Electrical connections

WARNING – Bodily injury
– 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 must be marked clearly as the
disconnection device for the recorder. A fuse must
be fitted in accordance with Fig. 10.
– 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 mm
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.
USA and Canada only
– The supplied cable glands are provided for the
connection of signal input and ethernet
communication wiring only.
– The supplied cable glands and use of cable/flexible
cord for connection of the mains power source to
the mains input and relay contact output terminals is
not permitted in the USA or Canada.
– For connection to mains input and relay contact
2
(18 to
outputs), use only suitably rated field wiring
insulated copper conductors rated min. 300 V, 14
AWG, 90C. Route wires through suitably rated
flexible conduits and fittings.
