Confirm that the voltage(s) and service configuration shown on the OVRHSP(SR) series product label are consistent
with the voltage and service configuration of the facility. A model number is on the right side of the OVRHSP(SR)
series unit. Each model number corresponds to the configurations printed in Table 1:
Pre-installation checklist
Confirm that the environmental conditions are consistent with the following ranges:
– Ambient temperatures: Between -40º to 70ºC (-40° to +158°F).
– Relative humidity: Between 5% and 95% non-condensing.
– Altitude: Less than 4000 m (13,000 feet).
