If a CVT or UPS is to be used on the input to
the Control Panel, use a CVT with a Volt-Amp (VA)
output rating equal to or greater than the output
voltage multiplied by the control panel fuse rating
(see specification section). Also make sure that the
device input ratings correspond with the voltage
and frequency of the source supplied by the FUSED
DISCONNECT. The device output should be rated for
240 VAC maximum.
Before applying power to the control panel, verify
that it is set to match the source voltage. There may
sometimes be a voltage selection switch (usually
located on the DC power supplies) to select between
120 VAC and 240 VAC or different indicator bulbs
may be required.
INPUT POWER
Input supply voltage connections should be made from
a
FUSED DISCONNECT
that is located in an accessible
area near the Control Enclosure.
Electrical conduit is recommended for the input power wiring.
Use 3 cond. 14 ga. wire for incoming AC power supply.
If using SO type portable cord, a strain relief rated for
the diameter of cord being used is required for protection
against cord abrasion and damage.
The protective ground conductor must
be terminated directly to the protective
conductor ground terminal located inside
the Control Enclosure which is marked
with symbol -
If there are large AC line voltage fluctuations or voltage
transients such as those typically produced by heavy electric
machinery or welding equipment, then a constant voltage
transformer (CVT) or an uninterruptedly power supply (UPS)
should be used between the FUSED DISCONNECT and
the Control Panel.
