5. INSTALLATION GUIDE
• Cut a square hole on the panel. The recommended hole size is 91 x 91 mm.
• Insert the meter through the pre-cut hole.
• Slide the retainer clips along any two guide slots located at the four corners of the meter
until the meter is tightly secured on the panel.
• The retainer clips can be removed by lifting the tab lightly at the handle end and pulling
it backward.

PRECAUTIONS
• Disconnect ALL power sources to the meter before performing installation, inspection
and maintenance.
• Please note that incorrect installation may impair the operation or even damage the me-
ter. There is no user serviceable part in the meter. Tampering with it may damage the

1. GENERAL DESCRIPTION
• DM36, DM36V and DM36A are multi-function, integrated digital meters with a large, clear
LED display, complete with selection buttons.
• Measurements include voltage, current, active power, power factor & frequency.
• The meters are con
fi
gurable for both single-phase and three-phase applications.
• Both DM36 and DM36V are self-powered and no auxiliary power is required.
• Using these meters, applications using multiple conventional analogue meters, indica-
tors and selector switches may be simpli
fi
ed to just a single meter.
