Location Planning

Consider the following when you decide where to install your
PowerFlex®
 product.
  • Environment - temperature, humidity, and vibration or shock
  • Ventilation and air conditioning
  • Input power cable entry points
  • Motor cable exit points
  • Product dimensions
  • Overall height of installation area
  • Alignment with other equipment
  • Future needs

Mounting Surface—Wall-mount Products

Install wall mounted products on a flat vertical surface.
  • Install the product in a vertical orientation.
  • Verify that the product makes full contact with the mounting surface.
  • Do not use standoffs or spacers.

Mounting Surface—Floor-mount Products

Install floor mounted products on a flat and level surface such that all enclosures in the line-up are within ±0.25 mm (0.010 in.) vertical orientation. If necessary, use metal shims to level the enclosures before joining them.
  • Install product enclosures in an upright orientation.
  • Verify that the product enclosures are square, vertical, and stable.
  • Verify that filters and debris screens are installed.
Various mounting options are acceptable.
  • Corner base/plinth system
  • Structural steel system
  • Anchor bolt system
  • Concrete screw system

Environment

The installation site must be compatible with the level of protection that is provided by the enclosure.
  • PowerFlex®
     755T products are only intended for indoor use.
  • Protect the equipment from moisture and direct sunlight.
  • Protect fans and electronics by avoiding dust or metallic particles.

Atmospheric protection
A harsh environment is defined as a copper or silver reactivity level greater than 1000 angstroms per 30 days exposure.
No condensation is allowed.
See ISA-71.04-2013 for details on how to measure reactivity levels on copper and silver test coupons.

Corrosive Environment Installations

The following requirements must be met for
PowerFlex®
 755T product installations in environments where corrosive gases are prevalent.
  • The
    PowerFlex®
     755T product must be manufactured with corrosive gas protection (XT) features that provide protection against contamination and corrosion.
  • All fiber-optic transceivers and printed circuit board edge connectors are coated with dielectric grease.
  • Apply dielectric grease to option card edge connectors before installation in the control pod. See the hardware service manual for your product for instructions on to apply dielectric grease and maintaining dielectric grease connections.
