Specifications

3.1.11.7 Heat Sink Access Panel
An optional heat sink access panel is available to facilitate
cleaning of the heat sink. Debris buildup is typical in
environments prone to airborne contaminants, such as the
textile industry.
3.1.11.8 Mains Disconnect
The disconnect option is available in both varieties of
option cabinets. The position of the disconnect changes
based on the size of the options cabinet and whether
other options are present. Table 3.10 provides more detail
about which disconnects are used.

NOTICE
In applications requiring UL listing, when the frequency
converter is supplied with a contactor, the customer
must provide external fusing to maintain the UL rating
of the frequency converter and a short circuit current
rating of 100,000 A. See 5.2.9 Fuses 5.2.10 Fuse Specifi-
cations for fuse recommendations.

3.1.12 F-frame Panel Options
Space Heaters and Thermostat
There are space heaters mounted on the cabinet interior of
F-frame frequency converters. These heaters are controlled
by an automatic thermostat and help control humidity
inside the enclosure. The thermostat default settings turn
on the heaters at 10 °C (50 °F) and turn them off at 15.6
°C (60 °F).
Cabinet Light with Power Outlet
A light mounted on the cabinet interior of F-frame
frequency converters increases visibility during servicing
and maintenance. The housing includes a power outlet for
temporarily powering tools or other devices, available in 2
voltages:
•
230 V, 50 Hz, 2.5 A, CE/ENEC
•
120 V, 60 Hz, 5 A, UL/cUL
Transformer Tap Set-up
If the cabinet light & outlet and/or the space heaters &
thermostat are installed, transformer T1 requires its taps to
be set to the proper input voltage. A 380-480/500 V drive
will initially be set to the 525 V tap and a 525-690 V drive
will be set to the 690 V tap to ensure no over-voltage of
secondary equipment occurs if the tap is not changed
before applying power. See Table 3.13 to set the proper
tap at terminal T1 located in the rectifier cabinet.
