•
Barriers and power supply should be CSA certified. The specifications must not exceed the maximum values as shown in the diagram above. Installation should be in accordance with Canadian Electrical Code, Part I or CEC, Part I.
Maximum safe area voltage should not exceed 250 V
RMS
.
For
Class I,
Div.
2,
Group
ABCD
the
CSA
certified
barrier
is
not
required,
and
the
Sensor
input
circuit
(terminals
11
through
17)
is
non-
incendive
having
the
parameters
:
Maximum output voltage V
oc
=
14.4
V.
Maximum output current I
sc
=
88
mA.
Maximum allowed external capacitance C
a
= 3,5
F.
Maximum allowed external inductance L
a
= 10
mH.
•
The Hand Held Communicator must be of a CSA certified intrinsically safe type in case it is used on the intrinsically safe circuit in the hazardous area, or of a CSA certified non-incendive type in case it is used on the non-incendive circuit in the hazardous area.
