USER MANUAL

2.4.

Enclosure Mounting

The WattsOn-MCM is intended to be installed indoors. While the enclosure is rated at NEMA4X, if equipped with the front

panel HMI display, the enclosure is de-rated to NEMA1. Additionally, the enclosure openings must be properly sealed
with rated grommets, glands or covers (not included).

The enclosure is designed for wall mounting using the attached feet. The below diagram shows the dimensions for the
panel mounting feet.

2.5.

Node Installation

Each node can meter up to three independent circuits, and up to 20 can be installed in a single WattsOn-MCM, giving a
total of 60 independent circuits. Each node plugs in to one of the 20 PCI slots on the WattsOn-MCM, numbered 1 through
10 on the left side, and 11 through 20 on the right side. The nodes do not need to be installed in any particular order

–

any node can be installed into any slot, left or right, according to convenience.
