WARNING: Wiring must conform to National Electric Code (NEC)
safety standards, as well as locally applicable codes. Failure to do
so could result in personal injury or loss of life.
See the product rating curve for wire gauge selection, ambient tem-
perature and current restrictions.
∫
WARNING: Only authorized and qualified personnel should install
and service the E-SAFE II Hybrid Power Switch. Failure to comply
with these recommendations may result in damage to equipment
and property and injury to personnel.

WARNING: Do not use an ungrounded wye- or delta-wired heater
configuration at 400 or 480V
Å
(ac).
Failure to follow all specifications and wiring instructions may result
in property damage, personal injury and/or loss of life.
ç
CAUTION: Provide proper enclosure ventilation to maintain an oper-
ating environment less than 70°C (158°F) maximum ambient rating.
Failure to do so could cause damage to equipment and property.
Torque Guidelines:
Properly torque line and load terminals to 2.25 nm (20
in-lbs).
These ratings apply to 3-phase units with cycle times of 30 sec-
onds or more. Consult the factory for 1- and 2-phase unit ratings.
U.L. Conditions of Acceptability
Applications must be tested as described below for spe-
cific wire insulation or specific wire gauge sizes. Tests
shall be performed in the end application under worst-
case operating conditions.
Test Procedure
A. Monitor the temperature of terminals, using
thermocouples between the ring terminal and
connectors L1, L2 or L3. The temperature must
not exceed 95
°
C.
B. Monitor the temperatures of wire insulation,
using a thermocouple located 3 inches from the
connector. The temperature must not exceed the
insulation rating of the wire.

WARNING: Thermocouples attached to terminals will be at load
voltage potential, measurements need to be taken with isolated
equipment or isolate the sensor from the terminal with suitable
insulation.
