INSTALLATION, DIMENSIONS & CONNECTIONS

FOR OPTIMUM PERFORMANCE AND HEAT DISSIPATION, THE UNIT SHOULD BE

MOUNTED VERTICALLY.

(EARTH BONDING DO NOT REMOVE)

WARNING: SWITCH OFF MAINS SUPPLY

BEFORE COMMENCING ANY SERVICING WORK

COOLING REQUIRIMENTS

Heatsink rating for standard stack assembly is calculated when naturally cooled. If mounted in an enclosure or Cabinet, adequate ventilation and/or

forced cooling should be fitted. When thermal trips are fitted we recommend that they are wired in line with the signal to switch off the thyristors in

an over-temperature situation.

Unusual heating loads such as Molybdenum, Platinum or Tungsten, typically have a 10 to 1 hot to cold resistance ratio and therefore, when cold,

draw larger currents than normal. Transformers and other inductive loads have surge starting currents and require the correct type of phase angle

firing circuit. These and similar types of surge loads should be indicated, so that appropriate slow start or larger rated units can be correctly supplied

for the specific needs.

Note: The unit is factory set for manual control or 0-5Vdc. For 0-20mA, a 270R resistor will be required to be fitted across the ‘+ve’ & ‘0v’ terminals

and the zero & span adjusters will need recalibrating.

RECOMMENDATIONS

FUSING

The unit requires an SCR-Type (or FF-Type), fast-acting fuse. On initial ‘switch’ on, some loads may need an increased Factor of Safety (F of S) for

Unit and/or Device protection. See the SRA Data sheet for further information.

CE Marking

This product family carries a “CE marking”. The EVR Series (1kW, 4kW and 6kW) phase angle controller requires a suitable remote filter. For

information, see the recommendation section and contact our sales desk. (See product Declaration of Conformity).
