ZR-10
STANDBY POWER CONNECTIONS
The ZR-10 is suitable for temporary, standby, or emer-
gency power using the engine manufacturer
’ s recom-
mended maintenance schedule.
The ZR-10 can be permanently installed as a standby
power unit for 230V-3 wire, single phase 35 ampere
service.
(Connections must be made by a licensed electri-
cian who can determine how the 115/230V power
can be adapted to the particular installation and
comply with all applicable electrical codes.)
The following information can be used as a guide
by the electrician for most applications (refer also
to the connection diagram shown in Figure 1.)
• Install a double pole, double throw switch between
the power company meter and the premises discon-
nect.
• Switch rating must be the same or greater than the
customer ’ s premises disconnect and service over-
current protection.
• Take necessary steps to assure load is limited to
the capacity of the ZR-10 by installing a 35 amp
230V double pole circuit breaker. Maximum rated
load for the 230V auxiliary is 35 amperes. Loading
above 35 amperes will reduce output voltage below
the allowable-10% of rated voltage which may dam-
age appliances or other motor-driven equipment.
• Install a 50 amp 115/230V plug (NEMA type 14-
50)to the Double Pole Circuit Breaker using No. 8, 4
conductor cable of the desired length. (The50 amp
115/230V plug is available in the optional plug kit.)
• Plug this cable into the 50 amp 115/230V receptacle
on the ZR-10 case front.
WARNING
AUXILLIARY POWER WHILE WELDING
It must be noted that the above auxiliary power ratings
are with no welding load. Simultaneous welding and
power loads are permitted by following Table III. The
permissible currents shown assume that current is
being drawn from either the 115V or 230V supply (not
both at the same time). Also, the
“ Output Control ” is
set at “ 10 ” for maximum auxiliary power.
