Considerations
Environment The device is designed to operate in an ambient temperature range of
-4 °F to +149 °F (-20 °C to + 65 °C) with a relative humidity of 0 to 95% non-
condensing. The operating temperature of the LCD on the diagnostic display
panel is -10 °C to +60 °C (+14 °F to +140 °F). Refer to the product catalog for
further details on enclosures. All EMA devices operate normally without
reduction in performance when subjected to shock and vibrations described in
IEC 60721-3-3, Class 3M4.
Audible Noise The device background noise is negligible and does not restrict the location of
the installation.
Mounting The device is designed to be surface or flush mounted. Refer to the device
submittal drawings or the product catalog for typical mounting dimensions and
weight.
Service Clearance The service clearance should meet all applicable code requirements.
Equipment Performance To obtain the maximum system performance, locate the device as close to the
circuit being addressed as possible to minimize the interconnecting wiring
length. For every foot of wire length, approximately 160 volts
(6 kV / 3 kA, 8/20 microsecond) is added to the suppressed voltage. The
Voltage Protection Rating (VPR) is located on the device nameplate and is
measured 6 inches from the enclosure sidewall, according to UL
