Notes related to
CSA certification
for this module.
Note 1. Entity parameters per
channel: V
oc
= 27.9 V
I
sc
= 119 mA
C
a
= 84 nf
L
a
= 1.0 mH
Note 2. Maximum non-
hazardous area voltage must
not exceed 250 V.
Note 3. Install in accordance
with Canadian Electrical Code,
Part I, for installation in Canada.
Note 4. Install in accordance
with the NEC (ANSI/NFPA 70)
and ANSI/ISA RP 12.6 for
installation in the United States.
Note 5. To maintain intrinsic
safety, shield for each cable
must be grounded and must
extend as close to the terminals
as possible.
Note 6. Intrinsically safe (I.S.)
cables of one module must be
routed separately from I.S.
cables of another module.
Note 7. I.S. devices when
connected to I.S. terminals must
satisfy the following conditions:
V
oc
< Vmax
I
sc
< Imax

Note 8. This module is certified
as a component for mounting in
a suitable enclosure where the
suitability of the final
combination is subject to
acceptance by CSA or an
inspection authority having the
jurisdiction.
