1.2 Mounting the Unit
The unit is designed for panel mounting. The user should not be able to access parts of the
unit other than the front panel.
Mount the unit on a flat, vertical surface. The unit fits into a standard panel meter opening of
151x111
millimeters. Before mounting, remove the
pass the unit through the mo
unting opening. The unit will be maintained in its position by the
brackets spring.
Engine body must be grounded for correct operation of
the unit, otherwise incorrect voltage and frequency
measurements may occur.
The output of the current transformers shall be 5 Amperes. The input current rating of the current
transformers may be selected as needed (between

Install the fuses as nearly as possible to the unit in a
place easily accessible
The fuse rating should be 6 Amps.

3)
The building mains supply MUST incorporate appropriate short
protection (e.g. a fuse or circuit breaker) of High Breaking Capacity (HBC, at
