ENVIRONMENTAL
CONSIDERATIONS

This Isolation Transformer has environmental require­ments similar to other medical devices. It has been
designed for indoor use only, in areas where it will not be
exposed to excessive dust or moisture. Make certain that
there is adequate air flow around the unit. Do not place
objects on top of or near the unit which could obstruct the
air vents. For installation, please refer to the MICRO HD
CAMERA DZ-VCA1SE Instruction Book.

SIZING INFORMATION AND
INSTALLATION PROCEDURE

The name plate on the rear panel lists the Isolation
Transformer voltage and current ratings. Observe that the
input current rating is not exceeded when connecting
equipment. Ask that installation be performed by a JVC
authorized dealer.

OPERATING INSTRUCTIONS

SPECIFICATIONS

Turn all load equipment ON.
Turn the Isolation Transformer circuit breaker ON.

Observe that the front-panel green LED is illuminated.
Observe that the red LED (marked ) is not illuminated
(place the Isolation Transformer on a non-grounded
surface such as a carpet, wooden table, or magazine for
this test).

CAUTION:

If the red LED is continuously flashing, the wall receptacle
(powering the Isolation Transformer) is not connected to
the system safety ground. Immediately contact an electri­cian to correct the wiring discrepancy.

IMPORTANT NOTE:

The red LED is not intended to test general wiring integ­rity. Hot-neutral reversal, neutral-ground reversal, and/or
other wiring errors will not illuminate the red LED.

Once the Isolation Transformer has been properly in­stalled per the installation instructions, the Isolation
Transformer and load equipment can be turned ON/OFF
via the Isolation Transformer circuit breaker (and if not
externally circuit breaker equipped, via the panel circuit
breaker).

Symbols indicated on this equipment have the follow­ing meanings.
