ELECTRICAL INSTALLATION (continued)

EN61010 - /CSA 22.2 No 1010.1 92

Compliance shall not be impaired when fitted to the final installation.

Designed to offer a minimum of Basic Insulation only.

The body responsible for the installation is to ensure that supplementary insulation suitable for Installation Category II or III is achieved when fully installed.

To avoid possible hazards, accessible conductive parts of the final installation should be protectively earthed in accordance with EN6010 for Class 1 Equipment.

Output wiring should be within a Protectively Earthed cabinet.

Sensor sheaths should be bonded to protective earth or not be accessible.

MODEL CN9412

TYPICAL CONNECTION DIAGRAM

The SSR driver output is allocated to SP1 and wired to switch the load (heater) using an SSR

F1 Fuse: time lag type to IEC127. CSA/UL rating 250Vac

F2 Fuse: High Rupture Capacity (HRC) Suitable for maximum rated load current

S1 Switch: IEC/CSA/UL Approved disconnecting Device

Comms option (when fitted)

E l e c t r i

Live parts should not be accessible without the use of a tool.

When fitted to the final installation, an IEC/CSA APPROVED disconnecting device should be used to disconnect both LINE and NEUTRAL conductors simultaneously.

A clear instruction shall be provided not to position the equipment so that it is difficult to operate the disconnecting device.
