Safety Information

Classification

The RM Series Backreflection Meter consists of an exposed metal chassis that is connected directly to earth via a power cord and, therefore, is classified as a Class 1 instrument.

Disconnecting from Line Power

Some of the circuits are powered whenever the unit is connected to the AC power source (line power). To ensure that the unit is not connected to the line power, disconnect the power cord from either the power inlet on the unit’s rear panel or from the AC line-power source (receptacle). The power cord must always be accessible from one of these points. If the unit is installed in a cabinet, the operator must be able to disconnect the unit from the line power by the system’s line-power switch.

Line Power Requirements

The RM meter operates from any single-phase AC power source that supplies between 100 and 240 V at a frequency range of 50 to 60 Hz. The maximum power consumption of the RM meter is 25 VA. The unit can also be operated using its internal 6V DC rechargeable battery.

Fuse Type

The fuse type used by the unit is (5 x 20) mm, 1 A/250 V (fast).
