Warnings
Warning
: DO NOT connect the power supply module to external power before installing it onto the DIN
Rail. Failure to observe this warning could result in an electrical shock or death.
Warning
: Do not work on the PCVT-48VDC-53VDC, connect, or disconnect cables during a storm with lightning.
Failure to observe this warning could result in an electrical shock or death.
Warning
: Disconnect Device – Since the products are evaluated as Permanently Connected Equipment,
disconnect devices shall be provided in accordance with sub clause 1.7.2.2. A readily accessible disconnect device
shall be incorporated outside the equipment. These devices can be isolating switch, circuit breaker, or equivalent as

Restricted Access Note
WARNING
Disconnect power before installing and wiring the PCVT-48VDC-53VDC for power.
Failure to observe this warning could result in an electrical shock.
Wiring
considerations
The following wiring considerations are recommended:
Use separate paths to route wiring for power and device data cables. If power wiring
and device data cables must cross, make sure that the wires are perpendicular at
the intersection points.
DO NOT run signal or communications wiring and power wiring in the same conduit.
To avoid interference, wires with different signal characteristics should be routed
separately.
Keep input and output wires separated.
Label the wiring to all devices in the system for clarity.
Grounding
CAUTION
Connect the PCVT-48VDC-53VDC to a well-grounded surface. Failure to observe
this caution could result in electromagnetic interference (EMI) problems.
The PCVT-48VDC-53VDC can eliminate the effects of noise due to EMI via proper
grounding. Always run the ground connection from the ground screw to the grounded
surface before connecting power.
