3 Installation
The equipment enclosure is rated at IP10 in accordance with IEC539. It is
designed for installation within a protective enclosure which prevents
unauthorised access except for trained service personnel, and prevents
contamination with conductive dust and condensation.
The voltages present in the FXM5 controller are capable of inflicting a severe
electric shock and may be lethal. The Stop function of the Drive does not remove
dangerous voltages from the FXM5 controller or the driven machine. AC supplies
to theFXM5 controller must be disconnected using an approved isolation device
before any cover is removed or service work is performed.
Electric shock risk
If the FXM5 controller has been energized, the supply must be isolated for at least
five minutes. This allows the internal capacitors to discharge fully before work
may continue.
Ground connections
The ground connections should be inspected and tested at appropriate and
regular intervals.
3.1 Hazardous areas
Approval and certification for hazardous areas should be obtained for the complete
installation of the motor, Drive and FXM5 controller.
3.2 Environment
In accordance with the IP10 rating of the FXM5, the FXM5 must be located in an
environment that is free from dust, corrosive vapors, gases and all liquids, including
condensation of atmospheric moisture (i.e. pollution degree 2 as required by UL840 and
IEC664-1).
If condensation is likely to occur when the FXM5 is not in use, install an anti-
condensation heater. This heater must be switched off when the FXM5 is in use;
automatic switching is recommended.
Install the FXM5 vertically for best flow of cooling air. When the FXM5 is installed in an
enclosure, install the FXM5 as low as possible (without contravening EMC
requirements).
Observe the requirements for ambient temperature if the FXM5 is to be mounted directly
above any heat generating equipment (such as a Drive).
3.3 Mounting instructions
Refer to section 3.8 EMC recommendations on page 9. Install the FXM5 controller on a
vertical surface (enclosure back-plate) with the heatsink fins vertical. Use the fixing
holes in the mounting brackets.
Allow at least 100mm (3.937in) clearance above and below the FXM5 controller to allow
free air-flow through the heatsink. Allow at least 3mm (0.118in) clearance each side of
the FXM5 controller.
