➤ Check to ensure that a proper Xo bond is installed between the
neutral and ground terminals at the transformer upstream from
all 3ø WYE, 3ø high-leg DELTA, or 1ø SPLIT-PHASE TransEnd
devices (see NEC article 250.) Lack of a proper bond will dam-
age the TransEnd and void the warranty.
➤ Confirm that the environmental conditions are consistent
with these ranges:
Ambient Temperature: The TransEnd must be installed in
an area with a temperature between -40° and +140° F
(-40°and +60° C.)
Humidity: The TransEnd must be installed in an area with
relative humidity between 5% and 95%, noncondensing.
WARNING! Discontinue installation if (1) your conditions are
inconsistent with the guidelines above or (2) your conditions
cannot be verified. Call Joslyn Technical Support at 800.238.5000,
if you have any questions.
TransEnd is to be connected in parallel with the electrical
system and must be fed by an overcurrent protection device
(20A circuit breaker or fuse) in a power distribution panel.
Figures 1-4 show the relationship between the TransEnd
device and these four basic service configurations: WYE,
DELTA, High-Leg DELTA and SPLIT-PHASE.
