Installation
The Acq is intended for indoor surface mount applications.
Warning – These installation/servicing instructions are for use by qualified personnel only. To avoid
electrical shock, do not perform any servicing other than that contained in the operating instructions unless you
are qualified to do so.
Always adhere to the following checklist:
Only qualified personnel or licensed electricians should install the Acq meter. The mains
voltages of 120 Vac to 480 Vac can be lethal!
Follow all applicable local and national electrical and safety codes.
Verify that circuit voltages and currents are within the proper range for the meter model.
The line voltage inputs to the meter must be protected by a circuit breakers (not included)
Use 15 or 20A circuit breaker, with separate polls for each voltage phase to be measured.
Disconnect not required for the neutral wire.
Equipment must be disconnected from the HAZARDOUS LIVE voltages before access.
The terminal block screws are not insulated. Do not contact metal tools to the screw terminals if the
circuit is live!
Do not place more than one line voltage wire in a screw terminal or more than one CT wire per screw
terminal.
Before applying power, check that all the wires are securely installed by tugging on each wire.
Do not install the meter where it may be exposed to temperatures below –30°C or above 50°C,
excessive moisture, dust, salt spray, or other contamination. The meter requires an environment no
worse than pollution degree 2 (normally only non-conductive pollution; occasionally, a temporary
conductivity caused by condensation must be expected).
Do not drill mounting holes using the meter as a guide; the drill chuck can damage the screw terminals
and metal shavings can fall into the connectors, causing an arc risk.
If the meter is installed incorrectly, the safety protections may be impaired
Mounting the Device
1)
Begin by identifying the location for mounting the Acq. Ensure the distance from the panel or
load does not exceed the length of the CT’s. The Acq should be mounted in a location close to
the circuit breaker/disconnect switch.
2)
The mounting location should not obscure the vent holes along the side of the product. Provide at least
4 inches of space around all edges of the enclosure to allow for venting and to connect external devices
such as Ethernet LAN, RS485 and USB devices.
3)
Mount the Acqu using six #8 screws, minimum 1” long (not included)
4)
At least three of the mounting screws must be securely attached to a structural wall component such as
a stud. This will ensure adequate support for conduit attachment.
5)
The AcquiSuite is designed to be connected using ¾”conduit. Remove the conduit knockout hole on the
bottom of the enclosure and attach the conduit to the AcquiSuite.
6)
Attach the conduit to the enclosure, make sure the conduit is securely attached and make makes
contact with the ground plate inside the AcquiSuite.
