Rack Mounting the Power Meter
Rack Mounting Information
Disconnect Device Requirements
In rack mounting operation a disconnect device, for example, an IEC320
appliance coupler, must be used. Consideration must be given to the fol-
lowing when installing the power meter in a rack:
• An adequately rated switch (250V, 10A) or circuit breaker (250V, 5A)
shall be included in the rack.
• It should in close proximity to the power meter and within easy reach
of the operator.
• It shall be marked as a disconnect device.
Ventilation Requirements
When installing the power meter in a cabinet, the convection into and out
of the power meter must not be restricted. If the total power dissipated in
the cabinet is greater than 800 Watts, then forced convection must be
used.
