PC 270 POWER CONVERTER INSTALLATION
PC 270 INSTALLATION AND GRO UNDING
Locate the PC 270 in an area that will allow proper access to the interior of the enclosure. Turn the knobs to open
the door for internal access. A standard lock may be used on the knobs for additional security.
Use the following guidelines for mounting the power converter:
Ensure that adequate space exists around the equipment for access during installation, maintenance, and
servicing.
Preplan the mounting location of the PC 270 before installation
Use the provided adjustable mounting bracket and hardware to mount the PC 270
Ground the PC 270 using a 2 AWG insulated wire to the tower. Route all ground conductors down and
away from the energized equipment and ensure there are no bends less than an 8 inch bend radius.
POWER CONVERTER (PC 270) WIRING
On the PC 270, input power is connected to terminal block TB1.
Mounted on TB1 is a Metal Oxide Varistor (VR1) which reduces line
surges and transients. Input power circuit breakers are also mounted
on TB1. Disconnect power from the FTC 270 before servicing circuit
breakers or MOV.
Flag Indicator on the 2-pole circuit breakers is clearly marked with
green OFF and red ON.
The power converters have an operational voltage range of 100-277
VAC, 50/60 Hz with no modification necessary to the input power
module.
The provided RS-485 communication cable will terminate on the
right side of TB1. Ensure you match the color-coding appropriately
to avoid communication issues and improper system operation.
