Installation Personnel
Installation and maintenance of the communications enclosure should
only be performed by qualified, competent personnel who have
appropriate training and experience with high voltage and current
devices. The communications enclosure must be installed in accordance
with all Local and National Electrical Safety Codes.
WARNING
Failure to observe the following may result in severe injury or death:
•Keep these instructions.
•There are no user serviceable parts inside. Refer service
to an authorized service person.
•During normal operation of this device, hazardous voltages
are present on the input terminals of the devices and
throughout the connected power lines. With their primary
circuit energized, current transformers (CTs) may generate
high voltage when their secondary windings are open.
Follow standard safety precautions while performing any
installation or service work (i.e. remove line/ PT fuses,
short CT secondaries, etc.).

•This product must be used in accordance with the
instructions in this manual, otherwise the product may not
perform as expected or cause hazards to the user.
AVERTISSEMENT
Le manque d'observer le suivant peut avoir comme conséquence des
dommages ou la mort graves:
•Il n'y a aucune pièce utile d'utilisateur à l'intérieur, se
réfèrent le service à une personne autorisée de service.
•Pendant le fonctionnement normal de ce dispositif, les
tensions dangereuses sont présentes sur les bandes
terminales d'entrée du dispositif et dans toutes les lignes
électriques reliées. Leur circuit primaire étant activé, les
transformateurs de courant (CTs) peuvent produire de la
tension quand leurs enroulements secondaires sont
ouverts. Suivez les mesures de sécurité standard tout en
effectuant n'importe quelle installation ou travail de service
(c.-à-d. enlevez la ligne fusibles de pinte, secondaries
courts de CT, etc.).
•Gardez ces instructions.
•Ce produit doit être employé selon les instructions en ce
manuel, autrement le produit peut exécuter comme prévu
ou ne pas causer des risques à l'utilisateur.

Danger
Line voltages up to 600 VRMS are present on the
input terminals of the device and throughout the
connected line circuits during normal operation.
These voltages may cause severe injury or death.
Installation and servicing should be performed only
by qualified, properly trained personnel. This is a Class III measurement
device.
Danger
Tensions secteur jusqu'à 600 VRMS sont présent sur
les bornes d'entrée du dispositif et dans toute la
ligne reliée circuits pendant l'opération normale.
Ces tensions peuvent causer des dommages ou la
mort graves. L'installation et l'entretien devraient
être assurés seulement par le personnel qualifié et
correctement qualifié. C'est un dispositif de mesure
de la classe III.

PLCS 600 Installation Guide
Mounting the Enclosure
Location
•The unit should be placed in a secure location, away from
any potential tampering.
•Mount to an indoor or outdoor wall using four M8 or 5/16”
bolts through the holes in the mounting flanges.
•Allow space beneath the
enclosure for conduit runs for all
input and output wires.
•Allow sufficient working space in front of and beside the
unit to allow the front door to open fully.
Distance Limitations
•Maximum 100m (328 feet) from an internet connected
network port if not using an internal cellular modem.
•No further than 2m (6 feet) from earth ground.
•Maximum 1200m (4,000 feet) between communications
enclosure and last RS-485 device
Enclosure Penetrations
•All conduits and wires must enter from the bottom of the
enclosure. Do not penetrate the top or sides of the
enclosure.
9

PLCS 600 Installation Guide
•All entry points must be sealed using weatherproof
connecters.
•Warranty will be voided if there are entry points on the top
or sides of the enclosure.
•All penetrations must be liquid tight. Use outdoor rated
conduit connections for all outdoor installation.
•AlsoEnergy provides a desiccant packet within all
enclosures to reduce the internal humidity of the enclosure.
Replace the desiccant packet when the humidity indicator
card shows 40% relative humidity or higher.
•AC power, voltage reference, and current transformer wire
must not be run through conduit carrying RS485, CAT5e,
or analog sensor wires. Penetrate the enclosure for the two
separate conduits as shown.

Wiring to External Connections
Control Power
•The power supply in the AlsoEnergy PLCS 600 requires
100-277VAC at 0.2A-0.4A, 50-60 Hz, and is auto-ranging.
A neutral wire is required for power, do not use two “hot”
phases to power the enclosure.
•The monitoring system should be protected by a main
circuit breaker rated up to 20 amps.
•Power may be provided from a dedicated circuit. Providing
power from the line side of the voltage reference is not
permitted in all areas. Consult NEC and local regulations if
not powering the enclosure from a dedicated breaker.
Check that power is off at the main breaker and that the
breaker inside the PLCS 600 is off before starting any work.
Complete all other enclosure connections before
energizing the enclosure.
Connect the AC input power with 12-14AWG as
follows.
(1) Circuit Breaker - AC line 100-277VAC
(black)
(2) Terminal Block –AC neutral (white)
(3) Green/Yellow Terminal Block –EGC
(green, green/yellow, or bare copper)
