FCM II Installation Guide: 20160419 - Part # 2307
1.4.2 OPERATING CONDITIONS:
Operating temperature (surrounding air temperature) -40°F to 140°F (-40°C to 60°C).
Environmental Ratings: None. FCM II modules are classified as open equipment must be placed in a
suitable Type 4 (or IP 65) or better enclosure.
For product outline and dimensions see Figure 6.1 and Figure 6.2.
1.5 ELECTROSTATIC DISCHARGE (ESD) PROTECTION:
The FCM II contains electronic components and assemblies subject to damage by ESD. The FCM II was
designed to protect against ESD while the unit is mounted on an electrical panel and in normal operation. Proper
handling procedures must be observed during the removal, installation, repair and other handling of FCM II
modules summarized below.
1) Service must be performed by authorized personnel only.
2) The person performing the service must be grounded by an ESD grounding strap and connected to
ground.
3) The plastic enclosures offer a degree of protection of the inner printed circuit board assemblies
against ESD. However, the heat venting slots and the wiring terminals blocks do allow a possible path
for ESD when not fastened to the electrical panel. Therefore, a servicing technician is advised to
touch unpainted metal of the electrical panel prior to installing or replacing FCM II modules.
4) FCM II modules must be placed in and transported in conductive bags or other conductive containers.
5) FCM II modules must not be removed from the conductive container until time of use.
6) All other “best” practices for protecting devices from ESD must be observed.
