VT170 & 190ESC 6 150-113Chapter 2: InstallationInstallation RequirementsMounting hardware supplied for easy installation. When determining the location for mounting, keep inmind the weight of the unit, available power connections, and access to peripheral equipment necessaryfor system operation. If installing a system outdoors, be certain to read the recommendations for outdoorinstallation provided elsewhere in this manual.ESCs require 4 Amps maximum at 120VAC, and 2 Amps maximum at 230VAC. Note that the unit is auto-sensing between 120VAC and 240 VAC. We recommend using 14-16 AWG wire and a 10-15A2-pole breaker in providing input power to terminal block.Systems must be securely mounted to a structure that will hold a weight equal to four times the unitweight (TS 500 = 66 lbs). The enclosure must have complete vertical and lateral support. It isrecommended that metal framing channels and fittings (such as Unistrut™ or Superstrut™) be used.Caution! Systems must be installed in a location capable of supporting four timesthe unit weight (see above). Failure to choose a suitable structure could cause theunit to become a hazard to personnel and equipment.To maintain the shock and vibration resistant features of the systems, pay close attention to the assemblysequence of the mounting hardware shown in Figure 2.Figure 2Vibration Isolator Mount BushingsRack or Cabinet MountIf a unit will be mounted in a rack or cabinet, the following requirements must be observed:1) Verify that there is sufficient airflow for safe operation within the rack or cabinet. Confirm that theinstallation will not exceed the maximum ambient temperature of 122°F (50°C) when combined withother installed equipment.
