Veris H663 Installation Instructions

WARNINGS

DANGER OF ELECTROCUTION: BE CERTAIN THAT EVERY

CT IS CONNECTED TO A LOAD AT ALL TIMES WHEN CLAMPED TO AN ENERGIZED CONDUCTOR. Current mode Current Transformers (CTs) such as those used in this produc t can be damaged, or generate lethal voltages, if clamped around current carrying conductors while the output leads are not properly terminated to a shorting device, or loaded, as by the H663SM main board. Install wiring connec tors in accordance with manufacturer's speciﬁca-

tions and instructions.

• Potential elec trocution hazard exists. Installing sensors in an energized electrical panel, or on any energized conductor can be ha zardous. CT

outputs should not be connected to Operator Accessible circuits.

• Read instructions thoroughly prior to install

• This product is not intended for life or safety applications.

• This product is not intended for installation in hazardous or classiﬁed locations and must be installed in an electrical and ﬁre enclosure in accordance with EN 61010-1.

Severe injury or death can result from electrical shock during contact with high voltage conductors or related equipment. Disconnect and lock-out all power sources during installation and service. Applications shown are suggested means of installing sensors, but it is the responsibility of the installer to ensure that the installation is safe and in compliance with all national and local codes. Installation should be attempted only by individuals familiar with codes, standards, and proper safety procedures for high-voltage installations.

OPERATION

Designed for the critical load monitoring such as Co-location Data Centers and lighting panels, the H663 series monitors current on up to 42 branch circuits in a 120/208/240 VAC electrical panel. By individually reporting current draw and initiating capacity warnings and alarms, the H663 series allows the user to manage loading and eliminate power disturbances caused by overloaded breakers.

The H663 series consists of a data acquisition system board and up to 42 individual split-core current transformers (CTs). The acquisition board should be mounted inside the electrical panel, or in an enclosure mounted near enough for the CT output leads to reach the acquisition board connectors. The CTs are clipped onto each of the branch circuit conductors. These CTs transmit amperage data from each monitored circuit to the acquisition system for processing.

Current and alarm information is transmitted to the user’s Control Data Acquisition system over an RS485 drop using the Modbus protocol.

Set-up is made easy with a PC based conﬁguration tool which allows for global or individual selection of breaker size, warning levels, and alarm levels.

The H663 Series is a UL508 Listed open device without enclosure.

1 RS 485 2 or 4-Wire Connection

Daisy chain multiple H663's using a 2-wire or 4-wire modbus network. Refer to Figure 4 on page 7.

2 Optical Communications Isolation

Optical isolators are used to separate 120 VAC portions of the circuit from the RS485 network.

3 Alive LED

Flashes once per second to indicate correc t operation. If steadily lit or out, indicates internal failure.

4 Current Transformer (CT) Connectors (Interconnection Boards)

Numbered terminals correspond to the input channels of the acquisition board. Fasten the current transformer connectors into the terminals as shown in ﬁgure 3 on page 3.

5 120 VAC Power Connection*

Easy 2-wire 120 VAC line to neutral 50/60 Hz.

6 250 VAC 100mA Fuse

Fused power connection for circuit protection.

7 Power Transformer

Linear power supply for reliability and low noise

9 Modbus Address Dip Switches

Each Modbus device must have a unique address. These switches must be set to assign an individual address before the device is connected to the network. (See page 5)

10 Lithium Battery

CAUTION! DANGER OF EXPLOSION IF BATTERY IS INCORRECTLY REPLACED. REPLACE ONLY WITH THE SAME OR EQUIVALENT TYPE RECOMMENDED BY THE MANUFACTURER. DISPOSE OF USED BATTERIES ACCORDING TO THE MANUFACTURER'S INSTRUCTIONS.

11 TX LED

Indicates transmission of information over the Modbus network.

12 RX LED

Indicates data received on the Modbus network

13 Current Sensors

Each current sensor is capable of monitoring conductors carrying up to a maximum of 50 amps.*

* The H663SM-42H is capable of monitoring conductors up to a maximum of 100 amps.

8 Baud Rate & Parity Selection Switches

Field selectable RS-485 serial interface control. (See Chart 1 on page 5)

*For 240VAC Power Connection versio n, order catalog number H663SM-xxE.

Physical Installation

1. Snap split-core CT’s on branch circuit wires. (CT’s may need to be staggered).

2. Prepare 120VAC* 50/60Hz power leads and connect to line and neutral terminals of the acquisition board. Allow wiring length to ﬁt when board is installed. DO NOT CONNECT LINE VOLTAGE UNTIL LAST STEP!

3. Connect current transformers to interconnection board terminals as shown in Figure 3.

4. Acquisition Board Installation (see Figure 2) Find screw holes under panel board in side of chassis or panel. Attach Data Acquisition Board.
