INSTALLATION - ELECTRICAL CONNECTIONS
Refer to the ‘Specification’ sheet in this manual for
Electrical Ratings.
1. Connect remote panel wires to Low Voltage
Control wires if applicable. If a remote panel is
not used, connect the red and white remote
switch wires and insulate the black wire.
2. Connect conduit cable to user supplied
electrical box.
3. Install a dedicated 30 AMP (see electrical
schematic) circuit protection breaker.
NOTE: If fuse replacement is required, then a
250 mA/0.320 ohm rated resistance time-delayed,
200% overload rated fuse should be used. This fuse
can be purchased through Bussman (Cooper), part
number MDL-1/4-R or contact your distributor for
replacement parts.
WARNING: Line voltage must be within
the specified voltage range 208-253
VAC. The 30 AMP breaker must be de-
lay/slow blow type. The breaker must
have a trip time of greater than 2 sec-
onds @ 400% overload.
WARNING: Connect in accordance with
NEC Class 2 wiring methods and all
applicable local codes.
* It is typical for industrial-type installations
(secondary or primary y-type transformers) to have
single phase power supplied from two legs of a
three-phase power source. In these instances,
large voltage drops and/or low initial voltage is
quite common (208 VAC or less). If the initial line
voltage is close to 208 VAC, then it is highly likely
that the system’s running voltage
will fall below the minimum
requirements. JUN-AIR strongly
recommends the use of a Buck/
Boost transformer (EK587 - See
‘OPTIONS-ACCESSORIES’) to
maintain an adequate running
voltage for these types of
scenarios, especially when
installing a JVAC7 system.
