses should be inserted between the Va and Vb voltage clamps and their associated voltage leads. This puts the fuse protection as close to the source as possible. The 3030A unit is cradled in its designated cutout and the 12VDC plug from the LDC (if present) or the wall charger is plugged into the unit. The voltage leads are routed in through the side and are attached. The Va and Vb leads attach into the stackable leads from the LDC (if present) and then are plugged into the Va and Vb inputs of PolyPower. If working with a single-phase system, then the Va and Vn leads are attached to the LDC leads and then into the Va and Vn inputs of the 3030A. The Ia and In current probes are plugged into PolyPower and then routed under PolyPower to the right side of the case. The Ib and Ic current probes are plugged in and routed to the right. Once all these cables are routed, the unit can be turned on. At this point, monitoring can be started by pressing the buttons of the 3030A or it can be initiated later via the serial cable. Alternatively, if a programmed start time has been programmed into it, nothing more needs to be done. Smooth all the cables out flat on the foam surface at the exit point of the CASW and lower the lid down on them to clamp them in place. Make sure the cables rest only on the compressible foam before closing the case. With the cables securely in place snap the latches shut. You are done. For best results, either leave the CASW standing up or lying down. Do not leave it outside on its side with the handle side on top. If water pools in the depression where the cables exit, seepage can occur over time. |
