3 INSTALLATION
The Power Xpert Meter is designed to be installed, operated and maintained by ad-
equately trained personnel. These instructions do not include all details, variations or
combinations of the equipment, its storage, delivery, installation, checkout, safe operation
or maintenance. Compliance with local, state and national regulations, as well as with
industry standard safety practices for this class of equipment, is imperative.
This chapter describes mounting, wiring, startup and miscellaneous details associated
with the Power Xpert Meter. Every section should be reviewed prior to installing this
device.
WARNING
SHOCK HAZARD:
VERIFY THAT ANY INCOMING AC POWER OR FOREIGN POWER SOURCES ARE
TURNED OFF AND LOCKED OUT BEFORE PERFORMING ANY WORK ON THE
POWER XPERT METER OR ASSOCIATED EQUIPMENT. Failure to do so can result in
death, injury, or damage to equipment.
3.1. Mounting
It is recommended that the Power Xpert Meter is mounted in an electrical switchgear
enclosure that is suitable for its environment. The display and meter modules may be
mounted together or separately. The Power Xpert Meter is designed with flexibility in mind.
While it is recommended that the display be door or panel mounted, the meter can be
mounted remotely from the display on a flat surface or panel elsewhere in the enclosure.
A mounting kit (#PX-PMBA) is available to permit mounting the display and meter modules
together.
•
To maintain proper ventilation, Power Xpert Meter must remain vertical at all times with
3 inches of clearance above and below the chassis. The meter also requires a minimum
of 2 inches of clearance in front of the face plate for wiring clearance or 4 inches of
clearance if fiber optic or RS232 connections are used.
•
The display and meter should be installed in a Pollution Degree II environment.
•
The display MUST be connected to earth ground.
•
The meter should be protected from accidental contact with live terminals in the enclo-
sure. A 1/8 inch steel panel or door, solidly grounded, is recommended.
•
Before cutting the panel, check the required three-dimensional clearances for the
meter case, particularly behind the panel (see the dimension drawings in this chapter).
If mounting on a swinging door, check the swinging clearance of rear projections and
wired connections. Remember to allow for extra space for all wiring, intermediate termi-
nal strips, shorting blocks or any other required components.
•
The Power Xpert Meter comes standard with the remote mounting brackets attached.
•
The display comes standard with the required hardware, five #8-32 x .50 LG Phillips Pan
head SEMS Screws, for mounting the unit to a door or panel.
