Installation. Insert the mounting frame surface into the panel from its front surface. Note: The panel which is installed onto the flush type mounting frame f the timer cannot be inserted. (However, the installation der is not specified when the flush type mounting frame (type S) is used.) 2. After installing the panel, insert the timer to be used from the back of the panel. PMH TIMER OPTIONS When an applicable timer comes in contact with the collar of the mounting frame, stop the timer by pressing the upper and lower hooks in the direction indicated by arrow. Use rear terminal socket (AT784) 8P cap (AD8-RC) f the connection wiring. 3. Hang the hooks on the timer base to secure the timer to the flush type mounting frame.

Timers PRECAUTIONS IN USING PMH TIMERS PRECAUTIONS IN USING PMH TIMERS Precautions during usage In der to maintain the characteristics of PHM timer, do not remove the case. Please use within an ambient temperature range of to +5 C +4 to 22 F and in humidity no greater than 85% RH. Prevent using PMH timer in such places where flammable crosive gas is generated, a lot of dust exists considerable shock and vibration occur. Since the main body cover is made of polycarbonate resin, prevent contact with ganic solvents such as methyl alcohol, benzene and thinner, string alkali materials such as ammonia and caustic soda. Do not make direct solder connections to the round pins. Carefully verify the terminal numbers when wiring the terminal socket and cap. When rotating the knob, note that there are stoppers located just past the side and the full scale side. Therefe, do not use unreasonable fce. Please use with a time setting that is no than the minimum time limit. The minimum time limit is indicated on the dial by the mark. The contacts will not operate if the needle is adjusted to the position when the power is off. Phase synchronization f AC load switching When timer output contact will be synchronized to the AC power phase, the electrical life may be compromised and locking (contact reset failure) may occur due to contact welding contact transference. Therefe, please conduct tests using actual equipment. All Rights Reserved COPYRIGHT Panasonic Electric Wks Co., Ltd.
