WARNING

• The recorder is not fitted with a switch therefore a

disconnecting device such as a switch or circuit

breaker conforming to local safety standards must

be fitted to the final installation. It must be fitted

in close proximity to the recorder, within easy

reach of the Operator and marked clearly as the

disconnection device for the recorder. A fuse must

be fitted in accordance with Figure 4.

• Remove all power from supply, relay and any

powered control circuits and high common mode

voltages before accessing or making any

connections.

• Use cable appropriate for the load currents: 3-core

cable rated 3 A and 90 °C (194 °F) minimum, that

conform to either IEC 60227 or IEC 60245. The

terminals accept cables from 0.8 to 2.5 mm2

(18 to 14 AWG).

• The recorder conforms to Installation Category II

of IEC 61010.

• All connections to secondary circuits must have

basic insulation.

• After installation, there must be no access to live

parts, for example, terminals.

• Terminals for external circuits are for use only with

equipment with no accessible live parts.

• If the recorder is used in a manner not specified by

the Company, the protection provided by the

equipment may be impaired.

• All equipment connected to the recorder's

terminals must comply with local safety standards

(IEC 60950, EN601010-1).

IMPORTANT (NOTE)

• Always route signal leads and power cables

separately, preferably in earthed (grounded) metal

conduit.

• Use screened cable for signal inputs and relay

connections.

• Replacement of the internal battery (type Varta

CR2025 3V lithium cell) must be carried out by an

approved technician only.
