C.4 Outlet Louvres
1. A louvered grill on the heater outlet end is supplied as
standard. The louver assembly may be positioned either
horizontally or vertically for maximum flexibility.
2. Standard heaters are shipped with the louvers in the
horizontal position. To change the orientation of the
louvers to vertical, remove the three mounting screws
securing the louver assembly to the cabinet and rotate
the louver 90º to the desired direction.
C.5 Wiring
CAUTION
CAUTION. Whenever hazardous material are present,
ensure that the terminal housing covers, plugs, etc.,
are secured (but not over-tightened) before powering
the heater.
All circuits must be in the open position before
removing juncation or terminal box covers.
1. The heater must be installed by qualified personnel in
strict compliance with the electrical code.
2. All heaters are factory pre-wired and ready for direct
connections to the power supply leads.
3. The heater must be individually fused, preferably with
Class J time-delay fuses for maximum safety. Unless
stated otherwise in your local code, fuse size shall be
125% of line current or next size larger. See Table 2 and
Table 3, page 8 for recommendations.
4. Use approved conduit and conduit seals are required by
the code for the hazardous location.
5. The Norseman™ explosion-proof unit heaters are
equipped with a factory installed conduit seal between
the control and supply housings. In Division 2, Zone 1 and
Zone 2 applications, a field installed conduit seal may not
be required.
6. Supply wiring connections are made by accessing the
over of the side mounted supply connection housing
(terminal box). Slide the control trolley out of the housing
just enough to access the terminal block (Figure 8,
page 8).
7. Connect the power leads to terminals marked L1 and L2
for single phase and L1, L2 and L3 for three phase heaters
making certain to leave some excess wire to ensure that
the leads may slide back into the housing with the trolley.
See Figure 9 and Figure 10, page 9 for control circuit
and Figure 11, page 9 for suggested wiring. Exercise
care to avoid damage to wires caused by threads on the
housing.
