Class I, Zone 1, Group IIC/IIB or
Class I, Div. 2, Groups A, B, C, D
Hazardous (Classified) Locations
Notes:
1.) Suitable separation must be maintained between Non I.S.
wiring of the relay circuits and I.S. wiring of the I/O modules
and the I.S. bus of the IS1 system.
2.) Do not disconnect Non I.S. field wiring to X1 or DOM Relay
base (9490/11-3.) from the BusRail unless area is known to
be non-hazardous.
3.) In hazardous locations classified Class I, Zone 1, Non I.S.
field wiring to the Ex e terminals X1 must meet the Class I,
Zone 1 wiring requirements of Canadian Electrical Code,
Part 1.
4.) At type 9477/12-06-12 relay circuit are grouped to two
groups, each using a common source. Additional protection
may be required to guarantee IP30 protection if a group is
only partly wired.
The Digital Output Relay Type 9477/12-0.-12 is an explosion protected
electrical apparatus for installation in a Class I, Zone 1, Group IIC/IIB or
Class I, Div. 2, Groups A, B, C, D hazardous location in accordance with
the Canadian Electrical Code, Part I that uses relay contacts to control up
to eight Non-I.S. circuits.
The internal system circuits are safely galvanically isolated from all output
circuits up to a peak voltage of 375 V.
Type 9477/12-08-12
Relay circuits may not exceed the following nominal values:
U

60 V AC
30 V DC
I

The output circuits are safely galvanically isolated from earth and from
each other up to an operating voltage of 60 V.
