ELECTRICAL INSTALL ATION
Permanently Connected Equipment:
Disconnecting devices shall be included in the system
installation. The disconnects shall be within close prox-
imity of the equipment, accessible to operators, and
marked appropriately as the disconnect for the associated
circuit. Assure the disconnect ratings are appropriately
sized for the circuit protected (See Specifications).
Circuit Separation:
Two cable entry locations are provided to aid in maintain-
ing separation of “hazardous live” (typically mains volt-
ages such as 115VAC and 230VAC) and limited circuits
(typically control voltages less than 30Vrms or 42.4VDC
such as the data communication signals). However, since
the
Wireless
EZ
Communication Interface's single wiring
compartment can not absolutely protect against physical
contact between multiple circuits, it is required that all
wiring used must have an insulation rating of 300v mini-
mum, and a temperature rating of 176˚F (80˚C) minimum.
Protective Earthing:
Each
Wireless
EZ
Communication Interface is provided
with a "protective conductor terminal" which shall be ter-
minated to the local earth ground potential. This terminal
shall be used to eliminate shock hazard in the unlikely
event of internal insulation breakdown. Select wire size
that can carry in excess of the sum of all circuit's maxi-
mum amperage.
EMI Optimizing:
(See Figure 5)
Ferrite beads are provided for installation in the wiring to
minimize affects of EMI. Wrap the large ferrite bead with
the incoming power wires (including protective earth con-
ductor) two to four full turns through the bead’s core.
Wrap small ferrite bead with incoming data wires(RS-485)
two to four full turns through the bead’s core. Position
each bead immediately inside the cable entrance of the
enclosure.
Power Input:
1) 85 to 265VAC Source:
(See Figure 6) Verify the
intended voltage supply is compatible with the voltage
configuration indicated on the electronics and the
external nameplate. Standard mains supply voltage
(85VAC to 265VAC as ordered) can be connected to
the unit's H/L1 and N/L2 terminals.
